Software Engineer II – Expansion LATAM

Team description

Expansion LATAM is the engineering team behind SumUp's growth in Latin America, building and running the services for payments, onboarding, payouts, taxes and new market launches. The team started with Chile and is now taking what worked there to more markets, so the services need new features, reliable production support and more engineers who can deliver on their own. As a Software Engineer II, you'll work across several services instead of one product, make your own technical choices within the existing architecture, and see your changes help small businesses in new markets get paid.

What you'll do

• Build and maintain backend services for payments, onboarding, payouts and taxes, supporting new market launches

• Take changes from requirements to production, including testing, deployment and checks after release

• Choose practical technical approaches, explain the pros and cons, and suggest small design improvements

• Strengthen reliability by improving tests, monitoring and runbooks, and by reducing technical debt

• Investigate production issues using logs, metrics and traces, and lead reviews of incidents in assigned services

• Work with Product, Engineering and local teams to turn merchant needs into clear business rules

What you'll bring

• Backend development experience delivering changes independently in live services, with proficiency in Go or another backend language and the willingness to learn Go.

• Strong knowledge of relational databases, including data modelling, transactions and query optimisation.

• Solid understanding of APIs and distributed systems, including timeouts, retries and idempotency.

• Comfort with automated testing, CI/CD and code reviews, and the ability to investigate production issues using logs and monitoring tools.

• Ability to compare technical options, share progress, risks and blockers clearly in English with global teams, and judge when to decide independently and when to ask for help.
