Senior GNC Engineer

Strativ Group is partnering with a fast-growing aerospace and defense company building mission-critical flight systems. This is a confidential search. The role You’ll make the math run in the box. You’ll take navigation filters, guidance laws and autopilot control laws from MATLAB/Simulink to real-time embedded flight code, and build the SIL and HIL infrastructure that proves it works, from algorithm to silicon. What you’ll do Implement the GPS/INS navigation filter, guidance and control laws in embedded C/C++ on the flight computer. Own the GNC flight software architecture: scheduling, sensor interfaces, the state machine and fault detection. Build the SIL environment against a 6-DOF model, and design the HIL test bench from scratch. Set coding standards (MISRA-C), run code reviews, and own GNC software verification and testing. Characterize real-time performance: CPU budget, worst-case execution time, jitter and latency. Act as GNC software technical lead through environmental, ground and range testing. What you’ll bring 8+ years of embedded flight software experience on flight-critical defense or aerospace systems. A B.S. or M.S. in Computer, Electrical or Aerospace Engineering. Expert C/C++ on RTOS and bare-metal systems. Production implementation of Kalman filters or flight control laws. MATLAB/Simulink with Embedded Coder auto-code generation. SIL and HIL test infrastructure experience. U.S. citizenship and eligibility to obtain and maintain a security clearance. An active Secret or Top Secret clearance. DO-178C experience. GPS receiver interfaces, including M-code or SAASM. High-g IMUs and avionics. MIL-STD-1553, RS-422 or ARINC 429. FPGA co-design. High ownership on real flight hardware. Series-A company scaling fast. #J-18808-Ljbffr Strativ Group
