  • You'll own significant parts of the backend stack and help raise the bar for performance, scalability, and reliability at Sleeper
  • Design and build core backend systems that power Sleeper's games and real-time user experiences-fantasy contests, Sleeper Picks, user profiles, leaderboards, and more
  • Build scalable, distributed systems capable of handling millions of concurrent users with low latency and high availability
  • Own backend initiatives from concept to deployment, ensuring clean interfaces, well-documented services, and resilient infrastructure
  • Optimize system performance and proactively address bottlenecks through monitoring, profiling, and capacity planning

  • Bonus: Passion for sports, gaming, or building multiplayer or real-time systems
  • Bonus: Proficiency in Elixir
  • Excellent communication and collaboration skills
  • Strong product mindset-you care about the why, not just the how, and you build with users in mind
  • 3+ years of backend software engineering experience
  • Solid knowledge of databases (both SQL and NoSQL), caching strategies, and message queues (e.g., Kafka, RabbitMQ, Pub/Sub)
