Jobbeschreibung

Join our engineering team to develop advanced RF subsystems for next-generation datalink platforms. You will focus on RF circuit design and system integration, working closely with antenna, DSP, mechanical, and software teams to deliver high-performance communication hardware.

This role combines circuit design, system-level analysis, hands-on lab validation, and automated test development in a fast-paced engineering environment.

What you'll do

• Design and simulate RF front-end circuits across RF and microwave frequency bands.
• Develop power amplifier stages, low-noise amplifiers, mixers, filters, and frequency generation circuits.
• Perform RF cascade analysis, including gain, noise figure, linearity, stability, and dynamic range.
• Conduct link budget analysis and support system-level RF performance optimisation.
• Create circuit-level and system-level simulations using industry-standard RF design tools.
• Design schematics and support PCB layout for high-frequency circuits.
• Collaborate with cross-disciplinary teams to integrate RF subsystems into complete datalink systems.
• Develop validation and production test methodologies for RF hardware.
• Perform lab characterisation using network analysers, spectrum analysers, signal generators, and related instrumentation.

What we're looking for

• Bachelor's degree in electrical engineering, physics, or a related discipline.
• 3+ years of industry or research experience in RF/microwave circuit design.
• Experience designing RF signal chain components such as PAs, LNAs, mixers, filters, or PLLs.
• Strong understanding of impedance matching, S-parameters, noise figure, linearity, stability, and RF system fundamentals.
• Experience with RF test equipment (VNA, spectrum analyser, signal generator, power meters).
• Experience with RF simulation tools such as ADS, AWR, or similar.

Bonus: not required

• Experience designing high-linearity or high-efficiency power amplifiers.
• Experience with RF system-level modelling and link analysis.
• Familiarity with digital modulation schemes (QPSK, QAM, APSK) and their RF implications.
• Experience with PCB schematic and layout tools (Altium or equivalent).
• Experience working in datalink or high-reliability communication systems.

How the hiring process works

• Intro call. 30 minutes with our recruiting team. We'll learn about your background, and you'll learn about the mission.
• Deep dive. A working session with one of our RF engineers on a real circuit or link-budget problem.
• Case study, in Munich. A visit to the lab to walk through an RF design scenario with the team, in person if you can make it or over Teams if you can't.
• The offer. By now you've likely already met our CEO. This round is where we make it official: fast, transparent, and built around the mission.
