UK Space Jobs

ClearSpace · London

Participate in mission design, mission-level verification and operations for current and future in-orbit servicing and debris removal missions. Model orbits, mission phases and parameters for low- and high-thrust trajectories, define CONOPs and operations plans, and run thermal, radiation, illumination and debris mitigation analyses while interfacing with customers and partners.

ClearSpace · London

Coordinate and execute Assembly, Integration, and Validation activities for current and upcoming space missions, authoring AIV plans, estimating resources, and overseeing daily test operations. Design and maintain test environments including hardware models, harnesses, and IT infrastructure, while driving process improvement and providing technical leadership to the AIV team.

Foundational · London

Lead geodetic processing and analysis of satellite laser ranging data, ensuring it meets international geodetic community standards and becomes trusted products. Contribute to reference frame and Earth orientation products, define data quality standards, and represent the company in the ILRS, IAG and wider geodetic community. Guide data scientists and software engineers on models and algorithms, with opportunities to publish and present at conferences.

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.

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.

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.

Matchtech · Buckinghamshire

Design, simulate and optimise advanced antenna systems for defence and aerospace platforms, covering HF to Ku band, phased arrays and conformal solutions. Work with RF, systems, mechanical and EMC teams, using CST, HFSS, FEKO and ADS, and validate designs through lab and anechoic chamber testing.

Alexander Associates · Cambridgeshire

Hands-on role spanning the full engineering lifecycle of pressurised fluid systems for spacecraft hardware, from architecture, requirements and pressure/flow calculations through component selection, manufacture, integration and testing. Works closely with mechanical, systems and test engineers, and welcomes applicants from aerospace, propulsion, automotive or energy backgrounds rather than requiring space-sector experience.

Holt Executive · Oxfordshire · £60,000 – £94,000 pa

This role involves end-to-end mission operations for satellite systems, including real-time spacecraft control, anomaly resolution, mission planning, and development of operational tools and procedures. The engineer will act as a technical lead, support multiple mission phases, and innovate operations for a growing fleet. It offers broad technical ownership and strategic influence within a collaborative, international team.

Saab · Fareham

Deliver operator and maintainer training on radar and sensor systems at UK and Swedish sites and customer locations worldwide, while developing course material and technical publications. The role combines hands-on fault-finding on customer systems with subject matter expert input into system and software development, requiring regular global travel of up to three weeks per training event.

Eutelsat OneWeb · Forfar

Leads end-to-end system sizing and performance assessment for next-generation satellite communication networks, spanning user terminals, space, ground and network segments. Defines performance budgets, coordinates modelling and simulation, and drives cross-domain trade studies to meet capacity, latency, availability and scalability targets. Interfaces with suppliers and business stakeholders to justify design choices and ensure traceability.

Eutelsat OneWeb · Forfar

Specify and oversee development of mission control and resource management systems for IRIS² and future satellite constellations, covering payload planning, gateway and network configuration. Work spans functional architecture, supplier RFP assessment, trade-offs across subsystems, and integration with IVV teams. Interfaces closely with service and spacecraft operations teams.

CesiumAstro · Cambridge

Performs complex mixed-signal PCB layout in Altium Designer for aerospace electronics, owning dense boards that combine 30 GHz RF, power and digital with advanced stackups. Also manages component libraries, generates symbols and footprints, and maintains schematic, layout and BOM templates while collaborating closely with hardware and mechanical engineers.

CesiumAstro · Cambridge

Owns board-level RF hardware for satellite and aerospace phased array systems, covering schematic design, PCB layout, simulation and lab validation. Works across the full lifecycle from concept and part selection through manufacturing, qualification and in-orbit support, presenting design reviews and contributing to proposals.

Lodestar Space · London · £30,000 – £75,000 pa

Develops avionics software across two specialisms: distributed middleware for onboard compute (high-performance IPC, networking, process supervision, fail-safe OTA updates) or embedded Linux for NVIDIA Jetson flight computers, from board bring-up to kernel tuning and driver development. Works closely with autonomy, AI/ML and hardware teams on fault-tolerant autonomous spacecraft operations.
