Senior RF Antenna Design Engineer - Electronic Warfare
Location: Lincoln, Lincolnshire (Hybrid)
An exciting opportunity has arisen for a Senior RF Antenna Design Engineer to join a confidential, UK-based defence technology organisation specialising in electronic warfare systems. This role sits within a growing and highly capable RF engineering team developing advanced antenna and RF subsystems across HF to SHF frequencies for complex, mission‑critical applications.
This position is ideal for an experienced, hands‑on RF and antenna engineer who enjoys technical ownership, solving complex electromagnetic challenges, and mentoring junior engineers, while contributing to the development of a strong UK-based R&D capability.
Main Responsibilities
* Design, simulate, and develop RF and microwave antenna systems for electronic warfare applications
* Own antenna and RF design activities from concept through simulation, prototyping, test, and production handover
* Carry out electromagnetic modelling and optimisation using CST, HFSS, Keysight ADS and Microwave Office
* Act as a senior technical contributor on projects, supporting architectural decisions and design reviews
* Collaborate closely with RF, electronics, systems, and mechanical engineers to ensure optimal system integration
* Support development of RF subsystems including filters, amplifiers, switches, and associated control interfaces
* Perform antenna, RF, and EMC testing, correlating lab results with simulation data
* Produce high‑quality technical documentation and contribute to internal and customer‑facing reviews
* Mentor and technically support junior RF and antenna engineers within the team
* Support proposal activity, requirements definition, and early‑stage concept development where required
Requirements
* Proven experience in RF and microwave antenna design for defence, electronic warfare, or other high‑reliability environments
* Strong grounding in electromagnetic theory, RF propagation, and antenna performance metrics
* Hands‑on experience with CST, HFSS, Keysight Microwave Office and ADS
* Practical experience across simulation, prototyping, measurement, and validation
* Experience contributing to or leading technical projects and mentoring junior engineers
* Ability to communicate complex RF concepts clearly within multidisciplinary teams
* British passport holder required due to security clearance requirements
Working Pattern & Benefits
* Full‑time, permanent role
* Hybrid working, with regular onsite presence in Lincoln
* Competitive salary and benefits package
* Opportunity to work on cutting‑edge electronic warfare antenna and RF technology
* Technically driven environment with strong long‑term career progression
