Software Engineer, Backend Developer
I'm working with a long-established, consistently profitable online financial business that wants a software engineer for its three-person platform team. You'll run the platform behind 400+ C# microservices and write the code that makes life easier for the 30 developers who rely on it every day. This suits a developer who has moved towards infrastructure. You've built services commercially, and you've built and run things in AWS with Terraform.
The team are developers first, so your coding background counts for more here than years of pipeline scripting.
You’ll run the platform behind 400+ C# microservices and write the code that makes life easier for the 30 developers who rely on it every day. You’ll keep writing code, including C# services that process branches and hand releases to the testing service. You’ll know the friction developers hit because you've hit it yourself, and you’ll build the fixes. You’ll set requirements, decide how to meet them and choose what to tackle next.
Work splits roughly 50/50 between support and projects, from app work to the yearly Kubernetes upgrade, and the team moves on quickly when something more useful comes up. They want people who spot where it helps and bring it in
commercial developer experience, C#/.NET ideally, or Node.js/Type Script building and running it, ideally on AWS Infrastructure as Code (IaC), ideally Terraform hands-on, and keen to push them further you'll support around 30 engineers day to day
