## Job description

Welcome to Fi.

We’re a passionate team from Square, Google, Oura, Peloton, Uber, and more working to transform the human-pet relationship. Our mission? Develop cutting-edge technology to revolutionize what it means to be a pet parent. The pet industry remains firmly stuck in the past and we are here to change that. Fi is leveraging our team's talent and expertise to improve the lives of millions of pets in the U.S. Real-time location tracking, activity, sleep and behavior monitoring – and that's just the beginning.

The most exciting aspect of our work? Bridging the communication gap between pets and humans. Imagine a world where everyone knows how their pet feels in real time and how to keep their best friend in good shape. That's the future we're building at Fi.

If you're someone who thrives in innovative, collaborative work environments and feels strongly about helping pets live longer, better lives, Fi could be the perfect fit. Join us in our pursuit of the “impossible,” or as we call it here “let me find a way,” to redefine the future of pet ownership together.

Fi is looking for an Antenna Engineer!

Fi is looking for an Antenna Engineer to own antenna design end-to-end for our connected products, shaping how they perform in the real world, not just on paper. You’ll work from early system architecture through mass production, partnering closely with electrical, mechanical, and product teams to solve hard constraints around size, power, reliability, and manufacturability. The work spans RF design, antenna integration, tuning, and validation, and directly sets the technical foundation for Fi’s next generation of high-volume consumer hardware operating at scale.

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 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.

What You'll Bring:

- 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.

Why You'll Love Us:

- 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.

The anticipated base salary range for this position is $150,000–$250,000. Actual compensation will vary based on multiple factors, including skills, experience, market conditions, and role scope, which may evolve during the hiring process. As a fast-growing Series B startup, Fi evaluates compensation opportunistically to align with the right candidate. This role is also eligible for equity compensation.
