Back-end Developer

Buildings generate data all day long. You make sure something smart happens with it: your code turns it into insights that owners of commercial real estate base their decisions on.

At Healthy Workers, you'll build our platform that uses AI and machine learning to map the energy use of every building, and turns it into clear insights. You'll work in a small team where your features matter from day one.

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're a scale-up. It's informal, lines are short, and you'll work closely with the founders every day.

You'll join our Product team and own features end to end, from an idea to running in production.

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 infrastructure

~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! Most of Kotlin will feel familiar quickly, and you'll learn the rest from colleagues who write it every day.

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.
