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.
