Join our cutting-edge antenna development team and play a key role in shaping the future of mobile communication. We're looking for a passionate RF Developer to drive innovation in radiator and antenna front-end design within our product development organization.
As an RF Developer, you will focus on developing radiating elements and passive radiation pattern-shaping structures for our mobile communication base station antennas. You'll be involved in the entire development cycle-from concept to integration-working with state-of-the-art simulation tools and collaborating in cross-functional, international teams where innovation and continuous improvement are part of everyday life.
What You'll Do
- Design, simulate, and verify radiating components for passive multiband base station antennas and active antenna systems
- Drive the 3D simulation and development of radiating components from initial concept to mass production
- Integrate and optimize radiating elements within the overall antenna system
- Conduct and support RF measurements on hardware prototypes
- Document and present results clearly within project and department teams
- Collaborate with stakeholders to support troubleshooting and technical guidance
- Continuously improve component design, performance, and cost-efficiency
- Work closely within cross-functional, global teams to share knowledge and innovate together
What you bring
- Bachelor's with relevant experience, or a Master's/University degree in Electrical Engineering or related field with a strong RF background
- Proven experience in RF and antenna design
- Solid understanding of radiating component development and integration
- Expertise in 3D EM simulation tools (e.g., CST Microwave Studio, Ansys HFSS)
- Experience with 2D simulation tools (e.g., AWR Microwave Office, Keysight ADS)
- Basic knowledge of RF and antenna measurement techniques
- Strong analytical and problem-solving skills
- Highly motivated, with a structured and self-driven work style
- Excellent teamwork and communication skills in an international environment
- Proficiency in English, both written and spoken
Nice to Have
- Experience with RF filter design or frequency selective surfaces (FSS)
- Familiarity with machine learning and optimization algorithms
- Knowledge of MATLAB, Python
- Understanding of PIM/EMC design and measurements
- German language skills are a plus
The role requires relocation to Rosenheim, Germany.
