Job Description

Welcome to Fi.

We’re a passionate team from Square, Google, Peloton, Uber, and more, working to redefine the dog-human connection. Our mission? Harness cutting-edge technology to transform what it means to be a dog parent.

The pet industry has been stuck in the past for far too long, and we’re here to change that. At Fi, we’re combining expertise and innovation to improve the lives of millions of dogs across the U.S. Real-time location tracking, activity, sleep, and behavior monitoring – and that’s just the start.

The most exciting part? Bridging the communication gap between dogs and humans. Picture a world where you know how your dog feels in real time and how to keep them at their best. That’s the future we’re building at Fi.

If you thrive in a collaborative, forward-thinking environment and are passionate about helping dogs live longer, healthier lives, we want you on the team. Together, let’s redefine the future of dog ownership – turning the “impossible” into “let me find a way.”
