Are you excited by the challenge of building systems that power every transaction in Latin America's fastest-growing e-commerce marketplace? We're looking for a Principal Engineer (PE) to define the technical strategy and architecture for 2 of our key charters as part of Amazon growth in Latin America technology team within International Emerging Stores (IES) Latin America.

In this role, you will be the PE for a large, multi-city engineering organization, owning the architecture across two interconnected domains — expansion of Amazon logistic domains for sellers (FBA) and retail — spanning multiple critical services (99.99% up time) and a broad portfolio of systems. You'll shape the technical direction for high-throughput systems processing government-mandated invoices at massive scale, supporting a rapidly growing marketplace with 30%+ year-over-year growth.

• Key job responsibilities
• You will lead the technical strategy for Brazil's Tax Reform — the most significant fiscal transformation in the country's history — impacting hundreds of systems across multiple technology organizations, with immovable government deadlines and zero tolerance for non-compliance. You'll architect solutions that allow Amazon's fulfillment network to significantly expand across Brazilian states, driving new capabilities in cross-docking, sub-same-day delivery, transshipment, and multi-Tax ID management.
• You will drive the migration from legacy systems to a modern event-driven platform, targeting substantial reduction in compliance implementation effort while maintaining zero downtime across dozens of use cases. You'll establish AI/GenAI strategies for engineering acceleration and set engineering standards across a rapidly growing organization.
• This role demands regular collaboration with senior technical and business leaders up to VP/SVP level, and cross-organizational influence across hundreds of engineers in multiple partner organizations including Tax Engine, GIS, SCOT, FBA WW, Amazon Fulfillment Technologies, ShipTech, and Transportation Finance Services. You'll work daily with world-class engineers across São Paulo, Belo Horizonte, Mexico City, Seattle, and Vancouver.
