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.

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.

NewOrbit Space · Reading

Hands-on precision assembly, integration and test of satellite structures, mechanisms and RF ion thrusters, including torque application, cleanroom operations, MLI installation and building test fixtures and GSE. Also supports AIT campaigns, structural testing and goods-in inspection within a lean team, owning hardware quality, traceability and cleanliness.

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.

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.

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.

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.
