Description

Do you think like an engineer first, and a language specialist second?

We are looking for engineers who want to build the next generation of cloud-native financial technology.

Our platforms run on .NET and Java, but we are not looking for C# or Java developers (or Python developers, or developers of any other language). We are looking for software engineers, because what matters is that you can reason about distributed systems, become productive quickly in an unfamiliar codebase — including one written in a language you have not used before — and use AI as a real engineering partner rather than an autocomplete tool.

We build a cloud-native core banking platform that safeguards billions of euros of real customers' money. The bar for reliability, scalability, and security is exceptionally high, and we are continuously reinventing how we build software. If you want to help shape the future of engineering rather than watch it happen,



we'd love to talk to you.
Briefing

Ohpen launched the world's first cloud-native core banking platform. We don't just use technology — we build it, and we operate it in production for regulated financial institutions.

You'll join a cross-functional team with end-to-end ownership of a domain: design, build, deploy, operate, support. Not a ticket queue. Deployment is where the value gets delivered, so it isn't a step you hand to another team once the code is written. You'll be accountable for how your services behave in production, not only for how they look at code review.

You'd be working on a platform that has been live and evolving for more than a decade. A lot of the work is understanding, extending, and safely replacing systems that carry real business logic for real clients. The interesting problem here is not writing code quickly — that is now cheap. It is knowing what to change, what it will break, an
