Job description

Join our Team 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.
