At Underdog, we make sports more fun.
Our thesis is simple: build the best product for sports fans and we will win the space. Founded in 2020, we're one of the fastest-growing sports companies ever, and there’s still so much left to do. We've built and scaled products across fantasy sports, sports betting, and prediction markets, all united in one app that’s seamless, intuitive, and actually fun to use.
Underdog isn’t for everyone. One of our core values is give a sh*t. The people who win here are the ones who care, push, and perform. We’re remote-first by design, but highly collaborative with regular in-person gatherings that help teams build, iterate, and move fast together.
Got that dog in you? Join us.
After all, winning as an Underdog is more fun.
We're looking for a Senior Software Engineer who specializes in React Native to help us build the core betting experience, from the moment a customer builds a slip through submission, confirmation, and settlement. Our work spans full stack in Ruby, iOS, Android, and Web products, and you'll bring deep React Native expertise to that mix, to make sure the experience holds up to a high bar for speed and reliability at scale.
This means owning cross-cutting problems that touch multiple platforms, driving design decisions that hold up under real production traffic, and closing the gap between how a feature is supposed to work and how it actually behaves once it ships. You'll dig into the trickiest bugs and edge cases in the betting experience, help raise the bar for what "done" looks like across the client, and coach other engineers along the way so the patterns you introduce actually stick.
Our target starting base salary range for this position is between $150,000 and $220,000, plus target equity. Final compensation will be determined based on a variety of factors including relevant experience, skills and expertise, interview performance, and other market considerations.
