Senior Full stack Engineer (Java&React) ALL LATAM

We're looking for a Senior Full-Stack Engineer to join a team working on a large E-commerce product catalog platform for a US company. The platform is business-critical, has a long history, and is now being modernized step by step. You'll work across the whole stack: backend services, APIs, databases and React UI.

What you'll do

• Build and ship catalog features end to end, from data model and API to UI
• Take part in the platform modernization: moving legacy parts to a modern architecture incrementally
• Write and maintain automated tests
• Work closely with Product and Design, and with engineers in the US, China and Latin America

What we're looking for

• 7+ years of software development
• Strong backend in Java (Spring Boot)
• Solid React experience, this is a real full-stack role, not backend-only or frontend-only
• REST APIs, microservices, PostgreSQL or MS SQL Server
• CI/CD and automated testing as part of your normal workflow
• At least one platform migration or modernization where you played a key role
• Daily use of AI coding tools (Claude Code, Cursor, GitHub Copilot) in real production work: for coding, tests, code review or documentation. We'll ask about specific examples, including where the tools got it wrong
• English that's comfortable for daily communication with a distributed team

Nice to have

• E-commerce, product catalogs or high-traffic consumer apps
• Experience with both .NET/SQL Server and a modern stack (Java, Go, Python, Postgres)
• AWS or Azure

What we offer

• 23 days of paid vacation
• 5 paid sick days
• Fully remote work
• Flexible schedule with a few hours of overlap with the US team
• Competitive compensation in USD
• Access to AI coding tools paid by the company (Claude Code, Cursor, Copilot)
• Equipment provided
• English classes with a teacher
• Direct communication with the client's engineering team, no long chains of managers
