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.


Responsibilities

  • Join a cross-functional team with end-to-end ownership of a domain: design, build, deploy, operate, support.
  • Work on a platform that has been live and evolving for more than a decade.
  • Understand, extend, and safely replace systems that carry real business logic for real clients.
  • Use AI to build context on unfamiliar code, explore designs, generate and review implementations, and remove routine work.
  • Stay in the driver's seat: decide what to accept, what to challenge, and when the model is confidently wrong.

Requirements

  • Generalist by instinct; experience with more than one language or platform.
  • Experience running distributed, event-driven backend systems in production.
  • Ability to think in systems and design clear boundaries around complex banking domains.
  • Comfort in code you didn't write and ability to make your reasoning clear.
  • Experience using AI deliberately and knowledge of cloud infrastructure as code, CI/CD, and observability.

We Offer

  • Cutting-edge technology in fintech.
  • Highly qualified colleagues to learn from.
  • A friendly, multicultural environment where you can learn, grow, and make an impact.
  • Hybrid working setup with flexible hours.
  • Work from Anywhere policy.
  • Language classes and continuous learning and development.
  • Home office setup support.
  • Mental health and wellbeing support.
  • Weekly team lunches, wellbeing activities, and regular team events.
