System Architect Space Missions, London

Location: London, UK or Luxembourg Hybrid

Join a world-class engineering team at the forefront of the sustainable space revolution. We are developing groundbreaking missions that redefine how we interact with assets in orbit. We are looking for a seasoned System Architect to serve as the technical authority for one of our primary mission developments, ensuring technical success from conception through to in-orbit operations.

This is a senior leadership position for a technical expert who can balance deep spacecraft engineering knowledge with project management and stakeholder diplomacy. You will lead multidisciplinary teams to deliver end-to-end mission segments, including space, ground, and launch.

• Technical Authority: Lead the technical delivery of end-to-end missions and manage the technical baseline, including change impact assessments.
• Requirements & Architecture: Derive technical and business requirements to define overall mission architectures.
• Interface Management: Oversee critical interfaces between subsystems, ground segments, and launch vehicles.
• Risk & Budget: Take ownership of the technical risk register and system-level budgets (mass, power, link, etc.).
• Subcontractor Oversight: Monitor and control technical work performed by external partners to ensure contractual compliance.
• Operational Support: Provide expertise during design reviews, AIT (Assembly, Integration, and Test), and in-orbit operations including LEOP.

• 10+ years in the spacecraft industry, with at least 5 years in technical leadership.
• Comprehensive knowledge of the full space program lifecycle (Proposal → Design → Launch → Operations).
• Deep expertise in at least three core areas: e.g., AOCS, Avionics, Propulsion, Power, FDIR, or AIT.
• Demonstrated experience with LEO, MEO, or GEO spacecraft systems.
• A proven track record of successfully delivering complex space development programs.
• Excellent communication skills, with experience managing relationships with commercial customers and major institutions (e.g., ESA/UKSA).
