About this role
- Own end-to-end antenna design for Fi products, from proof-of-concept through mass production.
- Lead antenna architecture and contribute to overall system architecture, including RF component selection, schematic capture, and RF PCB layout.
- Design, optimize, tune, and validate antennas to meet aggressive constraints around size, performance, reliability, and manufacturability.
- Work closely with mechanical, industrial design, firmware, leadership, and overseas engineering teams to ensure seamless antenna integration into the product.
- Push antenna performance using a mix of best practices, state-of-the-art approaches, and novel designs where needed — because every dB matters.
- Partner directly with overseas CM/JDM teams on antenna implementation, performance testing, compliance, and production ramp.
- 8+ years of experience designing electrically small antennas for consumer electronics or similar products.
- Bachelor’s or Master’s degree in Electrical Engineering or a related field.
- Proven ability to translate product-level connectivity requirements into RF system and antenna requirements, including managing external consultants and fabrication vendors as needed.
- Deep hands-on experience with custom antenna design in the ~600 MHz to 3 GHz range, including multiband designs, polarization control, antenna isolation in close proximity, and performance optimization near human or animal tissue.
- Strong understanding of antenna integration, including use of enclosures and mechanical structures as part of the antenna system.
- Experience across common antenna fabrication methods and materials, including LDS, FPC, PCB, stamped metal, and ceramic chip antennas, with an understanding of material tradeoffs.
- Comfort building scrappy prototypes using rapid methods such as hand-formed copper, milling, or 3D printing.
- Proficiency with 3D electromagnetic simulation tools for antenna design.
- Strong RF lab skills, including conducted and radiated measurements, antenna tuning, and managing cable effects when testing electrically small antennas.
- Experience operating semi-anechoic chamber testing and supporting regulatory and compliance testing.
- Ability to design simple schematics and PCBs to support antenna prototyping and test.
- Familiarity with firmware and software requirements for RF validation, including sensitivity metrics like BER and PER, and comfort using scripts (e.g., Python) for test automation or analysis.
- Proven track record leading antenna designs from prototype through mass production.
- Willingness to travel to China as needed.
- Time to Recharge: Enjoy flexible PTO to take the breaks you need.
- Top-Notch Health Coverage: We’ve got your back (and teeth and eyes) with full medical, dental, and vision insurance.
- Wellness Perks: Free access to One Medical, Kindbody, and Talkspace to keep you feeling your best.
- Dog-Friendly Office: Bring your pup to work — they’re part of the team, too.
- Give Back to the Pups: Make tails wag with a $500 annual donation to a dog charity of your choice through our BarkBack Program.
- Free Fi Membership: Your furry best friend(s) get all the benefits of a Fi collar, on us!
- Love for Friends + Family: Share the Fi magic with loved ones through our gifting program.
