Machine Learning Engineer

About the job:


Fi is rethinking the relationship between dogs and humans. We build products for your dog to live a longer, better life. We are full of experienced, passionate people that have built and shipped outstanding products for Nest, Square, Google and Uber who all care about their dogs. Together, we're bringing a digital revolution to the dog space.

Today's dog industry is a relic from the 80s. We are using technology to improve dogs' lives and make the 100 million dogs in the US live longer. Dogs' life expectancy hasn't improved in decades - we are here to change this. We are keeping dogs safe by allowing owners to keep track of their whereabouts. We are keeping dogs healthy by showing owners how much they should exercise and keep them accountable. We also monitor health patterns like sleep and overall balance of activity versus resting patterns.

The hardest part about being a dog owner is they can't tell you when something is wrong. Fi aims to change that; We're looking for people to join us who love a good challenge—and of course, dogs. We set the bar high at Fi. In our world, "impossible" means "let me find a way".
