CesiumAstro · Cambridge

Owns end-to-end design of complex electronics modules for satellites and aerospace systems, from architecture and schematic through PCB layout in Altium, analysis, bring-up and production release. Also leads teams of hardware engineers, mentors staff and presents design reviews to customers and executives.

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 · £55,000 – £75,000 pa

Design, lay out, bring up and validate PCBs for high-speed digital avionics on autonomous space platforms, owning subsystem architectures from concept through simulation to hardware testing and on-orbit readiness. Work hands-on with oscilloscopes, logic analysers and harness fabrication, collaborating with mechanical, systems and software teams and supporting EMC, vibration and thermal vacuum qualification.

NewOrbit Space · Reading

Owns functional and system-level testing of spacecraft and verification tracking for each satellite campaign, taking satellites from integrated subsystems to flight-ready, fully verified vehicles. Bridges systems engineering, subsystem teams and AIT functions, turning requirements into test procedures, leading test campaigns and closing out requirements with traceable evidence. Hands-on with EGSE, checkout systems and RF test equipment in a SmallSat environment.

Astroscale · Didcot

Design, develop, verify and deploy computer vision algorithms for spacecraft and ground systems, covering space object detection and tracking, 6DoF pose estimation, and subsystem architecture. The role spans hardware-in-the-loop test campaigns, flight software integration, sensor procurement and mentoring junior engineers within a global algorithms and software group.

Eutelsat OneWeb · London

Provides 24/7 flight dynamics operations support on a shift rota, performing on-console work and real-time mission support from launch to de-orbit. Configures, troubleshoots and monitors orbit determination, maneuver, trajectory and attitude planning software, including collision avoidance planning, and develops operational procedures.

Holt Executive · Oxfordshire · £60,000 – £90,000 pa

This role involves trajectory planning, mission analysis, and developing software for spacecraft operations. You will work on complex orbital missions, including rendezvous, docking, and separation, and support real-time mission phases. The position offers a hybrid and flexible working environment with opportunities for professional growth.

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.

NewOrbit Space · Reading

Lead a team building the on-board flight-software stack for very low Earth orbit satellites, covering real-time control flows, autonomy, mode management and FDIR. You'll design and test deterministic C/C++ services on RTOS or Embedded Linux, integrate subsystems over I2C/SPI/CAN/SpaceWire, and take software from simulation through launch to on-orbit operations with over-the-air updates.

Expert Employment · Aylesbury · £38,000 – £42,000 pa

Design, develop and assemble test equipment and ground support systems for rocket engines and propulsion systems within a Test Group. Duties include developing test procedures, carrying out testing, risk assessments and safety reviews, analysing test data and supporting hot-fire testing and new product development. Hands-on mechanical fitting work in test facilities, cleanrooms and outdoor environments.
