Security Clearance

U.S. citizenship required. An active Secret security clearance is required on day 1.

Domestic travel approximately 15‑25% expected.

The Sr. Principal Systems Engineer will support Digital Radar test activities, including radar performance analysis and Flight Test mission support.

Key responsibilities include:

• Generate, run, and interpret modeling and simulation scenarios to predict radar performance, validate algorithm updates, and compare modeled results to Flight Test truth data.
• Support real‑time and near‑real‑time field analysis during test events, providing reach‑back to development teams, interpreting data products onsite, validating sensor behavior, and advising mission leadership on radar system status and performance.
• Collaborate with group leads, cross‑discipline engineers, program leadership, and government stakeholders to define analysis objectives, prioritize data sets, and communicate findings.
• Produce technically rigorous analysis reports, performance assessments, test‑event summaries, and presentation materials for internal reviews and external customer briefings.
• Contribute to technical reviews such as peer reviews, gate reviews, verification events, and test readiness reviews, ensuring analytical rigor and alignment with program objectives.
• Support engineering activities, including systems validation, algorithm performance assessment, data analysis methodology development, and test‑event reconstruction for complex digital radar systems.
• Actively participate in planning for Ground Test and Flight Test events by defining data‑collection requirements, identifying key performance measures, preparing analysis tools, and coordinating readiness with integration and test teams.
• Ensure that test and evaluation activities are conducted in accordance with established engineering processes, quality standards, and government test requirements.

• Minimum 10 years of relevant experience in systems engineering, radar waveforms, beamforming, or signal processing.
• Degree in a STEM field (Science, Technology, Engineering, or Mathematics).
• Proficiency with MATLAB, Python, or other programming languages.
• Experience with system integration, verification, validation, and testing.
• Experience with technical and/or functional leadership.

• Experience supporting Flight Test planning, execution, or post‑test data analysis.
• Demonstrated experience in test, integration, or verification and validation of Missile Defense System, Army, or Navy sensors.
• Experience working within multidisciplinary systems engineering teams.
• Experience interfacing with internal or external customers, providing technical solutions to user requirements, analyzing radar data, and generating technical documentation.
• Experience supporting development of verification/validation strategies for advanced radar capabilities and software builds, including building and executing simulated scenarios.

• Relocation assistance available.
• Medical, dental, vision, life insurance, short‑term and long‑term disability.
• 401(k) match, flexible spending accounts, and flexible work schedules.
• Employee assistance program, parental leave, paid time off, and holidays.
