Design and develop analogue and digital electronic systems, including mixed-signal circuits, signal conditioning, filters, amplifiers and power supplies, using microprocessors, ADCs and DACs. Own designs from concept through to volume manufacture, working with RF, software and firmware engineers on integration, testing and troubleshooting across interfaces such as PCIe, USB, Ethernet, CAN, I²C and SPI. The role spans thermal analysis, MTBF and tolerance analysis for telecoms, space, defence and high-altitude platform applications.

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 · Chelmsford

Lead strategic R&D and customer-funded projects in an advanced engineering and manufacturing environment, delivering imaging sensors and subsystems for space science, Earth observation and high-energy physics. Manage cross-functional teams of over ten engineers, owning schedules, budgets, phase-gate reviews and customer relationships, with a strong emphasis on production delivery and financial performance.

NewOrbit Space · Reading

Designs satellite mechanical hardware including secondary structures, thermal-control hardware, cable routing and mechanisms, while managing a large shared 3D CAD assembly using top-down design and skeleton models. Maintains PLM data, BOMs and change control, runs clash checks and produces GD&T manufacturing drawings, supporting PDR/CDR reviews, prototyping and environmental testing in a small multidisciplinary team.

Expert Employment · Aylesbury · £65,000 – £70,000 pa

Lead technical delivery of satellite and terrestrial communication projects, designing end-to-end cellular and satellite systems and developing practical solutions for end users. The role combines hands-on system integration, hardware setup and coding with technical consultancy, working alongside businesses, universities and research partners on emerging 5G, 6G and IoT technologies.

Matchtech · Wimborne

Lead multidisciplinary aerospace engineering projects across the full delivery lifecycle, from customer kick-off through design, manufacture, integration, acceptance and commissioning. Act as primary customer interface, managing scope, cost, schedule, risk and change control while coordinating engineering, production, procurement and quality teams. Distinct for its focus on complex test systems including automated test equipment and avionics test systems.

Proactive · Earley · £60,000 – £65,000 pa

Leading the design of electronic circuits and systems for anti-vibration mounts, avionics racking and illuminated control/display systems used in aerospace, defence and industrial sectors. Involves reviewing customer requirements, preparing bills of materials and cost estimates, managing project risks, running verification and validation, designing test equipment, and mentoring engineers.

Gregory Martin International · Chippenham · £60,000 – £80,000 pa

Consultants work directly within customer teams to analyse problems, capture requirements, create architectures and assess options using systems engineering methods, then present evidence-based recommendations. Projects typically support defence and security research and procurement, with a focus on space, C4ISTAR and satellite systems, and the role also involves leading bids and building client relationships.

Filtronic · High Peak

Designs, simulates and validates RF and mmWave circuits, components and subsystems, running measurements and characterisation on prototypes and production hardware. Works with electronics, mechanical, software and systems engineers to move designs from concept into volume manufacturing, supporting RFQs and customer engagements.

Eutelsat OneWeb · London

Acts as a cornerstone of the Mission Analysis function within an integrated Flight Dynamics team, performing full mission lifecycle analysis from launch to de-orbit, including launch window analysis, maneuver planning, trajectory design and optimisation, orbit determination, constellation analysis, and conjunction assessment. Also supports FDS development and automation, writes engineering specifications and CONOPS documentation, and mentors junior engineers across GEO and LEO programmes.

Eutelsat OneWeb · London

Designs and analyses the physical layer and air interface for next-generation satellite communications and the EU's IRIS2 system. Builds software simulators of user and feeder links (5G, DVB-S2X) to assess channel impairments, RF performance and system-level trade-offs, and sets technical requirements for vendors. Works within the System Engineering team, with a senior role mentoring a second engineer.
