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.

Expert Employment · Aylesbury · £40,000 – £45,000 pa

Design and improve production tooling and fixtures for a specialist aerospace and engineering environment. Use CAD (Creo) to create detailed engineering drawings, develop prototypes, test and validate new tooling, and troubleshoot issues. Work closely with manufacturing and process engineers to improve production quality, efficiency and costs while ensuring compliance with safety and quality standards.

Holt Executive · Oxfordshire · £40,000 – £70,000 pa

Contribute across the GNC development lifecycle for complex satellite missions, from requirements, architectures and FDIR to V&V strategies. Involves integrating GNC algorithms, computer vision and hardware, plus flight software architecture, trade-offs and on-orbit operations support. Distinct for its focus on rendezvous, proximity operations and spacecraft capture systems.

Filtronic · Stockton-on-Tees

Design and lay out advanced MMICs in GaAs, GaN and InP for microwave and millimetre-wave products operating from 37GHz to 115GHz, covering LNAs, PAs, converters, attenuators and multipliers. The role spans simulation, verification, thermal and reliability analysis, foundry liaison and lab characterisation, with scope to influence technology direction and mentor engineers.

Surrey Satellite Technology · Guildford

Oversees the technical execution, cost, budget and delivery of mechanisms project solutions, ensuring adherence to risk profiles and design policies. Leads a team of electro-mechanical engineers, managing work packages, resource conflicts and capability development while collaborating with Mechanism Experts and Project Managers. Includes hands-on support for debugging mechanism hardware and some project and design work.

Surrey Satellite Technology · Guildford

Lead the power subsystem on spacecraft missions from concept through launch and operations, owning requirements flow-down, design, analysis, verification and delivery. Manages work packages including budget, schedule and risk, interfacing with technical leads and customers, and supports bids and future product development.
