Senior Software Engineer, Backend (International)

About the Position

At Returnly, we exist for the moments that matter-giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most.

The Payments International Engineering team builds and operates the systems that enable bank and card payments across Returnly’s international markets. Based in Europe, with teammates across the UK, Spain, and Poland, we give customers familiar, local ways to pay, while building shared capabilities that make expansion into each new country easier.

Our work spans improving existing payment experiences and building the foundations for launches in new countries. We solve challenges across currencies and local customer needs, creating reusable solutions that support Returnly’s international ambitions. We work closely with product and engineering teams across Returnly, connecting the customer experience with the financial systems behind it.

We own our work from design through to production, combining the pace of international expansion with the reliability, security, and operational readiness that payments demand. Testing, monitoring, and supporting our systems are integral to how we build. As a growing team, we also shape the architecture, tools, and engineering practices that support this growth.

Joining Payments International means helping build the foundations of a global payments platform, with a direct connection between the systems we create and the customers Returnly can serve.
