UK Space Jobs

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

Own cloud infrastructure, CI/CD and infrastructure as code while building monitoring, logging and alerting across a satellite laser ranging platform and its remote station fleet. Lead incident response, secure remote access and software updates, and strengthen security posture for a small London-based spacetech team.

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.

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.

Foundational · London

Builds the data platform that ingests, processes and serves satellite laser ranging measurements, from station ingest pipelines to customer APIs. Involves designing time-series data models, cloud infrastructure with Docker and Kubernetes, and working with geodesy and orbit determination engineers. Based on-site in London at an early-stage spacetech company.

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.

Foundational · London

You will act as the technical voice in sales conversations, running discovery calls and demos with satellite operators and scoping tracking tiers, data products and retroreflector solutions. The role also involves answering technical requirements in RFPs, supporting customers integrating retroreflectors onto spacecraft, and feeding customer needs back to product and engineering. It sits within a small London team of engineers and scientists working on satellite laser ranging.

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.

Foundational · London

Coordinates international freight of high-value, sensitive station hardware from suppliers to London and onward to sites across four continents. Handles customs documentation, commodity codes, duty and import VAT, temporary-import processes such as ATA Carnets, and export compliance classifications and licences, while tracking inventory and assets and managing freight forwarders, customs brokers and host sites.

Foundational · London

Build and maintain both frontend and backend of a real-time space-domain SaaS platform, working across Python, React, FastAPI, MongoDB, AWS, Terraform and Airflow. The role also covers DevOps, CI/CD via GitLab and close collaboration with product, with genuine ownership as an early team member in a small spacetech startup.

Foundational · London

Owns the full lifecycle of Satellite Laser Ranging and Space Debris Laser Ranging systems, from radiometric link-budget modelling and optical bench assembly to time-of-flight data processing and orbital determination. Leads deployment and site acceptance testing of optical ground stations and acts as laser safety subject matter expert under UK/EU standards. Requires Python instrument control, Linux, high-precision timing hardware and LiDAR/SLR signal processing expertise.
