apartmentHR-ON ApS placeOdense calendar_month 
Do you want to help shape a modern, scalable HR platform used by organisations worldwide?

At HR-ON we’re looking for a Senior Backend Software Engineer who enjoys building performant backend features and intuitive database structures.

What You’ll Do
  • Design and build core backend services in Node.js & TypeScript against a Postgres database.
  • Create and maintain complex database features using RLS, triggers, and PL/pgSQL programming.
  • Develop GraphQL endpoints that streamline frontend features.
  • Evolve the platform architecture for resilience, observability, and easy maintenance.
  • Collaborate with frontend, product, and DevOps peers to deliver features that add value for our users.

About You

You’re an experienced engineer who:

  • Writes production-grade Node.js/TypeScript.
  • Is fluent in SQL - from schema design to complex query optimisation.
  • Has worked on complex Postgres based solutions in the real world.
  • Uses GitLab (or similar) for version control and automated tests.
  • Has a solution-oriented attitude.
  • Thinks in terms of scalable, maintainable architecture and values knowledge-sharing with teammates.
Bonus Points
  • Experience working with existing code bases.
  • Optionally an interest in doing the odd frontend task in React/Typescript.
  • A fondness for type-safe, declarative coding styles (e.g. fp-inspired TypeScript).
Why HR-ON
  • High autonomy & influence over tech choices and ways of working.
  • Value-based self-management—trust, transparency, and flexibility come first.
  • Central Odense office with remote options; we still value regular in-person collaboration.
  • 50 passionate colleagues across Denmark, Germany, Norway, and Japan, united by a flat structure and meaningful work.
