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
