You will:

• Lead the technical delivery of spacecraft systems from concept and architecture through operations and deorbit
• Own system-level architecture, coherence, performance, and reliability across mission phases
• Define, manage, and maintain mission and system requirements with full lifecycle traceability
• Lead system-level verification and validation planning, execution, and technical resolution activities
• Perform system analyses, trade studies, and design optimisation to meet mission and operational objectives
• Develop and improve MBSE methodologies, tools, and systems engineering processes across projects
• Define robust FMECA and Fault Detection, Isolation and Recovery (FDIR) strategies
• Ensure appropriate system margins, resilience, and fault tolerance are embedded into mission designs
• Coordinate multidisciplinary engineering teams to deliver integrated spacecraft solutions
• Act as the systems interface across engineering, AIT, mission management, operations, suppliers, and external partners
• Support bids, customer engagements, reviews, and operational decision-making with systems-level expertise
• Mentor and support junior systems and engineers while promoting engineering best practice across the organisation

What You’ll Bring

• Strong systems engineering capability across the full lifecycle of space missions and spacecraft development
• Deep knowledge of spacecraft subsystems including power, OBC, AOCS, communications, propulsion, and thermal/mechanical systems
• Proficiency with MBSE tools and structured systems engineering methodologies
• Strong understanding of requirements management, verification and validation, margins management, and mission assurance activities
• Knowledge of FMECA, FDIR, CONOPS, and resilient spacecraft system design principles
• Awareness of regulatory and mission constraints including frequency allocation, debris mitigation, export control, and insurance considerations
• Capability to coordinate multidisciplinary engineering teams and manage technical interfaces across complex programmes
