Job summary

Arionkoder is hiring a Freelance Data Engineer to build the structured core of a governed data foundation on Databricks, ensuring entities are reconciled across systems and provenance is captured. You will enforce access control and provide APIs to serve data with caller permissions, while collaborating with a small client team.

You will work autonomously with business stakeholders, applying CI/CD for data and leveraging AI coding tools, while ensuring data quality and governance from the start.

Qualifications

• 6+ years of professional data engineering, building production-grade pipelines and data models.
• 3+ years hands-on with Databricks in production, including Unity Catalog.
• Expert SQL and Python: writes, debugs, optimizes, and refactors pipelines unaided. Spark/PySpark a plus.
• Strong data modeling, including history-aware techniques (SCD Type 2, effective dating, temporal validity), with provenance and lineage designed in from the start.
• Data quality and testing discipline: tests and expectations in pipelines (dbt tests, Great Expectations, or similar) and CI/CD for data.
• Reconciling data across systems: entity resolution or master data.
• Incremental and change-driven processing (CDC, streaming, or incremental frameworks) against freshness targets.
• Practical data governance: has implemented access control in production (row-level security, column masking, or role/attribute-based access) and knows where platform-level controls stop and application-level enforcement has to start.
• Has built APIs or services that serve data.
• Senior judgment: works autonomously, challenges unclear definitions, prioritizes by risk, owns outcomes without micromanagement.
• Daily use of AI coding tools (Claude, Cursor, or similar), with the judgment to know when to trust the output.
• C1 English; comfortable working fully remote and directly with a client team

Responsibilities

• Build the structured core of a governed data foundation on Databricks.
• Ensure business entities reconcile across systems with different identifiers and provenance.
• Enforce access control and provide APIs and MCP tools for data access.
• Collaborate with a small team and client data platform team; own components end-to-end.
• Apply AI tools to modeling, SQL, testing and documentation with sound judgment.
