Flight Firmware Engineer

Welcome to Matter, where we are building the future of vision AI: pairing a world-first sensor that sees molecular chemistry, temperature, and 3D shape with a Large World Model that will be the most powerful intelligence engine for the physical world. This system doesn't just see what something looks like; it understands everything from a single pixel. We call this Superintelligent Vision.

Our team has delivered technologies to Mars for NASA/JPL, designed advanced sensors for U.S. Defense, and frontier artificial intelligence systems. We are now building the next generation of space- and airborne-based sensing systems.

Matter is hiring a Flight Firmware Engineer to develop the low-level software that connects our sensing hardware to reliable airborne and spaceborne operations. This role will work closely with payload electronics, flight software, systems, test, and operations through board bring-up, integration, qualification, and flight.

• Develop and maintain embedded firmware, device drivers, and hardware-control interfaces for sensing payload electronics.

• Support board bring-up, peripheral integration, command and telemetry paths, timing, and fault handling.

• Translate system and hardware requirements into testable firmware behavior and clear interfaces with flight software.

• Build unit, integration, and hardware-in-the-loop tests and support environmental and flight qualification activities.

• Diagnose issues using logs, instrumentation, and test data; document root causes and implement reliable corrective actions.

• Experience developing and debugging embedded software close to hardware.

• Strong understanding of processors, peripherals, communication interfaces, timing, memory, and real-time behavior.

• Hands-on experience with board bring-up, laboratory debugging, automated testing, and version-controlled software development.

• Ability to work across firmware, electronics, flight software, systems engineering, and test disciplines.

• Experience with aerospace, avionics, robotics, sensing, or other mission-critical embedded systems.

• Experience with real-time operating environments, programmable logic interfaces, or high-throughput sensor data paths.

• Familiarity with environmental qualification, fault-tolerant design, and flight anomaly response.

• Firmware provides stable, observable control of payload hardware through integration and qualification.

• Interfaces with electronics and flight software are documented, tested, and resilient to expected faults.

• Hardware issues are diagnosed quickly and firmware releases are traceable and ready for flight operations.

This role is based in El Segundo, CA, and requires onsite work.
