Your Mission

As an RF Engineer you will Design, integrate, and validate robust RF systems for military UAV platforms, delivering secure communications and electronic warfare capability in contested environments.

Responsibilities

• Select, design, and integrate RF hardware including SDRs, antennas, filters, LNAs, power amplifiers, and front-end modules
• Define system-level requirements and ensure RF systems meet performance, environmental, and regulatory standards
• Develop robust communication architectures for UAV command, control, telemetry, and payload data transfer
• Support the design and integration of electronic warfare functions such as signal detection, jamming, spoofing, and RF hardening
• Perform RF simulations, link budget calculations, and range performance modeling
• Work with mechanical and systems engineers on antenna placement, EMC/EMI mitigation, and SWaP optimization
• Evaluate and qualify COTS and custom RF components for use in military platforms
• Plan and execute lab testing, range validation, and flight trials of RF systems
• Ensure compliance with NATO STANAGs, MIL standards (e.g. MIL-STD-461, 464, 810), and relevant frequency allocation regulations
• Contribute to safety, reliability, and certification documentation, including SC-Light UAS or equivalent pathways where applicable

Required Skills

• Degree in Electrical Engineering, RF Engineering, Telecommunications, or a related discipline
• Experience in RF systems design, ideally in aerospace, defense, or tactical communications
• Solid experience with software-defined radios, RF front-end design, and antenna system integration
• Knowledge of RF propagation, modulation schemes, spectral efficiency, and interference mitigation
• Familiar with RF test equipment (VNAs, spectrum analyzers, signal generators) and RF design/simulation tools (e.g. HFSS, CST, MATLAB)
• Understanding of EMC/EMI principles and ruggedization of RF systems for harsh environments
• Familiarity with relevant military standards and NATO STANAGs for communication and EW systems
• Awareness of civil UAV certification requirements (e.g. SC-Light UAS) is a plus
• Strong analytical, documentation, and communication skills
• Ability to travel to various testing sites in Europe when needed
• Eligible for security clearance (or already holds one)
• Fluent in English; German is beneficial, additional languages are a plus Nice-To-Have If you're interested in building the future of European Defence with us, and you see yourself reflected on the description above, please send us your CV in English . We're looking forward to meeting you!
