Our organization within Northrop Grumman Mission Systems offers the opportunity to join a team to solve problems in the field and drive new solutions into next generation systems across a wide variety of platforms and environments. You will support the Systems Engineering Integration and Test (SEIT) team on multiple major development programs. This position is based out of Linthicum, MD and will be 100% on-site. What You'll get to Do: Develop radar system architectures for air‑to‑ground missions (e.g., SAR, ISAR, GMTI/T, Targeting, Weather, Surface Return, Sea Surface Search, Ship Track, etc.). Lead requirements analysis, allocation, and flow‑down to subsystems (RF front‑end, signal processing, interfaces). Own and maintain system/subsystem specifications and ICDs, ensuring traceability to mission and platform needs. Perform radar performance modeling (SNR, detection range, resolution, clutter, false alarm rates). Conduct trade studies on waveforms, antenna configurations, processing approaches, and platform constraints. Use modeling tools (MATLAB, Python, etc.) to evaluate design options and support technical decisions. Plan and execute lab, field, and flight tests to verify radar performance against requirements. Develop test procedures, define success criteria, and analyze test data to identify issues and drive corrective actions. Support problem‑solving across hardware, software, and signal processing teams. Serve as a key technical contributor within multi‑disciplinary teams. Prepare and present technical material for internal reviews and customer briefings. Support proposals and technical volumes, contributing to concepts, architectures, and estimates. This position is contingent upon the successful transfer of an active U.S Government Secret Clearance and the ability to obtain Special Program Access.
