Flight-Critical Avionics Software Engineer

Furientis; Los Angeles (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Furientis in Los Angeles, CA seeks 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, owning mission-critical avionics software interfacing with flight hardware and operational systems.

This role offers broad technical ownership, rapid iteration, and involvement from concept to flight. On-site only, with monthly travel for test events.

Qualifications

• 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 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.

Responsibilities

• 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.
