Summary
A Senior Backend Engineer at SumUp designs scalable payment systems for Brazilian merchants, owns architecture and RFCs, writes production-grade Go/SQL code, and mentors a cross-functional team while optimizing CI/CD and technical standards.
At SumUp, we believe small merchants are the heartbeat of our communities. By joining the Payments BR Tribe, you'll help shape solutions that directly solve merchants' everyday challenges and redefine how financial products empower entrepreneurship in Brazil. The tribe is deeply focused on the Brazilian market — understanding the real needs and behaviours of our merchants and building products that truly fit their world. You'll be part of a global, autonomous, cross‑functional team of driven, purpose‑led people who take ownership, embrace challenges, and care deeply about helping businesses succeed.
What you'll do
Own the architecture: Design and author RFCs that shape how the domain evolves, driving clean, scalable solutions across our integration layer with internal SumUp services and third‑party services as well.
Write and review high‑quality code: Take full ownership of backend delivery — from writing production grade code to leading rigorous peer reviews that keep the codebase healthy and maintainable.
Drive technical standards: Establish clear documentation, testing practices, and CI/CD improvements that reduce technical debt and make the squad more autonomous over time.
Mentor and grow the team: Pair‑program with and actively develop other engineers on the squad, acting as the technical reference point and fostering a culture of ownership and engineering excellence.
Collaborate broadly: Partner closely with the Engineering Manager, Product Manager, and cross‑functional stakeholders to translate business needs into clear technical roadmaps and scalable solutions.
What makes you a great fit
Solid backend development skills, with experience in Go, or strong experience in functional backend programming languages with a genuine drive to master Go quickly. Strong expertise in code design, automated testing, CI/CD, performance optimisation, and building resilient, well‑architected systems. A track record of leading technical projects end to end — from writing design documents to shipping production improvements that hold up at scale. Hands‑on experience with AWS Cloud services and strong SQL optimisation skills with relational databases. Have advanced English proficiency, with the ability to present and discuss technical topics clearly across teams and with non-technical stakeholders. Experience contributing to technical strategy beyond the immediate squad.
