The&nbsp;Company’s primary focus is to develop distributed&nbsp;power generators that can operate on various fuel&nbsp;sources to future-proof against an ever-changing&nbsp;energy economy.</div>&nbsp;
Job Purpose
The Engineer, Test &amp; Validation is responsible for converting engineering and customer objectives into measured and validated results on the KARNO development team. The role covers the full test cycle: defining the test, assembling and instrumenting the hardware, executing the run, reducing the data, and presenting conclusions in technical review. Work spans KARNO Power Modules and Cores, linear generator and motor dynamometers, and component and subsystem rigs, and the resulting data directly informs program decisions. Because KARNO departs from conventional reciprocating and turbine architectures, using flameless oxidation to drive sealed helium through a thermodynamic cycle with a single magnet-carrying piston per shaft on pressurized helium bearings generating native 800 VDC, no established test methodology exists for a machine of this type. This position therefore carries significant influence over the test methods, rigs, and acceptance criteria against which KARNO is validated.

<li>Fixture, Jig, and Tooling Design: Design assembly and inspection fixtures, jigs, and tooling from concept through qualification. Own datum and locating strategy, tolerance stack-up and GD&amp;T, error-proofing (poka-yoke) features, and fixture qualification including repeatability and gage R&amp;R studies. Review and approve fixture designs produced by other engineers.</li>
<li>Material Handling and Flow Optimization: Design material presentation and handling systems that put the right part at the point of use in the right orientation — kitting strategy, cart and rack design, sequencing, kanban and pull loops, and travel distance and motion reduction. Partner with Supply Chain and Production Control on line-side stocking, min/max levels, and WIP control.</li>
<li>Waste Reduction in Assembly Operations: Systematically identify and eliminate waste across assembly operations — motion, waiting, rework, overprocessing, transport, and excess inventory. Reduce labor content and cycle time per unit through standard work, work sequencing, changeover reduction, error-proofing, and station design. Quantify the value of each change before implementation and verify the result afterward.</li>
<li>Prototype Development and Production Scaling: Collaborate with design engineering to develop prototype build processes and transition them to efficient, repeatable production-scale operations, including cross-site process transfer between the Milford, OH and Cedar Park, TX facilities.</li>
<li>Process Development and Optimization: Design, develop, implement, and qualify manufacturing processes for engine, generator, electric machine, and precision electromechanical assembly operations, including processes involving high-voltage systems, sealed pressure systems, and additively manufactured components.</li>
<li>Process Documentation and Control: Author and maintain the process documentation set — PFMEAs, control plans, work instructions, travelers, and routings — and ensure the manufacturing BOM structure reflects how the product is actually built. Verify on the floor that the documented process is the process being followed.</li>
<li>Technical Leadership and Mentorship: Serve as the subject matter expert for assembly process and fixture design. Provide technical guidance to production teams, mentor and develop manufacturing engineers and technicians, lead design reviews, and represent Manufacturing Engineering in engineering design reviews with the standing to influence design for manufacturability and hold configuration stability.</li>
<li>Capital Equipment and Automation: Specify, justify, procure, install, and qualify capital equipment, semi-automated assembly aids, and material handling equipment. Build the business case, run the vendor selection, and own installation and process qualification through to validated production use.</li>
<li>Additive Manufacturing: Integrate additive manufacturing technologies into production processes where applicable, including design and process considerations specific to additively manufactured assemblies.</li>
<li>Problem-Solving and Root Cause Analysis: Lead root cause analysis and corrective action for assembly process and quality issues using 5-Why, 8D, DOE, and statistical methods. Drive corrective actions to verified closure rather than disposition.</li>
<li>Project Management: Manage cross-functional industrialization projects, ensuring timelines, budgets, and objectives are met, and escalating early with a recommendation attached.</li>
<li>Safety and Ergonomics: Design workstations, fixtures, and material handling that support safe work — reach, lift, posture, tool access, and energy control. Participate actively in hazard identification, near-miss reporting, and LOTO and electrical safety discipline.</li>
<li>Additional duties and responsibilities as assigned, needed, or required for the business.</li>

Engineers in this group work across machine behavior, process optimization, material performance, data analytics, and hardware development to ensure high-quality, repeatable production using metal laser powder-bed fusion systems.&nbsp;
If you’re the kind of engineer who enjoys digging into machine behavior, fine-tuning laser strategies, studying how materials evolve layer by layer, and pushing metal AM systems to run cleaner, faster, and more consistently, this team is built for you. The work is hands-on, data-driven, and central to scaling a first-of-its-kind distributed power technology.
In this role, you’ll move across the entire additive manufacturing ecosystem. You’ll investigate how machine settings influence melt pools, porosity, and microstructure, and you’ll design controlled experiments to refine parameters and boost repeatability. A big part of the job involves troubleshooting machine quirks, interpreting sensor data, and making sense of real-time process feedback. You’ll also be working closely with design, materials, and hardware teams to bring complex AM components from early prototypes into reliable production. Along the way, you’ll help build the systems, standards, and workflows that turn metal AM into a high-trust, high-reliability manufacturing process for power-generation hardware.
