Java Backend Engineer

As a Senior Java Backend Engineer Utrecht, you work on the core of the platform: a configuration-driven workflow and data platform on which other teams build their domains. You develop software tooling and services that are directly used by internal engineering teams to build faster, safer and more consistently.

You’ll tackle challenges around flexibility, scalability and reliability. Think about how domain logic is expressed through configuration, how mappings remain correct as the system grows, and how to design a platform that can be used by multiple teams simultaneously without introducing unnecessary complexity.

In addition, you collaborate closely with other teams across the organisation. You help them model their use cases, understand their needs and translate these into reusable, generic solutions within the platform.

Your employer: Mid-sized tech company building the backbone for critical systems in the Netherlands

This mid-sized tech company based in the Utrecht region is building a multi-tenant SaaS platform that acts as the backbone for essential processes affecting millions of people. Think large-scale data flows, strict reliability requirements and 24/7 availability. You’ll be working on software that is not only technically challenging, but also directly impacts how systems operate at scale.

The platform has recently been built from scratch: modern, clean and without legacy constraints. The foundation is in place, the first customers are being onboarded, and now the next phase begins: scaling, expanding and continuously improving the platform. This includes performance optimisation, new functionality and integrating AI into both the product and the way of working. For you, this means joining at a point where you can still have significant influence on the technical direction.

The culture is strongly engineering-driven. You’ll work with experienced engineers who see best practices, DevOps thinking and clean code as the standard. AI is actively leveraged to improve productivity and quality. This is an environment where modern software engineering is truly lived and where you’ll be continuously challenged to grow.
