IonQ is making quantum platforms more accessible and impactful than ever before. &nbsp;</div><h2>Role Overview</h2><h2>Role:</h2>We are looking for a customer obsessed, systems minded product leader to build the vision and specifications for the software and tooling that will deliver the best quantum fleet management in the world, for IonQ and for our customers. As a Senior Staff Product Manager within IonQ's Quantum Computing product family, you will join a cross functional team whose mission is to build and deliver the world's best quantum computers to solve the world's most complex problems.In this role, you will own Fleet Management and the platform that enables it as a product offering. That covers telemetry and observability, remote management, incident response and planned service, together with integration into the commercial operations, deployment and logistics information and tools that let IonQ grow from per system, per site operations to high leverage, coordinated management of every system we deploy, wherever it lives.Fleet management is both a product area and part of what we sell. Once a system is delivered, on a customer site or in our own cloud, our managed service keeps it running for the life of the contract. Today that work is done well by skilled people, but the tooling behind it was not built to scale. You will turn it into a first class offering, where uptime is treated as a design requirement and is achieved through great tools rather than heroics.This is a global remit. As our fleet grows across North America, Europe and Asia, you will help us move to a follow the sun model, supporting systems from a small number of operations centres rather than placing people at every site.<h2>Responsibilities:</h2>You will start by treating the people who run and support our systems as your customers: internal and customer fleet operations, reliability, commercial operations, service and support. You will spend real time alongside them to learn how they work today, where the toil, blind spots and heroics are, and what good would look like for each of them, and you will build a strong point of view on what it takes to run a resilient, highly available global fleet of quantum computers.You will immerse yourself in IonQ's system architecture, control and classical infrastructure, data pipelines, build and maintenance motions, and the current state of our tooling. Working closely with resilience, operations and engineering leads, you will understand what is possible, what is already in flight and where the constraints sit, and you will turn a diffuse set of pains and desires into a clear vision and roadmap.From there, you will lead cross functional efforts to simplify, streamline and ship. Where we build, you will partner with SRE and engineering to define requirements, sequence work and land it. Where we buy, you will drive selection and rollout. Where the gap is process or communication, you will work with the PMO and the teams involved to improve it, and you will establish clear interfaces between Compute Products and the operations and commercial teams who depend on this tooling.You will instrument what you ship, using feedback, support volume, incident and availability data and resolution metrics to understand whether the tools are working and where to go next. You will also help feed what we learn about operability and maintainability back into how we design and ship the next hardware generation, and begin extending the platform to customers as they take on more of their own system operation.<h2>Key responsibilities include:</h2><ul><li>Build a deep understanding of how internal and customer fleet operations, reliability, service and support teams run our systems today, and where they need better tools</li><li>Define and own the vision and roadmap for fleet management across telemetry and observability, operator and back office tools, SLA, SLO and availability tracking, sparing and maintenance planning</li><li>Establish north star metrics for fleet health and operational effectiveness, and make them visible across the company</li><li>Lead build and buy decisions with SRE, engineering and the PMO, and set clear interfaces between Compute Products and the teams who depend on this tooling</li><li>Use incident, availability and support data to iterate, feed operability lessons into future hardware generations and extend the platform to customers</li></ul><h2>Requirements:</h2>To be successful in this role, you will bring substantial experience in technical product management, ideally with direct ownership of internal platforms, operational tooling or infrastructure software. Most great product managers did something else first, and here we are especially interested in people whose earlier careers were in engineering, fleet or network operations, process engineering or systems engineering, so that they understand what operational data is for and how the day to day workflow really runs.You will be a high agency, high accountability product leader who brings your own energy to an ambiguous area and drives impact through persistence and adaptability. This is a product leadership role rather than an operations or programme management role: we want someone who thinks about fleet management as an offering and a book of work, not someone who carries out the hands on management themselves.You will have enough technical fluency to work directly with SREs and engineers on telemetry, process flows, data pipelines and API surfaces as first class products, and the empathy to sit shoulder to shoulder with the people who keep complex systems running. Experience of low volume, high complexity frontier technology, from R&amp;D through to first deployments, will serve you well here.Communication matters a great deal in this role. You will need excellent written and verbal communication, with a proven ability to explain complex topics clearly to technical and non technical audiences, from engineering teams to company leadership and customers. You do not need a background in quantum computing; we care more about how you think, how you learn and how you lead.<h2>You’d be a great fit with:</h2><ul><li>A degree in Computer Science, Engineering, Operations Research or a related technical field, or equivalent experience, with 12+ years in technical product management or equivalent roles</li><li>Product experience with private cloud deployments, scientific computing or high performance computing platforms, including their tools, users, business models and operational challenges</li><li>Experience building or scaling tooling for distributed, high value physical infrastructure, such as data centre or HPC operations platforms, DCIM or observability stacks, or remote field service for scientific instruments or connected hardware</li><li>Experience with AI tooling and workflows, both for rapid prototyping and for predictive, self healing or agentic product offerings</li><li>Experience taking internal tools through to customer facing products, familiarity with quantum computing or deep tech R&amp;D, or experience leading and mentoring other product managers</li></ul>The total compensation package includes base salary, bonus, equity, and a range of benefits available on our career site.<div class="content-conclusion">Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity.

IonQ is making quantum platforms more accessible and impactful than ever before. &nbsp;</div>Location:&nbsp;Oxford, UK Office commitment: Hybrid
The Role:
We are looking for a highly technical Staff Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building and operating the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock.
The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output.
Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit.
The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned.
You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them.
This is a hands-on engineering role: you would be writing this software alongside our other staff engineers, not directing others who write it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required.
&nbsp;
Responsibilities:
In this position, you will work across the services that make up the control plane, supporting the effective delivery of a system every machine in the fleet depends on.
You'll have the opportunity to remove whole classes of failure and raise the bar for the engineers around you, contributing directly to the success of the System Software function.
Key responsibilities include:
<ul>
<li>Take on the problems that span the whole control plane - the durability and recovery contracts the rest of the design rests on.</li>
<li>Make a machine's own assessment of its readiness something the rest of the control plane can rely on.Do the deep diagnosis of failures that only appear on a live system, under real load.</li>
<li>Remove whole classes of failure across the fleet, rather than instances of them.</li>
<li>Draw the boundaries between our services, settle them in writing, and move the code across them yourself.</li>
<li>Make the correctness of a design demonstrable rather than argued.</li>
<li>Build the tooling and test infrastructure that let the whole team move faster.</li>
<li>Evolve how our services are deployed and operated as the fleet grows.</li>
<li>Raise the bar of everyone around you through the code you write and the reviews you give.</li>
</ul>
&nbsp;
Requirements:
To be successful, you will need deep systems engineering experience, a track record of operating services where losing data is not an option, and the judgement to tell a problem worth solving structurally from one worth patching. We're looking for someone who wants to stay hands-on in the code at this level and can contribute effectively within a fast moving, highly technical team.
You'd be a great fit with:
<ul>
<li>Expert systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming.</li>
<li>Deep experience building and operating stateful networked services in production, exposed over gRPC or REST, with a real grasp of error handling, observability and failure modes.</li>
<li>A track record with data durability and correctness - persistence design, crash recovery, and migrations against live data you cannot afford to lose. We use PostgreSQL.</li>
<li>The instinct to reach for determinism when chasing a timing or interleaving bug, rather than for more logging.</li>
<li>Depth in the scheduling and workflow landscape - Temporal, Hatchet, Airflow, Slurm, Postgres-backed queues - and the judgement to borrow from it rather than reinvent.</li>
<li>A track record of pinning down failures that others could not.</li>
<li>A habit of settling design questions in writing, with the options compared as peers.</li>
<li>Excellent communication skills both within software and across disciplines.</li>
</ul>
Additional useful experience would include replacing a load-bearing system while it stays in service, containerised services in production, Kubernetes and declarative deployment, distributed tracing, formal specification or model checking, closed-loop systems that act on measured state, and scientific computing or research facilities.

Location:&nbsp;Oxford, UK Office commitment: Hybrid
The Role:
&nbsp;
We are looking for an enthusiastic Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock.
The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output.
Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit.
The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned.
You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them.
You will own features end to end, from the API through to the rollout onto real machines. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required.
&nbsp;
Responsibilities:
In this position, you will work on the services that schedule work onto our quantum computers and keep the record of it, supporting the effective delivery of a control plane the whole fleet depends on.
You'll have the opportunity to own real pieces of that system end to end, contributing directly to the success of the System Software function.
Key responsibilities include:
<ul>
<li>Build and extend the services that schedule work on our systems and keep the record of it.</li>
<li>Build the mechanisms that decide when a system needs re-tuning, and get those calibrations run.</li>
<li>Own what we persist: the data model, its migrations, and the code that reads and writes it.</li>
<li>Produce the tests and harnesses that let our code be exercised against real hardware and against simulators.</li>
<li>Work with the systems teams to roll releases out across the fleet and support them once they are running.</li>
<li>Improve the observability of the code you ship.</li>
<li>Take part in code review, and improve the APIs our internal users depend on</li>
</ul>
Requirements:
&nbsp;
To be successful, you will need solid programming skills, an interest in the systems that keep long-running machines working, and either experience of a systems programming language or the appetite to learn one. We're looking for someone who can work comfortably in a Linux environment, cares about what happens to data when a service crashes or a migration goes wrong, and can contribute effectively within a fast moving, highly technical team.
You'd be a great fit with:
<ul>
<li>Strong programming skills in one or more mainstream programming languages.</li>
<li>Experience with a systems programming language. Our System Orchestration layer is written in Rust, so either some Rust experience or the appetite to learn it.</li>
<li>Comfort with relational databases and SQL; we use PostgreSQL.</li>
<li>Some exposure to networked services and APIs, such as gRPC or REST.</li>
<li>Exposure to schedulers, job queues or workflow engines - Celery, Airflow, Temporal, Slurm or similar.</li>
<li>Comfort working on Linux, and debugging a service that is already running.</li>
<li>Good communication skills both within software and across disciplines.</li>
<li>A habit of producing appropriate tests and taking part in code review.</li>
</ul>
Additional useful experience would include async programming, containers and Kubernetes, closed-loop systems that act on measured state, and scientific computing or research facilities.

Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom.

IonQ is making quantum platforms more accessible and impactful than ever before. &nbsp;</div>Location:&nbsp;Oxford, UK Office commitment: Hybrid
The Role:
Quantum is now, and it's built here. Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world-leading trapped-ion technology, we're building the most powerful, accurate and reliable quantum systems to tackle problems that today's supercomputers cannot solve.
We're looking for an enthusiastic and highly technical Staff Software Engineer for our non-realtime controllers team who will thrive in our dynamic cross-disciplinary environment. You'd be working closely with our skilled software engineers, our systems teams who operate the physical quantum computers, and our world-leading quantum scientists to build and operate the software that controls the hardware surrounding our quantum computers. Previous exposure to quantum systems is not required.
You will take on our most demanding hardware integrations and the framework work that makes every other controller better. This is a hands-on engineering role: you would be the most experienced engineer writing controllers, not the one directing others to write them.
A working quantum computer is far more than the ion trap and its real-time control electronics. It depends on a fleet of supporting hardware, including cryogenic compressors, vacuum pumps, power supplies, lasers, temperature controllers, wavemeters and cameras, that has to be kept observable, controllable and reliable. The timing-critical operations such as gate waveforms and ion transport run on dedicated real-time FPGA systems, while this team owns everything that does not need hard timing guarantees. These services run on general-purpose Linux hardware and must be rock-solid, because a failed compressor or an un-noticed pressure drift takes a whole machine offline.
Responsibilities:
This is a hands-on engineering role. Your influence comes from the code you ship and review, and from the problems you take off everyone else's plate.
Key responsibilities include:
<ul>
<li>Take on our most demanding device integrations, and do the deep diagnosis of problems that only appear against real hardware in a live lab.</li>
<li>Remove whole classes of failure across the fleet, rather than instances of them.</li>
<li>Improve the shared framework yourself, and bring the existing controllers along with each change.</li>
<li>Build the tooling, simulators and test infrastructure that let the whole team move faster.</li>
<li>Evolve how our services are deployed and operated as the fleet grows, and make the fleet observable enough that problems are found early.</li>
<li>Raise the bar of everyone around you through the code you write and the reviews you give.</li>
</ul>
Requirements:
To be successful, you will need deep systems engineering experience, a track record of shipping and operating reliable services, and the judgement to tell a problem worth solving structurally from one worth patching. We're looking for someone who wants to stay hands-on in the code at this level rather than move away from it.
You’d be a great fit with:
<ul>
<li>Expert systems engineering skills. Our controllers are written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming.</li>
<li>Experience building and operating networked services in production such as gRPC or REST, with a real grasp of error handling, observability and failure modes.</li>
<li>Experience of hardware and instrument protocols and interfaces such as SCPI, Modbus, serial and Ethernet.</li>
<li>A reputation as the person people bring the undiagnosable bug to, and the ability to prioritise work with a clear understanding of critical versus urgent items.</li>
<li>Excellent communication skills both within software and across disciplines.</li>
</ul>
Benefits
Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing.
We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more.

The Role:&nbsp;
We are looking for a Systems Software Engineer to join our Runtime Software team at Oxford Ionics / IonQ. In this role, you will be responsible for working directly with the experimental scientists to implement the real-time control system behaviours and provide abstractions they require for their experiments, contributing to the team’s mission of enabling our science teams to experiment and improve the primitive operations which allow compute, and building towards fault tolerant computation.
You’ll play an important part in shaping the core, Rust, libraries and the execution environment which take our system from a collection of hardware to a quantum computer, and support our work in building the world’s most advanced quantum systems.
&nbsp;
Responsibilities:
In this position, you will work on developing abstractions over real-time control hardware, supporting the effective delivery of a control system capable of repeatedly and reproducibly driving our ions with nano-second level precision, with abstractions which are conducive to both fast iteration and system scaling.
You’ll have the opportunity to accelerate the science core to the development of our systems, and contribute to the core execution model of our quantum computers, contributing directly to the success of building utility-scale quantum computers.
Key responsibilities include:&nbsp;
<ul>
<li>Collaborating with scientists to understand their requirements.</li>
<li>Interfacing with system orchestration, non-realtime control and compiler teams to ensure our work integrates seamlessly with the wider software architecture.</li>
<li>Implementing drivers for various real-time devices.</li>
<li>Producing tooling to enable users of our code to iterate rapidly and fearlessly.</li>
<li>Developing the execution environment for the user programs which run on our systems.</li>
<li>Continually improving the APIs used by our internal users.</li>
</ul>
&nbsp;
Requirements:
To be successful, you will need expert programming skills in a systems programming language and a desire to produce high quality code appropriate to a real-time environment. We’re looking for someone who can quickly iterate on low-level code in a collaborative, cross-disciplinary, environment and contribute effectively within a fast moving, highly technical team.
You’d be a great fit if you:
<ul>
<li>Have strong programming skills in one or more mainstream programming languages</li>
<li>Have experience with a systems programming programming</li>
<li>Have an interest in or experience with Rust</li>
<li>Have developed excellent communication skills both within the context of software and across disciplines</li>
<li>Are comfortable working with rapidly evolving requirements</li>
<li>Are used to maintaining and producing high quality code reviews and appropriate testing</li>
<li>Have a desire to maximize impact through quick iteration and short cycles of learning and improvement</li>
<li>Are eager to learn and develop your skills</li>
