At FanDuel, we don’t just write code — we engineer the pulse of sport. Every NFL touchdown, NBA buzzer-beater, and MLB walk-off home run is backed by the platforms our teams build, scale, and evolve in real time. Millions of fans engage with our products every single day — and you’ll help make that experience faster, smarter, and more thrilling.
We’re part of the FanDuel Group, the premier mobile gaming company in North America and a proud member of Flutter Entertainment — the world’s largest sports betting and gaming operator. From Melbourne to New York, Edinburgh to Dublin, our engineers collaborate across continents to craft experiences that connect sports fans everywhere.
Now, we’re looking for a Lead Engineer (.NET) to join our Sportsbook engineering group — a team of curious, pragmatic builders shaping the future of sports technology.
