Senior Java Developer

As a Senior Java Developer within the Back Office Tech Team of Nedap in Healthcare, you work on the technical foundation of the largest product in the Ons® Healthcare landscape: Ons Administration. Your team supports the three domain teams that build this product on a daily basis. The mission? Continuously improving the application platform to structurally increase developer happiness across all teams.

In recent years, we have upgraded Java from version 8 to 21, modernized our application framework, and migrated our CI/CD pipeline from Jenkins to GitHub Actions. We are also working on major architectural revisions to make Ons Administration future-proof.

The biggest challenge in the coming year? The transition from a single-tenant, bare-metal environment to a multi-tenant, high-availability container platform. From session management to disk storage and background jobs—everything is being rethought. All of this while our software is used daily by thousands of healthcare professionals across the Netherlands.
