DevOps & Data Architecture Intern

About Heidi Systems

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and managers digitize metering, consumption data, reporting, and billing workflows in one of the largest and most outdated infrastructure markets in Europe.

We are looking for an exceptional intern who wants to work close to the core of our technical system: data architecture, DevOps, infrastructure, and backend tooling.

This is not a classic internship. You will work directly on production-relevant systems, help shape our data infrastructure, and build tools that directly impact customers, internal operations, and the scalability of the company.

Tasks

What you will work on

Work on backend services in Go and TypeScript

Support the architecture of reliable data pipelines for meter, gateway, and building data

Improve internal DevOps workflows, deployments, monitoring, and system reliability

Work with configuration formats such as YAML and TOML

Help structure, validate, and transform high-volume device and consumption data

Build internal tools that make our operations faster and more automated

Support debugging of real-world infrastructure issues across gateways, MQTT, APIs, and databases

Work closely with the founding team on technical architecture decisions

Requirements
