Platform Engineer (m/f/d)

• 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 on
• Strong backend engineering in TypeScript. You have designed, shipped and operated services and APIs in it — not just touched it around the edges of a frontend
• Hands-on with Kafka in production. Topic design, consumer groups, ordering and delivery guarantees, and what you actually do at 3am when a consumer group is hours behind. A comparable streaming platform is fine if you know it at that depth
• Solid on GCP or an equivalent cloud: containers, networking and IAM basics, infrastructure as code, CI/CD, monitoring and alerting. You have owned infrastructure, not just deployed onto it
• Comfortable with high-volume time-series data: ingestion, data quality, backfills, and the everyday reality of late, missing and duplicated readings
• You have seen a few things. Enough production years behind you to know which trade-offs come back to bite, when the boring option is the right one, and how to make a call with incomplete information instead of waiting for certainty
• Kubernetes knowledge at the level of running it, not only deploying to it.
• Clear written and spoken English. German is a plus
• 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 Python, Go or Kotlin
• You run what you build: monitoring, alerting, and the occasional early morning debugging a pipeline
