About the role

Key responsibilities & impact

Own the on-board flight-software stack – design, implement and test real-time Rust/C/C++ on RTOS or Embedded Linux.
Integrate subsystems end-to-end – define ICDs and build drivers/middleware over I2C/SPI/UART/CAN(-FD)/SpaceWire (as applicable).
Build spacecraft behaviors & autonomy – implement mode management, sequencing, and autonomous FDIR for safe and productive operations.
Deliver reliable real-time performance – manage concurrency, timing, CPU/memory budgets, and observability under tight constraints.
Build verification infrastructure – prototypes, SIL/HIL test harnesses, simulations, and telemetry analysis tooling to validate designs early.
Ship code from review to orbit – push through CI/CD, support integration and launch ops, and deliver secure over-the-air updates.
Work across disciplines – collaborate with avionics, AOCS, comms and mission teams to trade compute, power, thermal, storage and link budgets.

Requirements

What you’ll need

Proven experience in building production embedded or real-time systems in C/C++ and/or Rust on RTOS or Embedded Linux for space systems.
Strong grasp of real-time software: scheduling, interrupts, concurrency primitives, determinism, and designing for constrained CPU/memory.
Proven ability to build reliable, testable systems: unit/integration testing, simulation-first development, HIL validation, and disciplined debugging.
Hands-on experience integrating with hardware via common interfaces (I2C, SPI, UART, CAN(-FD), GPIO, etc.) and practical lab debugging.
Solid software engineering fundamentals: architecture, code review, static analysis, CI/CD, configuration management, and observability/logging.
Ability to own systems end-to-end: from requirements and design through implementation, verification, operations support, and iterative improvement.
