RF Engineer (All levels)

Role Overview
We are building the next generation of autonomous UAV systems and are looking for an Electromagnetic Engineer to lead EM design, integration, and compliance across our drone platforms. You will work at the intersection of RF, power electronics, antenna systems, and EMC to ensure mission-critical performance in demanding environments.
Key Responsibilities
Design and optimise RF/microwave subsystems for command & control (C2) links, telemetry, and payload communications
Lead EMC/EMI analysis, testing, and mitigation across the full UAV stack (airframe, avionics, payload)
Develop antenna systems including patch, monopole, conformal, and phased array designs for multi-band operation
Perform link budget analysis and RF coverage modelling for BVLOS (Beyond Visual Line of Sight) operations
Conduct signal integrity analysis on high-speed PCBs and flex circuits
Collaborate with mechanical, power, and firmware teams to ensure EM compatibility at system level
Support regulatory compliance: FCC, CE, DO-160, MIL-STD-461, STANAG
Define EM test plans, manage test campaigns in an EMC chamber or open-area test site (OATS)
Investigate and resolve interference issues between onboard systems (GPS, video downlink, LiDAR, ESCs)
Create and maintain EM design documentation, test reports, and compliance records
Requirements
Must-Have
Bachelor's or master’s degree in electrical engineering, RF Engineering, or related field
Hands-on EMC / RF engineering experience
Proficiency in EM simulation tools (CST, HFSS, ADS, or equivalent)
Experience with spectrum analysers, VNAs, and EMC test equipment
Solid grounding in Maxwell's equations, transmission line theory, and antenna fundamentals
Familiarity with UAV or aerospace platform constraints
Nice-to-Have
Experience with software-defined radio (SDR) platforms
Knowledge of FHSS / DSSS modulation for resilient datalinks
Familiarity with drone regulations: CAA, EASA, FAA Part 107
Anti-jamming, GPS spoofing mitigation, or secure comms background
Exposure to MIL-STD-461 or DEF STAN 59-411 environments
Experience with SWAP-C (size, weight, power, cost) trade-offs
