Data Engineer
Viktor, Warsaw +1
What you need
- Metrics understanding. You understand what business metrics mean and how they are calculated. You reason about definitions, denominators, cohorts and segmentation, spot misleading comparisons, and connect metric changes to what is happening in the business.
- Strong Python engineering for ingestion, transformations and orchestration. You build, test and maintain reliable pipelines, not just notebooks.
- Agentic engineering is part of your daily workflow. You use coding agents to move faster while taking responsibility for correctness, maintainability and production behavior.
- Familiar with columnar warehouses (ClickHouse, Snowflake, BigQuery, Redshift). Bonus for ClickHouse, since that's what we're on.
- Built BI layers from scratch (Hex, Metabase, Looker). You know a dashboard that gets used from one bookmarked once and forgotten.
- Product mindset. Proactive, challenges assumptions, biases toward action.
- Founder mentality. You act like an owner of the function, not a ticket-taker in it.
- Munich or Warsaw.
Nice to have
- Experience taking ownership in a small, fast-moving team.
