Careers / Principal software engineer (AI and DevOps)
Set how we build with AI.
Keep it running in production.
You are our most senior software engineer. You set how we build with Claude and other AI coding agents, own the architecture of the platform, and run what we ship: builds, deployments, data and security.
Full-time · Espoo, Finland
What you will do
- Set how AI coding agents work in our codebase: what they may change, how their work is tested and reviewed, and where a person decides.
- Design how AI works inside the product: a model prepares a proposal, engineering code calculates and checks it, and a person authorises release.
- Write and review the code that generates and checks designs, and exports them in formats other vendors’ tools open: IFC, DXF and what each customer needs.
- Own the architecture: TypeScript on Cloudflare Workers, with Python and containers where engineering checks need them.
- Run the pipeline: automated tests, deployments, database migrations, monitoring and cost.
- Keep each customer’s data separate and access controlled, and lead the response when something breaks.
What you bring
- Many years of software engineering, including systems you designed and then ran in production.
- Deep daily use of Claude Code or similar agents, and products you have built on the Claude API or another model API.
- DevOps you have done yourself: CI/CD, infrastructure as code, monitoring, security and incident response.
- Interest in how things are designed and built: CAD, structures, plants or machines.
- English; Finnish is a plus.
