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and managers digitize metering, consumption data, reporting, and billing workflows in one of the largest and most outdated infrastructure markets in Europe.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 a skilled frontend engineer who wants to own the product layer that makes complex infrastructure data legible, actionable, and fast. You will work directly on our SvelteKit application — the interface through which property managers, operations teams, and customers interact with our systems every day.

This is not a typical frontend role. You will work with real data from real buildings, build tools that handle high-volume consumption data, and collaborate closely with backend engineers and the founding team. You own what you build.
