Raytheon’s Surface Radars and Sensors (SR&S) Center, Huntsville AL Department, is seeking a Sr. Principal Systems Engineer to support Digital Radar test activities, including radar performance analysis and Flight Test pre and post mission activities. In this role, you will take on widespread engineering responsibilities such as planning and executing radar test events, conducting in-depth radar data analyses, and developing and implementing verification strategies for advanced radar capabilities and software builds across HWIL, SIL, and field environments. You will leverage radar-domain expertise to analyze system behavior, evaluate algorithm and software performance, and diagnose the root causes of anomalies. Your tasks will include creating test objectives, specifying data collection requirements, analyzing mission and sensor data to evaluate performance in detection, tracking, discrimination, and engagement, and sharing results with multidisciplinary engineering teams. You will collaborate with systems, software, and algorithm engineers while also working independently to support requirements validation, technical reviews, and readiness for Flight Test events. This position may require occasional travel to Raytheon and government sites to assist with integration efforts, test events, and technical discussions.

What You Will Do

• Generate, run, and interpret modeling and simulation scenarios to predict radar performance, validate algorithm updates, and compare modeled results to Flight Test truth data and measured radar outputs.
• Support real‑time and near‑real‑time field analysis during test events by 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 suitable for internal reviews as well as 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, including data capture, software/hardware configuration tracking, and validation procedures, are conducted in accordance with established engineering processes, quality standards, and government test requirements.
• Domestic travel is expected, approximately around 15-25%.

Qualifications You Must Have  

• Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 10 years of prior relevant experience.
• Experience with radar waveforms, beamforming, and/or signal processing.
• Experience with MATLAB, Python, and/or other programing languages.
• Experience with system integration, verification, validation and/or testing.
• Experience with technical and/or functional leadership.

Qualifications We Prefer

• 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, and/or Navy sensors.
• Experience working within multidisciplinary systems engineering teams.
• Experience interfacing with internal or external customers, including providing technical solutions to user requirements, analyzing radar data, and generating and maintaining technical documentation and work instructions.
• Experience supporting development of verification/validation strategies for advanced radar capabilities and software builds, including building and executing simulated scenarios to predict sensor performance.

What We Offer:

• Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value: Safety, Trust, Respect, Accountability, Collaboration, and Innovation.
