Netflix Games Systems L5 — foundational backend platform for cloud games and developer tooling
An L5 backend engineering interview for Netflix's Games Systems team, the group building identity/auth, control-plane, cloud saves, leaderboards, achievements, and the APIs/SDKs that internal and external game developers build on top of. Expect deep questions on distributed systems design, high-throughput low-latency infrastructure, and technical leadership at scale, since the role explicitly asks for 10+ years operating large distributed systems.
