Descrição da vaga

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.

As a (Senior) Backend Engineer, you'll be the technical anchor of a small, high-impact squad — bringing clarity to complex integration logic, setting the architectural direction, and helping a growing engineer reach their potential. This is a role for someone who finds satisfaction in making hard systems reliable, loves writing clean Go code, and isn't afraid to navigate the complexity that comes with building at scale in a fast-growing market.

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
