Full-Stack Senior Software Engineer
About The Position
Amplitude is the leading AI analytics platform, helping over 4,700 customers build better products and digital experiences. The Statsig team at Amplitude is redefining how companies learn, iterate, and ship better experiences. Statsig is one of the fastest-growing and most strategic bets at Amplitude, sitting at the intersection of product, data, and decision-making. This role is not a "take tickets and ship code" role; you will operate as an owner, shaping both the product and the technical direction of a system used by sophisticated product teams. You will work across the stack, NextJS and Node.js, to build intuitive, high-performance experiences that make experimentation accessible, powerful, and trustworthy.
