U Emerging Markets — Belgium, Netherlands, Poland, Sweden, and Ireland — represent over a quarter of Europe's population and nearly a quarter of EU5 GDP, yet remain one of Amazon's largest untapped growth opportunities on the continent. The E3 (Emerging, Exports & Expansions) Tech organization exists to close that gap. As a Sr. SDE on the E3 Emerging Markets team, you will design and own the distributed systems and services that directly shape how customers discover products, how sellers expand across borders, and how Amazon competes with entrenched local players across five high-growth European markets. This is a greenfield-heavy, high-ownership role — you will architect next-generation capabilities in local selection, same-day delivery CX, and automated seller expansion, working from our Bangalore engineering hub alongside teams in Luxembourg and Hyderabad. Every system you build has a direct line to customer experience and the P&L.
