  • Drive adoption of AI tooling and agentic workflows within the data engineering team
  • Ensure data quality, observability, and reliability across all pipelines and platforms
  • Develop self-service tooling and microservices to simplify platform usage for other teams

  • Solid understanding of ETL/ELT patterns, data modelling (dimensional, Data Vault), and data warehousing
  • Experience with orchestration tools (Apache Airflow, Azure Data Factory, or equivalent)
  • Knowledge of Infrastructure as Code (Terraform or equivalent)
  • Understanding of production-grade system requirements: reliability, scalability, observability, and performance
  • Upper-Intermediate English level

WILL BE A PLUS

  • Familiarity with RAG pipeline design and LLM integration patterns
  • Knowledge of data governance frameworks and tools (Unity Catalog, Apache Atlas, or similar)
  • Experience with dbt for data transformation and modelling
  • Familiarity with MLflow, Feature Stores, or ML platform integration
