Principal Radio Frequency Engineer
Group Overview
Electromagnetic and Cyber Group (EM&C) is responsible for developing flexible and survivable advanced electronic warfare and secure communications equipment while providing the industry’s leading signals intelligence, electronic warfare, and cyber experts. Metrea specialises in signal classification, direction finding, advanced geolocation techniques, and waveform development including waveforms for MANET and LPI/LPD applications. Metrea also develops special purpose radios for government customers and licenses DF and geolocation solutions to multiple OEMs.
The Expeditionary Operations Lab, or EXOLAB, focuses on the rapid development, integration, evaluation and delivery of expeditionary capabilities within the Electromagnetic Warfare and Cyber domain. EXOLAB works across research and development, experimentation, prototyping, systems integration, trials and operational delivery. The team addresses complex customer problems by combining existing technologies, emerging capabilities and internally developed solutions into deployable systems. The lab operates across airborne, land, maritime and dismounted environments, with a strong emphasis on practical engineering, rapid learning and delivering systems that are operationally relevant, supportable and resilient.
Position Summary
We are seeking a Principal RF Engineer to lead and support the research, design, development, integration and delivery of radio-frequency systems for expeditionary Electronic Warfare, signals intelligence, spectrum operations and secure communications capabilities.
The role will be responsible for the RF engineering aspects of prototype and operational systems, including RF architecture, receiver and transmitter chains, antenna systems, signal distribution, filtering, amplification, frequency conversion, interference management and system performance analysis.
The Principal RF Engineer will operate as a senior technical authority within a multidisciplinary team comprising electrical, systems, mechanical, software, cyber and operational specialists. The role will support the full engineering lifecycle, from concept development and technology evaluation through detailed design, integration, verification, trials, deployment and through-life support.
This is a practical, delivery-focused engineering role. The successful candidate will be comfortable moving between theoretical analysis, simulation, laboratory testing, prototype development, platform integration and field trials.
The role will be based either in Lincoln or London, with a longer-term intent to transition the primary location to London if hired initially in Lincoln.
What You'll Do
Design, develop and integrate RF systems for expeditionary Unmanned Systems control, Electronic Warfare, signals intelligence, spectrum-monitoring and secure communications capabilities.
Develop RF system architectures covering antennas, receivers, transmitters, amplifiers, filters, frequency conversion, switching and signal distribution.
Conduct RF performance analysis, including gain, noise figure, sensitivity, dynamic range, linearity, link budgets and interference assessments.
Support rapid R&D, prototyping and technology evaluation, translating operational requirements into practical and deployable RF solutions.
Integrate commercial, government and internally developed RF equipment across airborne, vehicle-mounted, maritime, fixed-site and unmanned platforms.
Plan and conduct RF testing, characterisation, fault diagnosis, verification and corrective engineering activity.
Ensure RF designs consider electromagnetic compatibility, spectrum management, grounding, bonding, shielding, environmental protection and relevant standards.
Work closely with electrical, mechanical, software, cyber, systems and operational teammates throughout the engineering lifecycle.
Support UK and international trials, demonstrations, installations, commissioning and operational deployments.
Provide RF technical leadership, design assurance and clear engineering recommendations to customers, suppliers and internal stakeholders.
What You Bring
Degree in RF Engineering, Electronic Engineering, Electrical Engineering, Telecommunications Engineering or a closely related discipline, or equivalent relevant experience
Minimum of seven years’ experience in RF systems design, development, integration, testing or delivery
Experience working with complex RF systems within defence, aerospace, telecommunications, Electronic Warfare, signals intelligence, secure communications or a related sector
Experience with Software Defined Radios, digital RF architectures and the collection or analysis of IQ data
Experience designing, integrating or supporting RF systems for unmanned systems, including uncrewed aerial, ground or maritime platforms
Strong understanding of RF receiver and transmitter architectures, including amplifiers, filters, mixers, oscillators, switches and frequency-conversion stages
Experience conducting cascade analysis, link-budget calculations and assessments of gain, noise figure, sensitivity, linearity and dynamic range
Practical experience with antenna systems, RF distribution, transmission lines, impedance matching, grounding, bonding and shielding
Strong RF test, measurement and fault-finding skills using equipment such as spectrum analysers, vector network analysers, signal generators, oscilloscopes and power meters
Experience using RF simulation, modelling, schematic-capture or system-analysis tools
Ability to work effectively within multidisciplinary teams spanning electrical, mechanical, software, cyber, systems and operational disciplines
Ability to produce clear technical documentation, communicate engineering recommendations and travel regularly within the UK and internationally
Additional Eligibility Qualifications
Experience designing expeditionary, deployable, ruggedised or rapidly reconfigurable RF capabilities
Experience integrating RF systems onto airborne, vehicle-mounted, maritime, fixed-site or dismounted platforms
Understanding of antenna selection, placement, radiation patterns, platform effects and co-site interference
Experience with wideband receivers, transmit chains, power amplifiers, low-noise amplifiers, filters and RF switching networks
Experience conducting electromagnetic compatibility, electromagnetic environmental effects and radio-frequency interference assessments
Familiarity with relevant defence, aviation, maritime, spectrum-management or RF engineering standards
Experience supporting prototype builds, field trials, exercises, customer demonstrations or operational deployments
Knowledge of systems engineering, size, weight, power and cooling analysis, low-volume manufacturing, component obsolescence and through-life support
