Fi is looking for an Antenna Engineer to own antenna design end-to-end for our connected pet products. You will work from early system architecture through mass production, collaborating closely with electrical, mechanical, and product teams to solve constraints around size, power, reliability, and manufacturability.
What You'll Do
- 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.
- Push antenna performance using a mix of best practices, state-of-the-art approaches, and novel designs where needed.
- Partner directly with overseas CM/JDM teams on antenna implementation, performance testing, compliance, and production ramp.
What We're Looking For
- 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.
- Deep hands-on experience with custom antenna design in the ~600 MHz to 3 GHz range, including multiband designs, polarization control, antenna isolation, 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.
- 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.
- Proven track record leading antenna designs from prototype through mass production.
- Willingness to travel to China as needed.
Nice to Have
- A passion for dogs is a plus.
Technical Stack
- 3D electromagnetic simulation tools
- Python for test automation or analysis
Team & Environment
