Northrop Grumman Aeronautics Systems has an opening for a Principal Systems Engineer or a Sr. Principal Systems Engineer Electromagnetic Environment Effects (EEE) to join our team of qualified, diverse individuals within our Systems Engineering Team. This position is located on-site in two locations; Palmdale, CA. and Melbourne, FL.
Performs technical planning, system integration, verification and validation, cost and risk, and supportability and effectiveness analyses for total systems. Analyses are performed at all levels of total system product to include: concept, design, fabrication, test, installation, operation, maintenance and disposal. Ensures the logical and systematic conversion of customer or product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints. Performs functional analysis, timeline analysis, detail trade studies, requirements allocation and interface definition studies to translate customer requirements into hardware and software specifications.
Essential Functions:
- All programs have E3 requirements, so an E3 engineer must be capable of writing, interpreting, allocating, tailoring and flowing down E3 requirements to all design levels.
- E3 engineers interact across all phases of a program, so strong technical communication skills and a readiness to explain complex technical issues with brevity to an audience unfamiliar with the E3 topic are necessary.
- E3 engineers need to present at design reviews to internal and external customers regarding E3 issues.
- An E3 engineer must be capable of writing E3 design guidelines, developing models and performing analyses on components, subsystems and systems using EMI principles.
- E3 engineers are responsible for designing ground systems, chassis and harness shielding, EMI filters, and selecting and laying out interface circuitry for achieving EMC.
- E3 engineers are required to prepare and review E3 test procedures, E3 test reports, E3 technical analyses, E3 control plans, and participate in cross discipline design reviews for EMC.
- To verify E3 requirements, E3 engineers need to design E3 test procedures and participate in E3 testing in accordance with governmental and non-governmental standards, for example MIL-STD 461, MIL-STD 464, DO-160.
- Experienced E3 engineers at Northrop Grumman must help maintain and build on Aerospace System’s reputation for E3 expertise and quality by training and mentoring less experience E3 engineers.
- E3 engineers must contribute to the overall knowledge and expertise in E3 engineering capability by developing processes, procedures, documentation, and protocols for the practice of E3 engineering at Northrop Grumman.
Basic Qualifications:
- (Principal) Bachelor’s degree in a Science, Technology, Engineering, or Mathematics (STEM) discipline from an accredited university and 5 years of experience OR Master’s degree in a Science, Technology, Engineering, or Mathematics (STEM) discipline from an accredited university and 3 years of experience.
- (Sr. Principal) Bachelor’s degree in a Science, Technology, Engineering, or Mathematics (STEM) discipline from an accredited university and 8 years of experience OR Master’s degree in a Science, Technology, Engineering, or Mathematics (STEM) discipline from an accredited university and 6 years of experience.
- Active DOD Secret Security Clearance
- Ability to obtain and/or maintain special program access before start of employment.
- Experience with MIL-STD-464 or MIL-STD-461
- 1 year of experience in RF, Test or design engineering.
Preferred Qualifications:
- A Bachelor’s degree in Electrical Engineering, with a specialty in Electromagnetics, RF, or analog circuitry.
- Experience with defense and aerospace industry practices, and programmatic skills supporting BOE, RFP, ROM, CAM, WBS, Risk assessments for E3 compliance is a plus for candidates.
- Ideal candidates can show extensive design experience with EMI filters, circuit layout and analysis for E3, shielding, lightning protection, cable and harnessing design.
- Candidates with working knowledge and experience in modeling and simulation of E3 using commercially available software is a plus.
