Senior Space Systems Engineer

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 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 ResponsibilitiesLead and support technical activities across mission concept studies, research programmes, and full system development projectsConduct mission analysis, trade studies, and system architecture designManage system and subsystem requirements capture, flow-down, and verificationDevelop and maintain system budgets (mass, power, data, thermal) and performance modelsContribute to strategic development of PNT and telecommunications capabilitiesSupport engagement with institutional and governmental space organisations and stakeholdersProduce technical reports, bid documentation, and engineering recommendations for senior stakeholdersIdentify and manage programme risks, assumptions, dependencies, and technical issuesPerform reliability, availability, and maintainability (RAMS) analysis of system architecturesApply Model-Based Systems Engineering (MBSE) tools and approaches to validate system designs
