Spire · Glasgow

Builds and maintains the tooling and infrastructure behind satellite software development, including advanced test frameworks for virtual and bare-metal hardware, an automated in-orbit update pipeline, and a next-generation software framework. Works in a small, self-directed team within a 150+ person engineering org, spanning embedded systems, GitOps, and CI/CD.

ClearSpace · London

Lead the Guidance, Navigation and Control architecture for a space mission, defining subsystem requirements, simulator and test specifications, and managing the GNC engineering team. The role involves fault-tolerant algorithm design, rendezvous and pose estimation sensors, trajectory design and hardware integration, interfacing with system and robotic architects. Distinct for its focus on in-orbit servicing and space debris removal.

ClearSpace · London

Develops, integrates and validates GNC software within spacecraft flight software, spanning requirements, design, implementation and verification. Builds simulation environments, software development infrastructure and automated verification frameworks, and runs closed-loop GNC tests on FlatSat and representative test benches. Acts as the interface between the Flight Software and GNC teams across current and future missions.

Foundational · London

Owns optical design across laser ranging stations, optical tracking systems and retroreflector products, from requirements and tolerancing through to verified hardware. Runs trade studies with suppliers on telescopes, windows, coatings and filters, and mentors graduate and junior engineers. Hands-on lab work includes alignment, metrology and interferometry.

Foundational · London

Own the fit-out and day-to-day running of a new London facility with workshop, labs and cleanroom, covering health, safety and environmental compliance, maintenance, security, budgets and suppliers. Works closely with landlords, contractors and engineers at an early-stage spacetech company.

Astroscale · Didcot

Develops and operates in-house flight dynamics software for orbital manoeuvres, rendezvous, docking and collision avoidance across multiple mission phases. Interfaces with GNC, ground segment and contractor teams, supports 24/7 shift operations, and works with MATLAB, C++ and Python in a hybrid Harwell-based team.

Filtronic · Cambridge

Lead the design, simulation and development of RF and mmWave circuits, components and subsystems, including system analysis, performance optimisation and troubleshooting. Carry out measurements, characterisation and validation of prototypes and production hardware, and support the transition from concept through prototyping into volume manufacturing. Works closely with electronics, mechanical, software and systems engineers, and contributes technical input to RFQs, proposals and customer engagements.

Filtronic · Stockton-on-Tees

Design and develop analogue and digital electronic systems, including mixed-signal circuits, signal conditioning, filters, amplifiers and power supplies, using microprocessors, ADCs and DACs. Own designs from concept through to volume manufacture, working with RF, software and firmware engineers on integration, testing and troubleshooting across interfaces such as PCIe, USB, Ethernet, CAN, I²C and SPI. The role spans thermal analysis, MTBF and tolerance analysis for telecoms, space, defence and high-altitude platform applications.

Expert Employment · Aylesbury · £40,000 – £45,000 pa

Design and improve production tooling and fixtures for a specialist aerospace and engineering environment. Use CAD (Creo) to create detailed engineering drawings, develop prototypes, test and validate new tooling, and troubleshoot issues. Work closely with manufacturing and process engineers to improve production quality, efficiency and costs while ensuring compliance with safety and quality standards.

Holt Executive · Chelmsford

Lead strategic R&D and customer-funded projects in an advanced engineering and manufacturing environment, delivering imaging sensors and subsystems for space science, Earth observation and high-energy physics. Manage cross-functional teams of over ten engineers, owning schedules, budgets, phase-gate reviews and customer relationships, with a strong emphasis on production delivery and financial performance.

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.

Expert Employment · Aylesbury · £65,000 – £70,000 pa

Lead technical delivery of satellite and terrestrial communication projects, designing end-to-end cellular and satellite systems and developing practical solutions for end users. The role combines hands-on system integration, hardware setup and coding with technical consultancy, working alongside businesses, universities and research partners on emerging 5G, 6G and IoT technologies.

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.

Eutelsat OneWeb · London

Acts as a cornerstone of the Mission Analysis function within an integrated Flight Dynamics team, performing full mission lifecycle analysis from launch to de-orbit, including launch window analysis, maneuver planning, trajectory design and optimisation, orbit determination, constellation analysis, and conjunction assessment. Also supports FDS development and automation, writes engineering specifications and CONOPS documentation, and mentors junior engineers across GEO and LEO programmes.
