Full description
What you'll do
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.
- Shape the back-end architecture and write down the decisions, so nobody has to guess a year from now why something was built this way
- Get the platform ready for Europe: scalable, fast and reliable, from API to infrastructure
- Help build AI features that control building systems more intelligently
- Work with our Data team and SkySpark (our building analytics platform) to make Healthy Workers the single source of truth for all building and customer data
- Keep production healthy and the bug backlog under control
- Coach colleagues, review code within one working day and make sure no service depends on a single person
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.
