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

Consultants work with government and industry clients to analyse problems, capture requirements, create architectures, assess options and make evidence-based recommendations, typically on defence and security research and procurement projects. The role spans the systems engineering lifecycle, from requirements elicitation and V&V to MBSE and trade-off studies, and involves leading technical consulting projects and building client relationships.

Foundational · London

Own the laser subsystem in autonomous satellite laser ranging stations, from specifying and qualifying pulsed laser sources with suppliers to integrating beam delivery, cooling, power, control and safety interlocks. Characterise performance with test rigs and improve reliability so lasers run unattended at remote sites, working alongside optics, software and astrodynamics specialists.

Foundational · London

Designs the electronics that run autonomous satellite laser ranging stations, covering control, power and sensing plus interfaces linking lasers, detectors, telescopes and computers. Involves PCB design and bring-up, power distribution for remote sites, sensor integration, component selection and supplier management, with lab debugging and field support. Part of a small London team spanning optics, lasers, software and astrodynamics.

Astroscale · Didcot

Develops and maintains flight dynamics software for defence-focused space control missions, specifying algorithms and integrating with an in-house flight dynamics suite. Works in an Agile team with the commercial defence team and Chief Engineer, also supporting bids, customer training and ground segment verification and validation.

Astroscale · Didcot

Lead a team of 6-8 systems engineers who act as the technical linchpin for Astroscale UK's space systems projects across the product lifecycle. The role combines hands-on mission concept definition, requirements derivation, trade-off analysis and system architecture with line management, task planning, appraisals and recruitment. Distinct for its blend of deep space systems engineering and people leadership in an on-orbit servicing context.

Filtronic · Cambridge

Designs, develops and integrates embedded software and firmware for advanced RF and communications products across the full lifecycle, from concept to volume manufacture. Strong focus on Zephyr-based development alongside embedded Linux, Yocto, bare-metal firmware, networking and secure communications, working closely with RF, FPGA, hardware and systems engineers.

Filtronic · Cambridge

Lead the design, simulation and development of RF and mmWave circuits, components and subsystems, including system analysis, performance optimisation and troubleshooting.
