About the opportunity We are seeking a talented Senior Backend Engineer to join the Platform Engineering Domain in the Experimentation team…
In the Global Bank tribe, we are building the infrastructure and core services needed to provide our merchants with a digital bank account that empowers them to be successful at doing what they love. Our goal is to become the most popular banking partner for small merchants globally by offering a high-quality banking experience tailored to their needs—effortless, simple, and affordable.
Joining the Global Bank tribe means playing a key role in helping us build SumUp's digital bank. You’ll collaborate with a global, autonomous, cross-functional team that refines an aspect of our product from concept to execution. Work alongside colleagues from 32 nationalities across Cologne, Berlin, São Paulo, Sofia, London and Vilnius, united by a shared commitment to taking ownership, working with purpose, and helping small businesses thrive.
As a Senior Backend Engineer, you will play a key role in helping us transition from a localized setup with regional banks to a unified Global Bank. A significant challenge will involve supporting the move to a fully distributed, event-driven architecture.
Our tech stack includes Go, AWS, Kafka, PostgreSQL, and Kubernetes, supported by a strong observability toolchain with Prometheus, Grafana, and Honeycomb. We also actively use AI‑assisted development tools such as Cursor, GitHub Copilot, and others.
SumUp’s engineering culture is built around ownership. We follow a “build it, run it, improve it” model, with strong observability and a focus on learning. Engineers have clear scope and autonomy, with decisions documented, reviewed, and made collaboratively.
The Vilnius team is a core part of the Global Bank domain. We own production systems, shape technical direction, and work closely with colleagues across SumUp’s global offices on critical merchant banking capabilities. Join our Vilnius Team today (Vilnius office).
