Flight Software Engineer

Exciting Opportunity: Flight Software Engineer (Perm/Fixed Term)

Our Client, a pioneering leader in the space industry, is shaping the future of space exploration and satellite technology. Known for their cutting-edge approach to satellite development and innovative space solutions, they foster a culture of collaboration, innovation, and technological advancement. Join an organisation committed to pushing the boundaries of what's possible in space and enjoy a supportive environment that values professional growth, diversity, and excellence.
Role Overview:

Due to strategic growth and ongoing projects, Our Client is seeking a talented Flight Software Engineer to lead the development of onboard software for next-generation satellites. This pivotal role offers the chance to directly influence the safety, autonomy, and performance of spacecraft operating in low Earth orbit. Be part of a venture that's transforming satellite capabilities, and contribute to groundbreaking projects with real-world impact.
Key Responsibilities:

• Develop, test, and maintain real-time flight software using programming languages such as C, C++, or Rust on RTOS or Embedded Linux platforms.
• Define interface control documents (ICDs) and create drivers and middleware for hardware interfaces including I2C, SPI, UART, CAN, and SpaceWire.
• Design and implement autonomous behaviour logic, including mode management, sequencing, and fault detection, isolation, and recovery (FDIR).
• Ensure real-time performance through careful management of concurrency, timing, and resource utilisation within stringent constraints.
• Build verification tools and prototypes, including SIL/HIL test harnesses, simulation models, and telemetry analysis tools to validate system integrity and performance.
• Support the deployment of code from review stages through CI/CD pipelines, assisting with integration, launch operations, and secure over-the-air updates.

• Collaborate closely with multidisciplinary teams such as avionics, AOCS, communications, and mission planning to optimise compute, power, thermal, and storage resources.

Essential Skills & Experience:

• Proven experience in developing embedded or real-time systems in C, C++, or Rust within space or high-reliability environments.
• Strong understanding of real-time software principles, including scheduling, interrupt handling, concurrency, and deterministic behaviour.
• Hands-on experience integrating hardware interfaces (I2C, SPI, UART, CAN-FD, GPIO) and practical debugging skills in a lab setting.
• Solid foundation in software engineering best practices: system architecture, static analysis, code reviews, CI/CD pipelines, and system observability.
• Ability to manage projects end-to-end from system requirements and design through implementation, testing, and operational support.

Desirable Skills & Experience:

• Familiarity with spacecraft flight software frameworks, such as cFS, F' or custom lightweight component-based architectures.
• Knowledge of fault management strategies for radiation effects, SEUs, redundancy, and safe-mode protocols.
• Experience with GNC/AOCS systems, including sensor and actuator data pipelines, control algorithms, and estimation filters.
• Exposure to digital twins, simulation environments, and SIL/HIL testing for end-to-end system validation.
• Experience supporting on-orbit operations, including spacecraft commissioning, anomaly handling, telemetry analysis, and OTA updates.

Why Join Our Client?

• Contribute to revolutionary space technologies, including advanced ion propulsion systems and ultra-low Earth orbit satellites that will redefine the future of space communication and observation.
• Take ownership of critical components across the entire satellite lifecycle, from design to deployment and ongoing operation.
• Enjoy a comprehensive package that values your contribution, with options for equity participation, private healthcare, and dental and optical coverage.
• Benefit from a flexible hybrid working model, with one remote working day per week.
• Receive assistance with relocation and visa sponsorship for international candidates wishing to join their innovative team.
