Senior Full Stack Product Engineer

Kickoff is on a mission to increase access to preventative health. We are the first to offer personal training covered by health insurance, democratizing access to life-changing coaching while reducing medical costs for our health insurance partners. We combine the best of AI with the best of highly credentialed human coaches to create something greater than the sum of the two parts.

We’re looking for a Product Engineer to help us build the future of personalized wellness. We’re looking for incredible full stack engineering skills, but we also want to see that you operate at the bleeding edge of technology.

The recent advances in AI tools enable a single individual to make a much bigger impact than ever before. Consequently, we’re looking for someone with experience leveraging the latest cutting-edge AI tools to build delightful software, tackling product and design as well as engineering challenges.

Sometimes we’ll look for you to solve ambiguous, tricky customer problems soup to nuts with the latest tools. Other times, you’ll tackle more traditional engineering challenges, leveraging AI developer tools and usually incorporating AI-powered features. It will never be dull, nor easy.
