About the Role & Team We’re looking for an Engineering Manager to lead the Delivery and SDK team within Statsig at Amplitude. This team builds the systems that connect developers to Statsig and safely deliver product experiences to end users around the world. The team owns two foundational areas: Delivery: The globally distributed systems that evaluate Experiments and Feature Gates and deliver the resulting experiences to end users. These systems sit directly in the critical path of our customers’ applications, making availability, scale, correctness, and latency essential. SDKs: More than 30 SDKs spanning web, mobile, server, edge, TV, gaming, and emerging platforms. Our goal is to meet developers wherever they build and give them an ergonomic, reliable way to integrate Statsig into any application or technology stack.
