DevOps & Data Architecture - Intern/Fulltime

Heidi Systems is building the data infrastructure layer for buildings and energy. We help property owners and managers digitize metering, consumption data, reporting and billing in one of Europe's largest and most outdated infrastructure markets.

We're hiring a senior engineer to own DevOps and data infrastructure. You'll be responsible for how our systems get built, deployed, monitored and kept running. And you'll make the architecture calls together with the founders.

What you'll own

• Our deployment pipeline and production environment, end to end (CI/CD, containers, servers)
• Monitoring, alerting and incident response, so problems show up before customers notice them
• Data ingestion and processing for meter, gateway and building data, including MQTT/IoT streams
• Database operations: Postgres setup, clustering, backups, performance
• Backend services in Go and TypeScript
• Validating and transforming high-volume device and consumption data
• Debugging real-world issues across gateways, MQTT, APIs and databases
• Internal tooling that automates our operations
• Architecture decisions with the founding team, plus the engineering standards the rest of the team builds on

Who we're looking for

You've run production infrastructure before and you know what breaks at 2am. You make decisions on your own, explain the trade-offs, and take responsibility for the outcome.

• Have several years of hands-on experience in
