Senior Space Systems Engineer
Holt Executive
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
