👉 Senior Data Platform Engineer (AWS)

🟣 You will be:

• Designing and provisioning the lakehouse foundation on AWS: S3 lake zones (raw, canonical, curated), Apache Iceberg tables, Glue Data Catalog, Athena, and Lake Formation,
• delivering all infrastructure as code with Terraform, reproducible from the client's GitHub repositories and CI/CD, across isolated environments (ci, dev, staging, prod),
• building and enforcing the tenant-isolation security gate: Lake Formation row-level security and physical partitioning by CompanyId, separate IAM roles for customer versus internal access, and fail-closed handling that quarantines and alerts on rows with missing or unresolved CompanyId,
• implementing the upstream entitlement mapping (principal to allowed CompanyIds) that drives access control,
• seting up ingestion infrastructure: CDC paths from DynamoDB Streams, AWS DMS extracts from Aurora PostgreSQL, and bulk export to Parquet, supporting the near-real-time (5 min) and batch (4 hr) SLAs,
• standing up workflow orchestration with Apache Airflow and Astronomer Cosmos, including profile-based connections, model-level retries, and lineage emission,
• building CI/CD pipelines (GitHub Actions): dbt compile and slim builds, SQLFluff linting, DAG validation, branch protection, environment promotion, and Git-revert rollback,
• configuring end-to-end governance and observability: catalog and data contracts, OpenLineage capture, and org-wide audit through CloudTrail,
• owning cost governance and monitoring: resource tagging, usage alerting, and right-sizing of compute,
• collaborating with the Data Platform Architect, Data Engineers, and Analytics Engineer, and support knowledge transfer to the client team.

🟣 Your profile:
• strong experience with AWS data and platform services: S3, Glue (Data Catalog and Jobs), Athena, Lake Formation, IAM, VPC networking, DMS, DynamoDB, Aurora PostgreSQL,
• experience with infrastructure as Code with Terraform, including modular design and YAML-driven configuration,
• knowledge about Apache Iceberg and open table formats on S3,
• experience with security and access control,
• knowledge about CI/CD engineering with GitHub Actions, trunk-based development, and environment promotion,
• solid Python and SQL skills,
• experience with dbt on AWS (dbt-athena, dbt-glue adapters) and analytics-engineering workflows,
• previous exposure to Airflow orchestration, ideally with Astronomer Cosmos,
• data lineage and observability (OpenLineage, dbt-elementary) and data quality tooling (dbt tests, dbt-expectations) skills,
• experience with CDC and streaming ingestion patterns.

Work from the European Union region and a work permit are required.
