Welcome to Fi.

We’re a passionate team from Square, Google, Peloton, Uber, and more working to transform the dog-human relationship. Our mission? Develop cutting-edge technology to revolutionize what it means to be a dog parent. The dog 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 the millions of dogs 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 dogs and humans. Imagine a world where everyone knows how their dog 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 dogs 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 dog ownership together.

Fi is looking for a Senior Fullstack Engineer! 

As a pivotal member of our engineering team, you will report directly to the Backend Lead and play a crucial role in shaping our technical direction. You thrive on the challenge of transforming concepts into remarkable solutions and are well-versed in a variety of backend technologies, along with an understanding of best architectural practices.

What You'll Do:

  • Collaborate with the engineering team to deliver exceptional services and backend systems.
  • Engage in complex engineering challenges on the backend, covering creating dashboards, data aggregation, machine learning, and the development of scalable services.
  • Contribute to the development and deployment of our technology ecosystem, gaining proficiency in new technologies as you go.
  • Work with our native mobile applications and backend stack, aligning with industry standards.

What You Bring:

  • Minimum of 6 years of experience as a Software Engineer, specializing in technologies such as AWS, TypeScript, NodeJS, and React.
  • Proven track record of delivering outstanding software, from initial design to production deployment.
  • Experience in developing consumer products from inception to completion is highly desirable.
  • Passionate about technology and eager to drive innovation.
