Flight Software Architect

At Clear Space, we believe in reusability, in affordability driving disruption, and that no progress is real unless it is sustainable.

Our company was founded in 2018 out of the realization that in-orbit servicing and space debris removal are vital services for the future of space exploration and operations. Today Clear Space has assembled an expert engineering team and is leading the way toward sustainable space operations. From a garage in Switzerland, we now operate across UK and Europe, and are working with world-leading institutions and companies to bring our dream of a sustainable space ecosystem to life.

We are looking for a Flight Software Architect to join our UK office who will work on both our current missions and future projects.

The Flight Software Architect reports to the Flight Software & AIV team lead and is responsible for defining, maintaining, and evolving Clear Space Flight Software (FSW) architecture and technical roadmap, and for ensuring consistent execution across projects.

At discipline level, you will support projects in the definition and implementation of the FSW roadmap (architecture baseline, key design decisions, reviews, standards, and reuse). At project level, you will act as Software Subsystem Lead on selected projects, owning software design and system specification and supporting delivery commitments (scope, cost, schedule, and quality).

• Strong software architecture and design skills, including requirements-driven development and design reviews
• Ability to work hands-on when needed (development and validation of key software components)
• MSc Degree in Software, Electronics, Aerospace, Physics or similar
• Team player attitude and good communication skills
• Innovative and rigorous
• Capacity to have both a helicopter view of the FSW matters and to dive into complex detailed technical topics
• Team leadership and mentoring
• Experience delivering software in a project context (planning, cost/schedule awareness, supplier coordination)

• Real-time embedded development (e.g., C/C++, RTOS, low-level interfaces)
• Verification tooling and automation (e.g., unit/integration testing, CI, scripting such as Python)
• Space software context (e.g., ECSS processes, AIV/AIT interfaces, on-board software constraints)
