KO2 is recruiting on behalf of a fast-growing engineering scale-up working on defence and space projects.
As a RF Engineer, you'll help design, test and improve the low-power radio links and mesh networks behind those systems. It's a hands-on role in a small, close team: bench work, field trials and customer demonstrations, with real users and real deadlines.
Key responsibilities
- Design, develop and optimise low-power RF hardware and radio links for small, battery-powered sensor nodes
- Develop and improve mesh networking, including routing, multi-hop performance, latency and resilience
- Carry out link budget analysis and range planning, and help choose antennas, bands and radio modules
- Support RF front-end and antenna design, PCB layout reviews, and matching and tuning on the bench
- Test and characterise radio performance in the lab and field using spectrum analysers, VNAs and signal generators
- Work with embedded, hardware and AI teams to balance range, data rate and power within tight size, weight and power limits
- Support field trials and customer demonstrations, including deploying units and diagnosing link issues on site
- Write clear test reports and technical documentation, and support EMC and regulatory compliance
Essential skills and experience
- Degree in electronic engineering, physics or a related subject, or equivalent experience
- Solid commercial experience in RF or wireless engineering at mid level
- Strong understanding of low-power radio design and protocols such as BLE, IEEE 802.15.4, Thread, Zigbee, LoRa or proprietary sub-GHz systems
- Practical mesh networking experience, including topology, routing and multi-hop behaviour
- Confident with RF test equipment and bench debugging
- Good knowledge of antenna fundamentals, impedance matching and link budgets
- Ability to achieve SC clearance, if you already hold it even better.
- Willing to travel occasionally for field trials and demonstrations
- Experience with low-power wireless SoCs
- Embedded firmware in C or C++ for radio stacks
- RF simulation and PCB design tools
- Defence, security or space project experience
- Designing for harsh or remote outdoor environments
