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 of the Senior RF Antenna Design Engineer (Lincoln / Hybrid):

• 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 of the Senior RF Antenna Design Engineer (Lincoln / Hybrid):

• 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, xbpsjku 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
