UK Space Jobs

Flarebright · Bicester · £39,000 – £49,000 pa

Contributes across the full development lifecycle, from concept and algorithm design to system integration, testing and troubleshooting of safety-critical navigation and autonomy software in C++. Works with a multidisciplinary team on real-time embedded systems, hardware/software-in-the-loop testing and flight test activities, producing design documentation and test reports.

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.

Honeywell · Basingstoke

Internship supporting a Materials team within Honeywell Aerospace's Avionics Technology business in Basingstoke, gaining exposure to supply chain operations. The role sits alongside a materials management function tied to navigation, guidance and communication products.

ClearSpace · London

Supports the technical development of spacecraft data handling and avionics systems, covering architecture, interfaces and system-level integration across the full mission lifecycle from concept and requirements through design, AIT, launch and in-orbit commissioning. Works closely with subsystem, software and systems engineers, and acts as technical point of contact with project teams, customers and subcontractors.

ClearSpace · London

Support the technical development of spacecraft across the full mission lifecycle, from concept and requirements definition through design, AIT, launch and in-orbit commissioning. Focus on avionics architecture, interfaces and system-level integration, acting as technical point of contact with customers and subcontractors while maintaining electrical budgets and parametric models.

Orion Electrotech · Wiltshire

Lead propulsion system development from concept through qualification and in-service support, integrating gas turbine, rocket, reciprocating, battery-electric and emerging technologies. Own requirements, architecture, interfaces and configuration control while leading testing programmes and mentoring engineers across multidisciplinary teams.

Spire · Glasgow

Owns the full lifecycle of spacecraft GNC hardware, from selecting and qualifying flight sensors and actuators to maintaining 6-DOF simulation models and avionics peripherals. Works hands-on in lab and manufacturing settings with cross-functional hardware, software and systems teams, in a design-to-launch cycle measured in weeks rather than years.

Orion Electrotech · Marlborough · £40,000 – £45,000 pa

Design-focused role developing advanced mechanical and engine-related systems for aerospace and defence programmes, taking concepts from initial design through testing, validation and implementation. Involves structural, thermal and fluid dynamic analysis using CAD and simulation tools, plus collaboration with systems and avionics teams. Hybrid working near Marlborough.

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.

ClearSpace · London

Supports the full technical development of satellite missions, from early concept and requirements through launch and in-orbit commissioning. Coordinates system-level activities, manages interfaces and maintains the system baseline and engineering documentation across subsystems. Works on current missions and future projects within the Systems Engineering Team.

ClearSpace · London

Owns the spacecraft thermal architecture across all mission phases, defining control strategies, thermal budgets and hardware such as MLI, radiators, heat pipes and heaters. Leads thermal modelling in ESATAN-TMS, verification and TVAC testing, and may coordinate the Mechanical, Thermal and Propulsion domains on a mission. Acts as technical authority liaising with customers, suppliers and partners while mentoring thermal engineers.
