The role

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.

What you'll do

  • 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
