Gregory Martin International Portsmouth £60,000 – £80,000 pa
Consultants work with government and industry clients to analyse problems, capture requirements, create architectures, assess options and make evidence-based recommendations, typically on defence and security research and procurement projects. The role spans the systems engineering lifecycle, from requirements elicitation and V&V to MBSE and trade-off studies, and involves leading technical consulting projects and building client relationships.
Gregory Martin International Chippenham £60,000 – £80,000 pa
Consultants work directly within customer teams to analyse problems, capture requirements, create architectures and assess options using systems engineering methods, then present evidence-based recommendations. Projects typically support defence and security research and procurement, with a focus on space, C4ISTAR and satellite systems, and the role also involves leading bids and building client relationships.
Surrey Satellite Technology Guildford
Lead verification, testing and debugging of imager electronics for optical payloads, covering digital, analogue and mixed-signal circuits from concept through AIT, launch and commissioning. The role involves circuit-level debugging, board-level validation, test automation with Python or TCL, and designing ground support equipment within a collaborative optical payloads team.
Surrey Satellite Technology Guildford
Design, analyse, verify and deliver spacecraft power subsystems and analogue electronics, from battery charge/discharge regulators and DC-DC converters to power distribution and drive electronics. Acts as power subsystem lead on missions, working from concept through launch and operational life alongside technical leads across disciplines.
Matchtech Gloucestershire £450 – £550 pd
Lead supplier management and technical integration for LTPEM fuel cell stack programmes in the aerospace sector, acting as subject matter expert during design reviews and supporting balance-of-plant fluid systems. Analyse test data to assess stack health, degradation and failure indicators, and apply systems engineering to hydrogen-electric propulsion development.
Astroscale Didcot
Design, develop, verify and deploy computer vision algorithms for spacecraft and ground systems, covering space object detection and tracking, 6DoF pose estimation, and subsystem architecture. The role spans hardware-in-the-loop test campaigns, flight software integration, sensor procurement and mentoring junior engineers within a global algorithms and software group.
Holt Executive Oxfordshire £40,000 – £85,000 pa
Design, develop and validate flight dynamics software for defence and space missions, covering orbital mechanics, trajectory design and mission analysis. The role blends algorithm development in Python and MATLAB with requirements capture, verification and Agile Scrum delivery, acting as technical interface with suppliers and operations teams.
NewOrbit Space Reading
Structural analysis of flight hardware for VLEO satellites, covering static, modal, vibration, shock and quasi-static load cases. Builds and validates finite element models, performs hand calculations, and runs vibration and shock qualification test campaigns end-to-end, including instrumentation and model correlation. Works closely with mechanical, thermal, propulsion, systems and AIT teams across the full development lifecycle.
Astroscale Didcot
Develops and maintains flight dynamics software for defence-focused space control missions, specifying algorithms and integrating with an in-house flight dynamics suite. Works in an Agile team with the commercial defence team and Chief Engineer, also supporting bids, customer training and ground segment verification and validation.
NewOrbit Space Reading
Designs satellite mechanical hardware including secondary structures, thermal-control hardware, cable routing and mechanisms, while managing a large shared 3D CAD assembly using top-down design and skeleton models. Maintains PLM data, BOMs and change control, runs clash checks and produces GD&T manufacturing drawings, supporting PDR/CDR reviews, prototyping and environmental testing in a small multidisciplinary team.
