Working within a global network of experts, you will have the opportunity to make a tangible impact on both customer success and future technology development.

Your tasks Include:

• Provide technical expertise on RF-related behavior of adhesive, conductive, and functional material systems in customer applications.
• Support the development and optimization of RF- and antenna-compatible solutions, including conductive layers, shielding concepts, and interference mitigation strategies.
• Analyze electromagnetic interactions, signal integrity challenges, and material-related performance impacts in demanding application environments.
• Serve as the technical interface for strategic global customers, providing expert consultation and application-oriented recommendations.
• Support troubleshooting, root-cause analysis, and problem-solving activities throughout the customer development process.
• Collaborate closely with R&D, Product Development, Application Engineering, and Global Key Account Management teams across Europe, Asia, and North America.
• Facilitate the transfer of technical insights from laboratory research into scalable customer solutions.
• Build and share internal expertise in RF-related technologies, contributing to knowledge transfer and capability development across the organization.
• Represent tesa's technical competence in customer meetings, workshops, and cross-functional project discussions.

• Master's degree or PhD in Electrical Engineering, Physics, Communications Engineering, Materials Science, or a related technical field.
• Solid knowledge of RF engineering, electromagnetics, antenna systems, signal propagation, EMC, shielding, or related disciplines.
• Experience working with RF-related applications such as wireless communication systems, antennas, EMC testing, electronic devices, or material interactions.
• Ability to connect scientific principles with practical engineering and customer application challenges.
• Strong analytical, troubleshooting, and problem-solving capabilities.
• Excellent communication skills and the ability to explain complex technical concepts to both technical and non-technical audiences.
• Collaborative mindset with the ability to work effectively across international and cross-functional teams.
• Customer-oriented approach and confidence operating in dynamic, high-expectation project environments.
• Fluency in English; German language skills are considered an advantage.
• Openness and willingness to relocate to Palo Alto, California, after the onboarding phase in Hamburg.
