Description: 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 Responsibilities
  • Lead and support technical activities across mission concept studies, research programmes, and 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 strategic development of PNT and telecommunications capabilities
  • Support engagement with institutional and governmental space organisations and stakeholders
  • Produce technical reports, bid documentation, and 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

Experience Required
  • Degree-qualified in Physics, Engineering, Mathematics, or a related numerate discipline (or equivalent experience)
  • Significant experience in systems engineering or system architecture roles within the space industry or a related sector
  • Strong understanding of spacecraft systems, space mission operations, and spacecraft development (including AIT processes)
  • Experience with system modelling tools such as STK, MATLAB, and MBSE platforms (e.g. Enterprise Architect)
  • Knowledge of orbit determination techniques and space system analysis
  • Strong understanding of project management and financial modelling principles
  • Excellent communication skills, including technical writing and stakeholder presentations at all levels
  • Membership of a professional engineering institution (e.g. INCOSE or equivalent) is desirable

Desirable Experience
  • Knowledge of PNT systems, GNSS, satellite-based augmentation systems, or time transfer techniques
  • Experience with advanced space system operations and analysis methodologies
  • Familiarity with alternative timing systems beyond GNSS-based solutions
  • Exposure to large-scale international space or government programmes
