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 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
