Senior Data Platform Manager H/F

We are building the Bull Enterprise Data Hub a centralized data platform that consolidates product data across 8+ source systems (SAP, Hotspot, Windchill) into a unified, versioned, API-first platform.

The platform powers:

• HPCCAT product catalog for HPC, AI & Quantum
• Executive dashboards GATE program KPIs, S&OP forecast, roadmap views
• Machine-to-machine integrations REST APIs consumed by quoting, digital twin, and external tools You will join a small, high-impact team (3 people) and own the data engineering layer: ingestion pipelines, transformation models, data quality, and warehouse infrastructure.

What You’ll Do

• Build and maintain ETL/ELT pipelines to ingest data from SAP, HotSpot, vendor feeds, and internal databases
• Design and implement dbt transformation models (staging intermediate marts) on PostgreSQL and DuckDB
• Ensure data quality implement tests, monitoring, anomaly detection, and reconciliation with source systems
• Develop and extend the REST API (FastAPI/Python) for data access by downstream applications
• Manage infrastructure Docker Compose, PostgreSQL 16, Alembic migrations, CI/CD
• Collaborate with Product Managers to understand data needs and translate them into reliable data models
• Document data models, lineage, and operational runbooks
