Back-end Developer

A few years from now, our platform will run in buildings across the whole of Europe. How the back-end underneath it is built, is decided by you.

You'll join the market leader in AI SaaS for commercial real estate as a senior, right as we roll out to Belgium, Luxembourg and Germany. Your architecture decisions won't disappear into a committee: they become the foundation the whole team builds on.

Healthy Workers is an Amsterdam-based AI SaaS scale-up and the market leader in building optimisation for commercial real estate. Owners of commercial real estate are under real pressure to make their buildings more sustainable. Our platform helps them do that: we connect to the installations in buildings and collect data in order to make them run smarter, using less energy and giving people more comfort. We work directly with those owners. After the Netherlands, we're now rolling out in Belgium, Luxembourg and Germany, with the rest of Europe next.

We are informal, lines are short, and you'll work closely with the founders every day.

You'll join our Product team as the senior on the back-end. You build alongside the team, and you make sure both the team and the platform are ready for the next stage of growth.

What your week roughly looks like:

~60% building: APIs, data models, integrations and AI features

~20% maintenance, devops and infra: bugs, monitoring, CI/CD and scalability

~10% code reviews and security (pentests and ISO)

~10% stand-ups, refinement, sprint planning and retros

Our stack

Kotlin, Micronaut, MySQL, BigQuery, Docker, Kubernetes, GitLab CI, Terraform, Google Cloud Platform and SkySpark. We plan in Linear.

Coming from Java? Perfect! Kotlin will feel familiar quickly, and with your JVM experience you'll be up to speed within a few weeks.

The process

From first conversation to decision takes 2 weeks at most. After every step, you'll hear back from us the next day. No weeks of silence.
