At WHOOP, we're on a mission to unlock human performance. WHOOP empowers members to perform at a higher level through a deeper understanding of their bodies and daily lives.

As an RF Engineer II at WHOOP, you will be a member of the Electrical Engineering team and work cross functionally developing and supporting cutting edge wearable technologies. You will be the primary technical resource for RF subject matters on the team, including wireless communications, wireless power transfer, coil and antenna design, system integration, performance validation, and regulatory certification. You will regularly interface with internal engineering teams, external vendors and suppliers, testing and certification bodies, and contract manufacturers (CMs) to deliver exceptional product performance, safety, and reliability. You are deeply familiar and comfortable with RF concepts and best practices and you have the vocabulary and communication skills to work with a diverse cross functional team.


    • Support the architecture, development, integration, and validation of wireless power transmission, wireless communication, and other RF subsystems while growing into a technical leadership role
    • Hands-on analysis, validation, and debugging using lab equipment including spectrum analyzers, impedance analyzers, oscilloscopes, etc…
    • Circuit simulation and mathematical analysis using SPICE, HFSS, Matlab, or similar tools
    • Work in a highly cross-functional environment with firmware, mechanical, and manufacturing teams to deliver fully validated RF systems
    • Define RF hardware test requirements and design test systems for in-house performance evaluation as well as production manufacturing test
    • Leverage contractors to support new and existing system designs as necessary
    • Management and technical support of wireless certification testing to standards such as FCC Title 47 Part 15 and Part 18, CISPR 11, EN 55035, EN 50366, RED Directive, etc…
    • Schematic capture and PCB layout of electrical circuits using tools such as Altium
    • Electrical, electromechanical, and RF component selection
    • Work with diverse cross-functional teams to validate hardware features, improve device performance, and provide support
    • Support research and development of next generation features, technologies, and manufacturing techniques that enable miniaturization and feature expansion
    • Travel up to 15%, domestically and internationally (North America, Asia, Europe)


    • BS or greater in Electrical Engineering or related field
    • 3+ years experience in relevant fields
    • Experience with RF communication systems, including antenna design, integration, and desense for Bluetooth, WiFi, GNSS, and 5G applications
    • Extensive RF and electrical engineering skills including circuit design, component fundamentals, power supply design, layout, digital communication protocols, manufacturing techniques, and debug
    • Exposure to wireless power transmission design considerations, especially for small form factors. This includes coil design, system characterization, matching and tuning, design for manufacture, and knowledge standards such as QI or NFC WLC.
    • Lab experience including soldering and the use of multimeters, oscilloscopes, spectrum analyzers, VNAs, etc.
    • Experience with simulation software such as SPICE and HFSS
    • Familiarity with ECAD tools such as Altium and PLM tools like Arena
    • Exposure to wireless power transfer standard such as NFC Wireless Charging or Qi
    • Experience in high volume manufacturing in consumer or medical spaces
This role is based in the WHOOP office located in Boston, MA. The successful candidate must be prepared to relocate if necessary to work out of the Boston, MA office.
