Platform Engineer (m/f/d)

What we are buildingecoplanet builds the operating system for the energy transition. Our software helps European businesses cut energy costs, run more efficiently, and take the pain out of managing energy day to day. We are around 40 people and backed by EQT Ventures, HV Capital and others.Why This Role MattersYou build and run the platform the whole product sits on: the event streams, the backend services and the cloud infrastructure everything else is built on. Meter readings arrive from industrial sites across Europe, through messages or us accessing APIs. Your job is to make sure that traffic lands reliably, moves through the system in a shape other teams can build on, and keeps doing so as the number of sites grows.You join a team of 12 engineers in two squads. Small team, real ownership, and what you build reaches customers in weeks rather than quarters.What you will work onEvent streaming. Kafka is the spine of the system. You own topic and schema design, partitioning, retention and delivery semantics  and the everyday reality behind them: consumers falling behind, replays, backfills, late and duplicated readings.Backend services in TypeScript. The ingestion services, integrations and APIs around that stream. Every site is a little different, so a good part of the job is turning that variety into one consistent interface the product squads can rely on.Cloud infrastructure on GCP. Compute, networking, IAM, infrastructure as code, CI/CD and observability. The goal is a paved road: other engineers ship and debug their own services without going through you.Technical direction. You are senior enough to set it. Where we invest in the platform, what we standardise, what we deliberately leave rough for now  and bringing the rest of the team along with it.What Sets You Up for SuccessMust have:At least 6–8 years building and running backend systems in production, including real time in a platform or infrastructure role that other engineers depended onStrong backend en
