Senior Space Systems Engineer
About the Role
We are seeking a highly experienced Senior Space Systems Engineer to support the design, development, and integration of complex space-based systems across telecommunications and positioning, navigation, and timing (PNT) domains.
This is a senior-level opportunity within a strategic engineering team focused on delivering high-performance, resilient global communication and navigation capabilities for mission-critical users. The role spans early concept studies through to full system development and delivery.
You will be part of a multidisciplinary engineering environment, contributing to the growth of advanced systems engineering capability while helping shape next-generation space-enabled services.
Key Responsibilities
- Lead and support technical activities across:
- Mission concept studies
- Research programmes
- Full system development projects
- Conduct mission analysis, trade studies, and system architecture design
- Manage system and subsystem requirements capture, flow-down, and verification
- Develop and maintain system budgets (mass, power, data, thermal) and performance models
- Contribute to the strategic development of PNT and telecommunications capabilities
- Support engagement with institutional and governmental space organisations and stakeholders
- Produce:
- Technical reports
- Bid documentation
- Engineering recommendations for senior stakeholders
- Identify and manage:
- Programme risks, assumptions, dependencies, and technical issues
- Perform reliability, availability, and maintainability (RAMS) analysis of system architectures
- Apply Model-Based Systems Engineering (MBSE) tools and approaches to validate system designs
