Data Engineer (m/f/d)

• Meter data integration. Connect industrial hardware and utility data streams into real-time dashboards. Every site is a little different, so a good part of the job is bringing data into a consistent structure across all sites
• Anomalies and insights. This is where data science comes in. Find the things in the data a customer would want to know about — a meter drifting, a machine left running overnight, consumption that does not fit the pattern — and turn them into something they can act on
• Tech stack and growth. Support the engineering team building scalable data pipeline

Must have:

• 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

Nice to have:

• 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

• Top-of-market team, flat hierarchy — work alongside people who push you to get better
• Competitive salary
• Full ownership from day one — you actively shape our company
• Close collaboration with our Product team
• Central office, easy commute — free lunch every Tuesday and Thursday
• Wellpass membership + Deutschlandticket sponsorship
• Regular 1:1s and retros focused on your growth
• Real impact — your work supports Europe's transition to a smarter energy system
