Collaboration & Continuous Improvement

Collaborate effectively within cross-functional teams Contribute to a positive, high-performance engineering culture Identify opportunities to improve engineering processes, tools, and ways of working Proactively propose and implement improvements that enhance efficiency and quality

Desirable Technical Experience

Experience in one or more of the following would be advantageous:

RF and microwave design from LF through to X-band Design of low-noise amplifiers, receivers, and high-power amplifiers Use of RF simulation and modelling tools (e.g. Microwave Office) PCB design using professional CAD tools (e.g. Altium) Designing solutions with very low SWaP-C constraints RF design for harsh or constrained environments (EMC, vibration, thermal) Transitioning hardware from development into production and qualification Hands-on use of RF test equipment including spectrum analysers, vector analysers, signal generators, power meters, and related instrumentation

Qualifications & Security

Degree-qualified in Electronics Engineering (or equivalent practical experience) Relevant experience in RF or analogue electronic design Due to the nature of the work, applicants must be eligible and willing to undergo UK security clearance
