Internal Data Engineer (m/w/d)

• Pipelines: You connect our source systems — CRM (Pipedrive), product databases, finance systems, third-party APIs, hotel systems (Opera, SIHOT, Delphi). Ingestion, scheduling, error handling.
• Modelling: You build the transformation layer (dbt or equivalent): properly versioned, tested, documented. Staging → core → marts.
• Metrics layer: One definition per metric. You permanently end the “but my spreadsheet says 4.2” conversation.
• Data quality: Tests, freshness checks, alerting. You notice a broken pipeline before the CFO does.
• Enablement: You build models so that business teams can work self-service in the BI tool. You are not a dashboard butler.
• Reporting support: You provide the reliable data foundation for C-level and investor reporting — Finance handles interpretation.

• 3+ years as an Analytics Engineer, Data Engineer or BI Engineer with a strong modelling focus.
• Expert-level SQL. Not “I can do joins” — window functions, incrementality, performance.
• Experience with dbt — or a convincing explanation of how you solved it differently.
• Python for ingestion and automation.
• Experience with at least one warehouse: BigQuery, Snowflake, Redshift or Postgres-based.
• Git, code review, tests, CI. Your data models are software, not a hobby project.
• You talk to business teams and translate “can you pull me a report” into a data model.

• You have moved CRM data (Pipedrive, HubSpot, Salesforce) into a warehouse before — including the joy of historically grown custom fields.
• Experience with orchestration (Airflow, Dagster, Prefect).
• BI tooling: Metabase, Looker, Power BI.
• GDPR awareness when handling personal data — not a side note for us.

What we offer

• Work with real AI technology at international level — not as a pilot project, but as our business model.
• Genuine room to shape things. Your ideas do not land in a suggestion box; they land in the next iteration.
• A short path to the management team. Decisions take days, not committee rounds.
• Growth you are part of. We are building the company’s next chapter — with roles, responsibility and prospects that did not exist a year ago.
• Leipzig as your primary base, with regular time in the office and flexible remote work. Hybrid models are everyday practice here, not the exception.
• Permanent contract, full-time.
• Performance bonuses for demonstrable results.
• Multi-day team events in places that are actually fun.
