RF Design Engineer

Job Title

RF Design Engineer

Role Summary

Design and deliver PLL and RF analog IP for wireless silicon in a cross-functional silicon design team based in Munich. The role focuses on circuit-level solutions, integration with system and digital teams, and collaboration with technology and foundry partners to enable power-efficient, high-performance wireless chips.

This is a hands-on engineering role with opportunity to influence architecture, verification, and silicon bring-up across multiple product generations.

Experience Level

Mid-level. Specific years of experience are not stated; role requires proven RF circuit design experience.

Responsibilities

Primary duties include circuit design, integration, verification, and silicon characterization for RF PLL and related analog blocks.

• Design PLLs, oscillators, frequency dividers, phase detectors, biasing blocks, and local oscillator chains for wireless ICs.
• Translate system and product requirements into IC block specifications working with system architects and platform teams.
• Collaborate with digital design, layout, system engineering, and integration teams to deliver IP and verify top-level functionality and performance.
• Work with process and technology teams and foundries on process evaluation and device selection.
• Support silicon bring-up: characterize, debug, and optimize RF performance at chip and system level together with RF test engineers.
• Perform EM modeling and simulation to validate designs and interactions on chip and package.

Requirements

Minimal and preferred technical qualifications for candidates.

• Must-have
  • Profound experience in RF circuit design techniques.
  • Experience using Cadence design tools.
  • EM modelling and simulation skills.
  • Proficiency in English.
• Nice-to-have
  • Experience with wireless PLL architectures in CMOS and translating system KPIs to circuit requirements.
  • Deep knowledge of low-noise, broadband, power-efficient PLLs and frequency-conversion blocks.
  • Experience optimizing RF performance via trimming, calibration, and crosstalk mitigation.
  • Understanding of RF device modeling, packaging effects, integrated inductors/coils, supply isolation, and HF ESD structures.
  • Hands-on experience in high-frequency silicon characterization and on-system debugging.

Education Requirements

MSEE or PhD is required, or equivalent practical experience.
