Senior C# Software Engineer – Manchester

The Engineering Challenge

Our Software Engineers don't just write code, they solve real financial problems for millions of customers. You'll work on distributed systems processing thousands of transactions daily, build resilient services that handle people's money, and create experiences that make traditionally complex financial products feel simple.

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.
