RF Engineer / RF Technician (m/f/d)

About Us:
STARK is a new kind of defence technology company revolutionizing the way autonomous systems are deployed across multiple domains. We design, develop and manufacture high performance unmanned systems that are software-defined, mass-scalable, and cost effective. This provides our operators with a decisive edge in highly contested environments.

We’re focused on delivering deployable, high-performance systems—not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—today.

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

Qualifications:
• 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
