READY TO UNLOCK FBA'S NEXT CHAPTER?

Fulfillment by Amazon (FBA) is the service that lets sellers worldwide leverage Amazon's world-class logistics infrastructure — storage, fulfillment, delivery, returns — as a service. Sellers from Fortune 50 companies to hundreds of thousands of small businesses in 135+ countries rely on FBA to grow and thrive. Today, FBA powers tens of billions in annual GMS across dozens of product categories.

But some of the largest, most valuable product categories remain structurally under-penetrated on FBA. Heavy and bulky goods, high-value electronics, multi-box furniture, and commercial B2B products represent hundreds of billions in addressable market — categories where customers and sellers want FBA but where seller economics, fulfillment architecture, and trust barriers have prevented adoption. These aren't emerging markets; they're established, proven segments where FBA's infrastructure hasn't yet caught up to demand.

We are building a team dedicated to solving these category-level structural barriers — redesigning fee architectures, building new fulfillment capabilities, closing cost-to-serve gaps against 3PLs, and earning seller trust at price points where every defect matters. This is a multi-year charter with leadership alignment, end-to-end ownership, and the mandate to work across organizational boundaries to deliver what no single team has been able to solve alone.

We operate with startup intensity inside Amazon — small teams, fast cycles, and the freedom to invent. Come build the systems that unlock FBA's biggest untapped opportunities.

Key job responsibilities
As an SDE-3 on this team, you will be a technical leader who owns the design and delivery of systems at the intersection of seller economics, fulfillment infrastructure, and category-specific growth:

- Design and build end-to-end systems that remove structural barriers to FBA adoption.
- Own the technical architecture for your domain, balancing speed-to-market with long-term scalability across FBA's global footprint
- Work across organizational boundaries — our charter includes alignment to make changes on partner teams' systems where needed to deliver the mission
- Translate complex business problems (cost-to-serve optimization, supply chain defect reduction, category-specific seller economics) into clean, scalable technical solutions
- Influence technical direction across the broader FBA platform by contributing design patterns, shared infrastructure, and experimentation frameworks that other teams adopt
- Mentor engineers on the team and shape engineering culture as we grow
