The opportunity
At SumUp, we believe small merchants are the heartbeat of our communities. By joining the Global Bank tribe, you'll help shape the card infrastructure that directly powers how millions of merchants access, manage, and grow their finances in Brazil and beyond.
What you'll do
Shape the card domain globally: Take ownership of complex backend features across the card lifecycle, delivering production-ready code that scales across Brazil, Chile, and Europe.
Boost reliability: Introduce and improve monitoring, alerting, and runbook practices, actively support incident handling, and contribute to incident reviews with follow-up improvements that stick.
Drive technical growth: Define reusable architecture patterns, lead service refactoring, and reduce technical debt across 12+ service orchestrations in the Latam card domain.
Lead & mentor: Act as a technical reference for junior and mid-level engineers, facilitate design discussions, and author RFC sections that push the team's engineering standards forward.
Collaborate broadly: Partner with Product Managers, Designers, and cross-functional squads to shape roadmaps, influence technical strategy, and deliver compliant, merchant-facing products.
