You'll join a small embedded team where your work spans the full lifecycle: board bring-up, driver and application development, hardware/software debugging, and supporting reliable firmware updates for hardware in the field and on orbit. This is a high-ownership role: after ramp-up, you'll be the standing owner of a meaningful piece of our embedded software stack., * Own embedded software for spacecraft subsystems from concept through on-orbit operations * Design, develop, and debug real-time embedded software for microcontroller-based avionics boards in both FreeRTOS and bare-metal environments * Implement low-level drivers, peripheral interfaces, and real-time control loops for power distribution, thermal control, sensors, and actuators * Build and maintain software supporting board bring-up as well as safe, robust in-field and in-flight firmware update mechanisms * Integrate with and develop robust command and telemetry infrastructure * Work deeply at the software-to-hardware boundary: read schematics, understand pinouts, drive physical hardware, and diagnose issues that could originate in firmware or hardware * Build robust, fault-tolerant systems with attention to reliability, determinism, and performance in constrained environments * Support board bring-up, hardware integration, and hardware-in-the-loop (HITL) testing * Develop automated test frameworks and validation tooling for embedded systems * Collaborate closely with electrical, avionics, and software teams to define system architecture and interfaces * Investigate anomalies, perform root cause analysis, and implement fixes across hardware/software boundaries * Contribute to system-level design, including fault detection, isolation, and recovery (FDIR) strategies
