Empowering the world starts with living our values and empowering our team. As a quickly growing company focused on helping people live healthier and happier lives, we ensure that our team members have what they need to do their best work — both in and out of the office. We are looking for a Staff Antenna Design Engineer to develope high performing miniaturized antennas and RF to our future products. What You Will Do: You will create high performing wearable products. Design, simulate, and optimize antennas for low-power wearable devices, including multi-band multisystem solutions. Perform electromagnetic simulations (e.g., CST, HFSS, others) and validate designs with bench and OTA measurements. Build prototypes quickly and effectively to evaluate design concepts Collaborate cross-functionally with mechanical, electrical, and firmware teams to integrate antennas into highly constrained form factors. Conduct over-the-air (OTA) performance testing and troubleshooting in collaboration with other engineering teams. Drive root cause analysis and design iteration for antenna performance issues in prototypes and production units. Work with suppliers, manufacturing partners, and Oura manufacturing teams to ensure antenna performance is maintained throughout production. Document design processes, results, and performance metrics for internal knowledge sharing and regulatory compliance. Stay up to date on emerging materials, methods, and technologies in miniature antenna design. Travel to support prototype builds in both Europe and Asia: ~5-20% of time yearly We Would Love to Consider You for this Role if You Have: 10+ years experience in antenna and RF design, preferably for compact consumer electronics, wearables or IoT devices Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related field. Proficiency with electromagnetic simulation tools such as CST Microwave Studio, Ansys HFSS or others Experience with antenna measurement tools (e.g., vector network analyzers, spectrum analyzers, radio communication testers, OTA chambers). Strong understanding of RF fundamentals, antenna concepts, matching networks, and PCB layout considerations for antennas. Proven ability to collaborate across disciplines and communicate technical concepts clearly. Knowledge of Industry Standards and Regulatory Requirements: Be familiar with industry standards and regulations related to wireless communication, such as those from the FCC, ETSI, or ITU. Nice to have: Experience designing antennas for wearable or ultra-compact devices. Familiarity with Bluetooth, BLE, NFC, W
