Embedded Software Engineer (Space) - Berkshire

You'll design and implement robust flight-software services on RTOS or Embedded Linux-turning mission requirements into deterministic, testable software-then take it from simulation all the way to launch and on-orbit operations.

Key Responsibilities

• 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.

Fundamental Requirements

• 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.

Nice-to-haves

• Experience with spacecraft flight software frameworks (e.g., cFS, F', or building lightweight component-based equivalents).

• Familiarity with autonomy and fault management patterns for radiation/SEUs, watchdog strategies, redundancy, and safe-mode design.

• GNC/AOCS-adjacent experience: sensor/actuator pipelines, control-loop integration, estimation/filters, timing analysis.

• Digital-twin / simulator / SIL-HIL experience for end-to-end behavior validation and regression testing.

• On-orbit operations know-how: commissioning flows, anomaly response, telemetry triage, and OTA update strategies.
