Senior GNC Engineer

Strativ Group; Irvine (CA); On-site; USD 140,000 - 210,000; Full time

Job summary

Strativ Group is partnering with a fast-growing aerospace and defense company building mission-critical flight systems in Irvine, CA. You’ll translate MATLAB/Simulink models into real-time embedded flight code and develop SIL/HIL infrastructure from algorithm to silicon.

You’ll own the GNC software architecture, implement GPS/INS filters in C/C++, and drive coding standards, verification, and testing for safe, high-performance flight software.

Qualifications

• 8+ years of embedded flight software experience on flight-critical defense or aerospace systems.
• 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.

Responsibilities

• 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.

Job description

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.
