RC Fornax is seeking two experienced RF Engineers to work with our defence client in Edinburgh. This role involves leading the design and development of RF subsystems for next-generation surveillance radar, with a focus on antenna or receiver functions. You'll take ownership of key RF hardware components across the full engineering lifecycle and contribute to concept development.
Job Responsibilities
* Lead applied research and feasibility studies, providing RF architecture recommendations for next-gen digital antenna systems.
* Support cross-functional teams (Digital, Systems, Software, Firmware) with RF hardware expertise.
* Own and develop RF PCB assemblies (SRUs), covering the full hardware lifecycle—from requirements and prototyping to testing and production support.
* Create robust designs, maintain documentation and configuration control, and lead PHDP-aligned design reviews.
* Supervise junior engineers within your functional area.
* Collaborate closely with Antenna and Receiver Design Authorities, and wider engineering teams.
* Address integration challenges across current and future systems.
* Deliver manufacturing data packs and support engineering engagement with subcontractors.
Minimum Requirements:
* 5+ years in RF/Microwave hardware engineering at Senior or Principal level.
* Expertise in end-to-end RF subsystem development, including schematic capture, prototyping, layout, and design verification.
* Experience in architecture definition, technical studies, and AR investigations.
* Proficient in RF design tools (e.g. AWR, ADS, SystemVue, Matlab, CST).
* Knowledge of synthesiser (DDS/PLL), downconverter, digitiser, and passive microwave design.
* Skilled in lab testing (spectrum and network analysis).
* Radar, antenna, or receiver development background.
* Experience mentoring junior engineers and leading design reviews.
* Familiar with tools like Mentor for PCB design and strong in documentation and requirements capture.
* Experience with GaAs/GaN MMICs and non-linear circuit simulation.
* Understanding of low phase noise design and measurement.
* Experience in design for manufacture and cost.
* Familiarity with AS9145 or equivalent APQP processes.
Due to the nature of this project, the successful candidate must hold Active SC Clearance and be a sole British national.
