UK Space Jobs

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.

ClearSpace · London

Act as technical authority for spacecraft propulsion design within the Mechanical, Thermal and Propulsion team, owning the propulsion architecture across the mission lifecycle. Lead concept definition, system-level trade-offs, budgets, requirements and verification, with potential to coordinate the MTP domains on a mission. Involves mentoring engineers and engaging customers, suppliers and institutional stakeholders.

Foundational · London

Runs grant and contract bids for space agencies and innovation bodies, tracking funding calls and managing submissions end to end. Writes non-technical sections on management, finance, impact and commercialisation, builds bid budgets and coordinates consortium partners. Also handles post-award reporting and compliance, freeing engineers to focus on technical content.

Foundational · London

Develops and improves automated precision orbit determination pipelines and flight dynamics tooling for the Origin platform, including force models, measurement corrections and spacecraft modelling. Builds orbit prediction and ephemeris products, validates data products and supports customers using orbit products. Works on-site in central London within a small team of engineers and scientists.

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.

Filtronic · High Peak

Designs, simulates and validates RF and mmWave circuits, components and subsystems, running measurements and characterisation on prototypes and production hardware. Works with electronics, mechanical, software and systems engineers to move designs from concept into volume manufacturing, supporting RFQs and customer engagements.

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, implement and verify RF payload solutions for satellite missions, covering system-level performance analysis of communications, radar and SIGINT payloads. The role spans hardware specification for transmitters, receivers and antennas, signal processing, tool development, and payload verification through environmental test and in-orbit commissioning. It also includes work package management, budget and schedule planning, bid input and presenting technical progress to stakeholders.

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.

Ernest Gordon Recruitment · Newry · £45,000 – £50,000 pa

Day-to-day, you'll work in the quality department of an aerospace manufacturer, overseeing inspection activity, liaising with customers and production lines, supporting auditing teams and driving continuous improvement to ensure products meet high standards before distribution. The role is days-based, Monday to Friday, with mentoring and in-house training aimed at progression into senior positions.

SatVu · London

An open speculative application for a satellite earth observation company, inviting exceptional people to reach out even without a specific advertised role. The company hires across technical engineering, data science, thermal science, front and back end engineering, UI/UX, geospatial analysis, cloud/DevOps, sales, and office, HR and PR functions.

Expert Employment · Aylesbury · £35,000 – £40,000 pa

This role involves the precise assembly, integration, and testing of space-certified aerospace components, including valves and thrusters. Responsibilities include using specialized equipment for leak detection, material joining processes like TIG welding, and maintaining cleanroom facilities.

Aalyria · London

Join a team building laser communications and temporospatial software-defined networking platforms for aerospace, working on satellite and airborne mesh networks plus cislunar and deep-space communications. The role centres on orchestrating and managing planetary mesh networks across any radio or optical spectrum, orbit, or hardware spanning land, sea, air and space.

CesiumAstro · Milton Keynes

Designs and implements high-speed DSP algorithms for satellite and aerospace communication systems, including filters, equalisers, timing/carrier recovery loops and FFT engines. Builds floating- and fixed-point models in MATLAB or Python to verify VHDL hardware realisations, modelling channel impairments such as noise, Doppler and multipath.
