At Amazon Music, big data fuels the growth of our business. The Metrics and Data Platform organization enables easy, deep, and repeatable analysis of Music customer data. We obsess over making it easy to quickly collect high quality data, manage the behavioral event model, and empower Amazon teams to build responsive and data-driven customer experiences

Our mission is to empower all teams at Amazon Music to make informed decisions and confidently measure their results using high quality, reliable, and timely data.
If you love the challenges that come with client-side application development across mobile, web, and backend, then this role is perfect for you. We collect billions of daily customer signals and own tier-1 services to collect, process, serve, and monitor events in real time. We are embarking on a new journey to build cross-platform analytics SDKs and looking for a candidate to up-level how we design, build, and launch SDKs and consistently instrument applications with behavioral and telemetry data

This role is perfect for a candidate seeking to expand their expertise beyond application development to high-throughput backend engineering.
You are an experienced and passionate full stack Software Development Engineer who wants to solve complex problems at the intersection of client and backend engineering. Working alongside highly motivated engineers on a well-established team, you'll tackle greenfield opportunities with high leadership visibility. The role centers on cross-platform SDK development: building robust, production-grade instrumentation libraries using Kotlin Multiplatform and TypeScript that run across mobile (iOS, Android), web, and backend applications

These SDKs feature intuitive APIs that make it effortless for application teams to instrument their code and collect high-quality behavioral data. As the platform matures, you'll design and build foundational telemetry capabilities serving 100+ Amazon teams, while also contributing to tier-1 backend services that process billions of daily events and self-service tools that empower teams to onboard their applications within minutes and evolve the event model. This is a unique opportunity to bring your mobile and client development expertise to a team that is expanding into cross-platform SDK development, enabling us to better understand our customers.
