Acts as the interface between the Flight Software and GNC teams across current and future missions.

ClearSpace · London

Act as technical authority for spacecraft propulsion design within the Mechanical, Thermal and Propulsion team, owning the propulsion architecture across the mission lifecycle. Lead concept definition, system-level trade-offs, budgets, requirements and verification, with potential to coordinate the MTP domains on a mission. Involves mentoring engineers and engaging customers, suppliers and institutional stakeholders.

Foundational · London

Runs grant and contract bids for space agencies and innovation bodies, tracking funding calls and managing submissions end to end. Writes non-technical sections on management, finance, impact and commercialisation, builds bid budgets and coordinates consortium partners. Also handles post-award reporting and compliance, freeing engineers to focus on technical content.

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.

Foundational · London

Develops and improves automated precision orbit determination pipelines and flight dynamics tooling for the Origin platform, including force models, measurement corrections and spacecraft modelling. Builds orbit prediction and ephemeris products, validates data products and supports customers using orbit products. Works on-site in central London within a small team of engineers and scientists.

Astroscale · Didcot

Develops and operates in-house flight dynamics software for orbital manoeuvres, rendezvous, docking and collision avoidance across multiple mission phases. Interfaces with GNC, ground segment and contractor teams, supports 24/7 shift operations, and works with MATLAB, C++ and Python in a hybrid Harwell-based team.

Filtronic · Stockton-on-Tees

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 · 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.

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

Lead major consulting projects delivering systems engineering expertise to defence, energy and health clients, covering requirements, architecture, MBSE and V&V. Combines team leadership, technical oversight, mentoring and business development including bids and client relationships, with a strong defence background required.

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

Lead major consulting projects across defence, energy and health, delivering requirements engineering, architecture development, MBSE and integration, verification and validation. Combines team leadership and mentoring with client delivery, bid input and business development, acting as a subject matter expert for UK MOD and defence primes.

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.
