Senior Software Development Engineer

Sr. Software Dev Engineer - Emerging Stores, LSXE E3

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.

Key job responsibilities

Design, build, and own distributed systems and services that power customer experience, seller experience, and fulfillment capabilities across EU Emerging Markets stores
Lead technical design and architecture for high-impact, time-sensitive initiatives — including same-day delivery CX features (FST, storefront, basket-building), AI/ML-powered local selection identification, and automated seller expansion platforms
Work across ambiguous, greenfield problem spaces where requirements evolve and the right solution requires both technical depth and business judgment
Partner with EU5 host teams, product managers, and business stakeholders to secure prioritization for EM-specific needs and deliver incremental launches without sacrificing architectural integrity
Drive data-driven decision-making — instrument systems for metric monitoring, build automation for auditing, and own the business outcomes your systems enable
Mentor engineers, conduct rigorous code reviews, and raise the technical bar of the team
Contribute to the E3 GenAI productivity strategy — leveraging Amazon Config Service (ACS), Freebird, and Amazon GenAI tools to drive meaningful efficiency gains in feature delivery

A day in the life
You might start the morning reviewing the technical design for a new local brand identification model — an AI/ML solution that needs to reliably surface locally relevant selection across five EU markets at scale. By afternoon, you're in a design review for the Same-Day CX feature set launching across NL/BE/SE/IE, working through the FST and storefront defaulting logic with engineers in Luxembourg. Later, you're unblocking a junior engineer on the PanEU FBA Demand implementation, and closing the day by reviewing metrics from the Belgium MFC launch pipeline. Every decision you make has a direct line to customer experience and the P&L.

About the team
Amazon's EU Emerging Markets stores — Belgium, Netherlands, Poland, Sweden, and Ireland — represent 26% of Europe's population and 24% of EU5 GDP, yet remain one of Amazon's largest untapped growth opportunities on the continent. That gap is the opportunity.

The E3 Tech organization was established to close it. We are a newly unified engineering team spanning Emerging Markets, Exports, and Expansion, operating under a single technical charter to build the systems that will make Amazon the preferred shopping destination across Europe's fastest-growing markets. We work on greenfield problems with real P&L stakes — every system we build directly impacts customer experience, seller success, and Amazon's path to profitability in these stores.

We are building our Bangalore engineering team as a core part of this mission. You will work alongside engineers in Luxembourg and Hyderabad, partnering closely with EU business, product, and partner teams to deliver at Amazon scale.
