About the Role:

We are seeking a highly skilled and motivated RF Engineers to join Venn’s client’s growing technical team. This role offers a unique opportunity to contribute to advanced RF systems across a variety of domains, including antenna design, RF circuit development, geolocation, and electronic warfare. You will be working in a fast-paced R&D environment on cutting-edge projects involving communication systems, sensor integration, and new defence technologies.

Key Responsibilities:

• Design and optimise antennas (directional and omnidirectional) across frequency ranges including VHF, UHF, L-band, S-band, and C-band.
• Perform electromagnetic (EM) simulations using industry tools such as CST, HFSS, FEKO, or Altair to evaluate gain, radiation patterns, impedance matching, and polarisation
• Model RF propagation in complex environments
• Develop and test RF circuits, including filters, amplifiers, mixers, couplers, and attenuators
• Conduct testing and validation using VNAs, spectrum analysers, signal generators, oscilloscopes, and software-defined radios (SDRs)
• Apply RF direction-finding and geolocation techniques such as Angle of Arrival (AOA), Time Difference of Arrival (TDoA), and Multilateration (MLAT)
• Support the design and evaluation of Electronic Warfare (EW) and Counter-UAS systems, including waveform generation and GPS spoofing countermeasures
• Ensure all developments adhere to UK export controls and relevant RF emission legislation
• Produce clear technical documentation, test plans, and compliance reports
• Participate in design reviews and cross-functional technical discussions

Essential Experience & Skills:

• Integration of RF payloads
• RF signature analysis and evaluation of communication link vulnerabilities.
• Digital Signal Processing (DSP) skills using MATLAB, Python (NumPy), or C/C++.
• Experience with SDR platforms (e.g., Ettus USRP, HackRF, BladeRF, LimeSDR) and GNURadio or custom SDR development
• Familiarity with EMC mitigation, shielding techniques, and enclosure design
• Knowledge of Ofcom, CE marking, FCC regulations, and military standards (MIL-STD, DEF STAN).

What We’re Looking For:

• A degree in Electrical Engineering, RF/Microwave Engineering, Telecommunications, or a related field
• Demonstrated experience in practical RF engineering across the above disciplines.
• Strong analytical, problem-solving, and communication skills.
• Ability to work independently and as part of a multi-disciplinary team.
• Passion for innovation and delivering technical excellence in a defence or high-security context.

Desirable:

• Experience working in defence, aerospace, or similar R&D-intensive industries.
• Understanding of UK/EU/US compliance and export regulations for RF technologies.
