Job summary

Sleeper is hiring Senior and Staff Backend Engineers for Sleeper Picks, our real-money product. Picks is two games sharing one wallet and one user: daily fantasy sports, and prediction markets.

Real money changes the engineering. Prices move in real time, entries surge before games start, and settlements must be correct the moment a game ends. You’ll own systems end to end, from data models to API contracts, partnering with designers and mobile/web teams to ship features.

Qualifications

  • 5+ years backend engineering experience.
  • Shipped features end to end, not only infrastructure.
  • Experience with real-money gaming, payments, or marketplaces a plus.
  • Distributed systems expertise and real-time updates.
  • Deep ownership of architecture at scale.
  • You’re a sports fan with opinions on DFS or prediction markets.

Responsibilities

  • Build and own core Picks systems end to end — contest and entry lifecycle, pricing and market data, settlement and grading.
  • Make real money correct: reconciliation and settlement logic that’s right the first time.
  • Handle real-time at scale: moving prices and positions, surges, and settlements.
  • Partner with risk and trading on exposure management and internal tooling needs.
  • Integrate with third-party projection, market, and payments providers, and design for failures.
  • Ship features end to end with designers and mobile/web engineers.
  • Staff: own architecture, raise the bar through design and code reviews.
