As a Senior Software Engineer on the Cards Experience EU team, you'll be a key technical contributor in building and evolving the core card spending experience within the Spend domain. You'll work alongside a team of experienced engineers across multiple European hubs, collaborating closely with staff engineers and cross‑functional partners to deliver complex, high‑impact initiatives in a fast‑moving environment.

The team is currently focused on several urgent strategic projects, and you'll play a hands‑on role in driving them forward — writing production code, shaping technical designs, and helping the team execute with quality and pace. You'll contribute to the technical direction of the platform and help navigate a highly specialised domain that includes card infrastructure, banking integrations, and complex flows of funds, balancing immediate delivery needs with long‑term platform sustainability and maintainability.

You'll bring strong technical judgement, a bias for pragmatic solutions,



and a genuine interest in the reliability and scalability of systems that customers across Europe depend on every day.

You will see how your technical decisions move the needle for our customers daily.

We prioritize autonomy and pragmatism, giving you the space to solve complex problems without unnecessary friction. Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a general platform.
