Data Engineer (m/f/d)

About the role

What we are buildingAt ecoplanet, we're redefining energy for tomorrow. Our mission: turn energy management into the competitive edge every European business relies on to win its market. We're building the operating system for the energy transition — cutting energy costs, improving efficiency, and streamlining operations. Backed by EQT Ventures, HV Capital and more, and built by a team full of top-tier talent. Why This Role MattersYou will build and run the data backbone the whole product sits on. Meter readings arrive from industrial sites across Europe, through messages or us accessing APIs.

What they're looking for

✦ Select any requirement to ask Aptiora about your fit, evidence or application.

• At least 3–5 years in a data engineering role or something close to it, building pipelines other people depend on
• Hands-on data science experience. You do not need a research background. You do need to have built and evaluated models yourself: enough to tell a real anomaly from noise, to judge when a finding is solid enough to put in front of a paying customer, and to know what a pipeline owes a model running in production
• Solid with Python and SQL and cloud data infrastructure. You have designed and run pipelines, APIs and workflows in production
• Comfortable with high-volume time-series data: ingestion, data quality, backfills, and the everyday reality of late, missing and duplicated readings
• You think end to end before you go deep. When you hit a hard problem, the first instinct we want is “can a change somewhere else in the chain make this easy?” rather than heading straight into solving the hard version. A company our size cannot afford clever answers to problems that did not need solving
• Clear written and spoken English. German is a plus

Helpful, not always essential

• Energy, industrial, IoT or another domain where the data comes off real hardware
• Metering or device protocols, telemetry at scale, or streaming pipelines
• Knowledge of a second programming language, like TypeScript or Kotlin
• You run what you build: monitoring, alerting, and the occasional early morning debugging a pipeline
