📋 Description

• 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. • Architect scalable, distributed systems capable of handling millions of concurrent users with low latency and high availability. • Lead 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. • Collaborate cross-functionally with product, design, and frontend teams to deliver features that users love. • Mentor engineers, provide thoughtful code reviews, and shape backend engineering best practices and standards. • Drive innovation, technical direction, and team culture as a key engineering voice at the leadership level.
