About the project

Developers at Duco work as part of an agile, cross-functional, empowered engineering team. Each autonomous team owns the destiny of their part of the product and makes decisions jointly, alongside representatives from Product, Sales and other customer advocates. They don't just "code up" stuff that someone else specifies. Because where’s the joy in that?

You could be developing our award-winning reconciliation platform to meet future scaling requirements. Or building out our data prep (ingestion and transformation) product. Or maybe both, by helping refactor common components to a fully service-oriented architecture.

In terms of technologies, the ‘heavy lifting’ is mostly done in Java; web frameworks in use include Ruby on Rails and Spring Boot; and we utilise both MySQL and Clickhouse databases. It all runs in a cloud infrastructure which leverages Kubernetes, Docker and Helm. We also care very much about the developer experience, so we invest in the right tooling. Recently, that’s included projects involving Gitlab, Bazel and automation testing frameworks.

And across the stack, you should expect continuous diversification and development. We improve through innovation, so we welcome the impetus that new eyes and fresh perspectives can bring.

Your responsibilities

  • Designing and building new features, new services and new technologies

  • Ensuring the code you and your team deliver is supportable and highest quality

  • Working with Product Owners to understand customers and scope out work

  • Teaching and mentoring less experienced colleagues

Our requirements

  • A keen interest in writing resilient software that scales

  • Experience with one web framework (Spring Boot or Ruby on Rails)

  • Working knowledge of SQL and/or relational database concepts
