Firmware Engineer - Flight Software

What you will be doing

Neros builds first-person-view drones for the modern battlefield. As a Firmware Engineer on the Flight Software team, you will build the flight-critical firmware that flies the aircraft - flight modes, control algorithms, and the vehicle-side integrations they depend on - across our entire range of products. Your work goes from code to bench to flight test, and what you ship flies in the field.

Responsibilities

• Implement flight modes and control features - position and altitude hold, and the safety and degradation behavior around them
• Port and tune sensors and control algorithms across flight stacks (Betaflight, PX4), preserving flight feel that expert pilots depend on
• Build vehicle-side datalink and payload integrations for new platform variants
• Instrument the vehicle, run bench and flight-test iterations, and debug issues that only reproduce in flight
• Write the unit and integration tests for your firmware, partnering with our Test organization on SITL/HITL and flight-test execution

You should have the following

• Strong embedded C on resource-constrained microcontrollers - you have shipped firmware that runs on real hardware in the field
• Hands-on experience with a flight stack - PX4, Betaflight, or similar - on vehicles that actually flew
• Working grasp of flight-control fundamentals: control loops, filtering, and how sensors (IMU, baro, GPS) become state estimates
• Track record of debugging hardware-coupled problems - failures that only reproduce on the bench or in flight, not in a debugger
• Able to own a problem end to end with light direction - from ambiguous goal to flying firmware
• Test discipline appropriate to safety-relevant firmware

Nice to have

• Datalink, tunneling, or networking-protocol work on embedded systems
• Betaflight internals experience - modes, RC/mixer path, or a maintained fork
• Counter-UAS, radar-guided, or interceptor-adjacent systems exposure or interest
• Estimation depth (EKF/complementary filters, sensor fusion)
• Depth in the PX4 ecosystem - MAVLink, uORB, EKF2, offboard/companion-computer integration, QGroundControl tooling
• You fly - FPV, racing, or fixed-wing RC

US Salary Range
