RF / Microwave Engineer

A Munich-based deep tech company is developing next-generation datalink platforms for high-performance communications. The engineering team works at the intersection of RF hardware, DSP, antenna design, and software - building systems where performance and reliability are non-negotiable.

The role

As an RF/Microwave Engineer, you'll design, simulate, prototype, and validate RF front-end circuits for high-performance datalink systems operating in sub-6 GHz and microwave frequency bands. You'll develop signal chain architectures including power amplifiers, low-noise amplifiers, mixers, filters, and frequency synthesis stages.

This role combines circuit design, system-level analysis, hands-on lab validation, and automated test development in a fast-paced engineering environment. You'll work closely with antenna, DSP, mechanical, and software teams to deliver complete communication hardware.

All levels welcome - from mid-level to senior.

What youll 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: 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 you bring

Bachelor's degree in electrical engineering, physics, or a related discipline

3+ years of industry or research experience in RF/microwave circuit design

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:

Experience designing high-linearity or high-efficiency power amplifiers

RF system-level modelling and link analysis experience

Familiarity with digital modulation schemes (QPSK, QAM, APSK) and their RF implications

PCB schematic and layout tools (Altium or equivalent)

Background in datalink or high-reliability communication systems
