What You'll Be Doing

You’ll take ownership of software design from concept to flight. That means defining architectures, implementing and verifying embedded code, and leading reviews to ensure compliance with space standards.

You will:

• Lead the design, architecture, and implementation of flight software for new satellite platforms and missions.
• Define software interfaces, patterns, and frameworks for onboard and ground systems using Rust, C, and C++.
• Oversee system-level integration and testing of flight software across multiple missions.
• Implement and review mission-critical features such as fault tolerance, safe modes, and autonomous recovery.
• Mentor junior engineers, ensuring best practices in coding standards, version control, CI/CD, and documentation.
• Drive design and code reviews, ensuring compliance with ECSS, DO-178C, and Open Cosmos software assurance standards.
• Collaborate with hardware, systems, and operations teams to optimise performance and ensure mission readiness.

What You’ll Bring

• Deep expertise in Rust, with proficiency in C/C++ and embedded systems.
• Familiarity with space protocols (CCSDS, telemetry/telecommand).
• Strong grasp of software assurance, fault detection, and recovery design.
• Experience with CI/CD, testing automation, and configuration management.
• A structured yet creative approach, balancing precision with problem-solving.

For this role you can be based in Harwell in UK, Barcelona in Spain or Athens, Greece.

To apply, you must have the legal right to work in your chosen location.
