Software Engineer, Avionics

About The Team

The Avionics Team owns the electronics on the vehicle: flight computer, compute boards, power conversion, sensor interfaces, wiring, and the embedded firmware that ties them together. The same engineers design the boards, write the firmware, and bring them up at the bench. No handoff layer between hardware and software. Avionics sits on the critical path for every flight test, so the team s velocity sets the program s pace.

We are seeking an exceptional avionics software engineer to develop embedded systems and flight-critical software architectures for advanced aerospace platforms. You will work across hardware, firmware, and real-time software systems while collaborating directly with electrical, controls, and mechanical engineers. You will own mission-critical avionics software that directly interfaces with flight hardware and operational systems, not isolated subsystems or legacy code. This role is ideal for engineers who want broad technical ownership, rapid iteration cycles, and the opportunity to build systems that move from concept to flight quickly.

• Develop embedded avionics software in C/C++ and Rust
• Design real-time software architectures for flight systems
• Interface directly with avionics hardware, sensors, and communication systems
• Develop software for power systems, telemetry, control systems, and onboard computing
• Write the embedded servo firmware for the fin actuators: current loop, position loop, commutation, command interface, and fault handling. Implement to the Control Actuation Engineer s control law spec; tune with them on the bench
• Support hardware bring-up, integration testing, and flight operations
• Build robust testing and simulation frameworks
• Participate in system-level architecture and safety reviews
• Optimize performance, reliability, and fault tolerance of embedded systems
• Collaborate closely with cross-functional engineering teams

• BS/MS in Computer Engineering, Electrical Engineering, Aerospace Engineering, Computer Science, or related field
• 5+ years of embedded software development experience
• Strong proficiency in C/C++
• Experience with real-time systems and embedded Linux or RTOS environments
• Experience debugging hardware/software interactions
• Familiarity with communication protocols such as CAN, SPI, I2C, UART, and Ethernet
• Strong systems-level thinking and troubleshooting ability
• Motor-control firmware experience: current and position loops, FOC or trapezoidal commutation, sensored or sensorless schemes, and real-time scheduling on a motor-control MCU
• Excellent communication and teamwork skills

• Experience with aerospace, automotive, robotics, or autonomous systems
• Rust experience
• Experience with DO-178 or safety-critical software processes
• FPGA or low-level hardware interface experience
• Experience with telemetry, flight controls, or navigation systems
• Familiarity with Python tooling and automated testing
• Experience supporting hardware integration and flight testing
