As a Senior Data Engineer, AI & Agents, you will prepare enterprise domain data for consumption by AI agents, partnering directly with business stakeholders and subject-matter experts. The role centers on building and registering domain-grounded data agents over governed datasets, performing lakehouse migrations, and onboarding new data domains - including commercial, finance, research and development, and real-world data - onto the enterprise data platform. You will operate across Databricks and Snowflake, converting source tables to open formats and generating the catalogue metadata that powers downstream automation and data-contract workflows, all while ensuring high data quality, governed access, and reliable agent-based access to trusted data. The ideal candidate brings deep, hands-on data engineering expertise, strong governance instincts, and excellent stakeholder-facing skills. Key Responsibilities • Build and register domain data agents at scale over governed tables across Databricks and Snowflake. • Perform lakehouse migrations, including converting source tables to open formats (e.g., Apache Iceberg) to enable agent-based access. • Generate and curate catalogue metadata that feeds downstream automation and data-contract workflows. • Partner with business stakeholders and subject-matter experts through iterative build, test, and validation cycles. Qualifications • Bachelor's or Master's degree in Computer Science, Information Systems, Engineering, or a related field. • 5+ years of professional experience in data engineering, with significant hands-on experience across modern data warehousing and lakehouse platforms (Databricks and Snowflake preferred). • Strong data engineering background with genuine, hands-on fluency across both Databricks and Snowflake. • Demonstrated experience building data agents or query interfaces over governed datasets (e.g., Snowflake Cortex or Genie). • Advanced SQL together with Spark / PySpark, and experience with pipeline orchestration (dbt, Apache Airflow, or Databricks Workflows). • Experience implementing data quality, observability, and lineage, and applying governance controls such as masking and row- and column-level security. • Excellent stakeholder-facing skills, with a track record of translating business requirements into delivered data assets. Preferred Skills • Familiarity with MCP-based data exposure and with embeddings or vector search for retrieval-augmented use cases. • Experience with AWS and S3, in anticipation of onboarding native cloud data sources. • Experience with regulated life-sciences data domains (clinical, commercial, or real-world data). Technical Experience • Data platforms: Databricks, Snowflake (Cortex, Genie); AWS and S3. • Pipelines and modelling: SQL, PySpark, dbt, Airflow / Databricks Workflows. • Governance and catalogue: Unity Catalogue, Horizon, Collibra. • AI and agents: MCP; vector databases and embeddings. • Foundations: Python; YAML data contracts; Apache Iceberg; Git and CI/CD. Who you are • Agent-Oriented Builder: You enjoy turning governed datasets into reliable, domain-grounded agents that business users can query with confidence. • Quality-Focused: You are rigorous about data accuracy, lineage, and observability, ensuring high standards through validation before data reaches agents or the business. • Collaborative Partner: You thrive working directly with stakeholders and subject-matter experts through iterative build, test, and validation cycles. • Governance-Minded: You understand the critical nature of data security in regulated domains and proactively apply masking and row- and column-level controls. • Forward-Thinking: You are interested in the "big picture" of lakehouse architecture and open formats, eager to advance agent-based access patterns and best practices.
