Saab · Oakley

A two-year graduate programme rotating through four six-month placements in core engineering disciplines, working hands-on with autonomous vehicle technology in the Blue Bear business unit. Graduates rotate as a cohort, are supported by managers and mentors, and may convert to a permanent role based on performance and business needs.

Saab · Fareham

A structured two-year graduate programme rotating through four six-month placements across core engineering disciplines, working hands-on with sub-sea robotics technology at the Saab Seaeye underwater robotics business. Graduates rotate as a cohort, build technical and soft skills, and may convert to a permanent role based on performance and business needs.

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.

Rolls Royce · Solihull

Design and develop software and hardware for electronics test platforms used on aerospace and military products, covering requirements definition, integration testing and validation. The role involves fault-finding at rig and component level, coordinating with project leads and suppliers, and controlling test system hardware design. Programming in C, C#, TestStand, LabVIEW and Python is central.

Rolls Royce · Solihull

Analyse and ensure the structural and mechanical performance of electrical machines, power electronic converters, engine control units and battery systems across their full life cycle. Work with Design, System, Safety, Service and Airworthiness engineers, using simulation tools such as Ansys, NX and LS Dyna to meet company, customer and regulatory requirements.

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.

Open Cosmos Ltd · Didcot

Designs, implements and verifies FPGA logic for satellite subsystems and onboard computing, writing VHDL/Verilog that interfaces with onboard software modules written in Rust. Works with electronics and software engineers on system integration, building test benches and verification frameworks, and supporting hardware-in-the-loop and environmental testing through the full mission lifecycle.

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.

Airbus Defence and Space · Portsmouth

Systems Engineer role focused on TEMPEST and EMC engineering for MOD, Government and SATCOM projects, working on stable long-term programmes with end-to-end products manufactured onsite in clean rooms. Responsibilities include eliciting and validating TEMPEST/EMC requirements, developing systems models and simulations, defining architectures with IS/IT specialists, and discussing requirements with suppliers of hardware, software and firmware.

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.

Expert Employment · Didcot · £38,000 – £75,000 pa

Develop, refine and deploy satellite and terrestrial communication systems spanning infrastructure, field deployment, system architecture and software setup. Work within a 6G future connectivity team on Non-Terrestrial and Terrestrial Ubiquitous Communication concepts, delivering technical projects and consultancy while engaging universities and research centres on satellite-enabled 5G and 6G networks.
