At JockMKT (pronounced “Jock Market”), we are building the second-screen experience for live sports with a social, interactive daily fantasy sports (DFS) marketplace where users buy and sell shares of players in real-time with real money. With all shares based on guaranteed payouts, JockMKT has rapidly grown transaction volume and processes millions of dollars of user trades each month.

Since launching in 2020, JockMKT has expanded gameplay from support for the PGA and NFL to the NBA, MLB, NHL, and NASCAR, and released innovative new products for our customers across our mobile apps, web platform, and open REST and websocket-based API. Headquartered in Boston, we embrace workplace flexibility with a hybrid work model and hire remotely across US time zones.

As a small team, we’re constantly pushing ourselves to solve new problems. We primarily develop with Typescript with our type system at the heart of our code base, utilizing Go and Python in specific trading contexts. We are self-starters who are always interested in learning ‘why’ as we encounter new challenges.
