Senior C# Software Engineer – London
ZopaYou will design and evolve the services that power core banking products. The systems you help build process thousands of financial transactions every day. They must be scalable, resilient and secure. When money moves, it has to work. Every time.
But this role goes beyond implementation.
You will shape technical direction. Influence cross-team initiatives. Own complex, high-impact work from concept through to production. You will help decide not just how we build, but what we build and why.
This is senior in impact, not just title.
We’re growing across several of our product-engineering tribes at Zopa, with current opportunities in Current Accounts, Lending, Credit Cards and Product Enablement.
We care deeply about great engineering, which is why our core stack is Kotlin, running on a modern platform with Kafka, Kubernetes, Docker and AWS Aurora Postgres. But great engineers aren’t defined by a single language which is why we are agnostic with our hiring.
We want the right people, not the 'right' language, so if you come from a C#/.NET background, bring solid fundamentals, and have an appetite for learning something new, we’ll invest in you, help you grow your skills and confidently step into our Kotlin ecosystem.
Your impact:
-
Owning complex initiatives end to end, from idea to measurable outcome
-
Designing scalable backend systems that stand up to real-world scale and complexity
