Durham, Durham, United Kingdom IC Resources Full time £60,000 - £120,000 per year

I'm working with a long-standing client in the high-frequency communications space. They specialise in RF and mmWave technologies for advanced telecoms, space, defence and next-gen sensing applications. Their engineering team develops high-performance subsystems such as SSPAs, filters and transceivers, with a strong focus on precision, manufacturability and reliability.

They are looking to add a Senior RF Design Engineer who can take ownership of RF/mmW design work across sub-circuits, sub-modules and full systems. As a Senior RF Design Engineer, you'll work through the entire lifecycle — specification, simulation, validation, and handover into production — ensuring designs meet performance, quality and cost targets.

  • IC/MMIC component selection and vendor interaction

  • Collaboration with mechanical and PCB teams on electromechanical concepts and high-frequency layouts

  • System line-up analysis, MTBF, thermal and derating work
  • Production of design documentation: logbooks, data packs, peer reviews and release documentation
  • Preparation and review of NPI/tollgate materials
  • Leading and contributing to design reviews, proactively identifying risk areas
  • Verification and validation: test specs, test reporting, reliability evaluation
  • Maintaining compliance matrices and evidence trails
  • Production-support problem solving, fault finding and defining diagnostic procedures

Requirements

  • Degree in RF, Electronics, Communications or similar
  • Hands-on experience with tools such as Microwave Office, CST, EMPro, ADS
  • Strong background in RF/microwave system design, yield/tolerance analysis and DFM
  • Experience in transceiver design highly beneficial

Benefits

  • Pension scheme
  • Life assurance
  • Annual leave package
  • Hybrid / work-from-home flexibility
  • Training & development budget
