About the Team
The Sportsbook Platform team owns the backend that powers theScore Bet Sportsbook. We are the team behind the marketplace: the event, market, and page-composition systems that decide how bets are surfaced, organized, and updated for the user. What we own is everything around markets: how markets are modelled, how pages are composed, and how quickly changes propagate to patrons.
Our stack is primarily Elixir and Phoenix, backed by PostgreSQL, Kafka, and a service mesh of gRPC and GraphQL endpoints running on Kubernetes. We operate at the scale and latency that live sports demand, which means we care deeply about production hygiene: load testing, tracing, structured monitoring, and clear on-call expectations. You will also spend meaningful time reviewing other teams' work in our codebase, defining the shape of upcoming work, and mentoring the engineers around you. We care about the craft as much as the ship. If you like distributed systems, functional programming, live production traffic, and a team that treats software quality as a first-class product concern, you will feel at home here.
