About the Role

You'll build the governed data foundation that replaces fragmented, siloed, and manually managed business functions on a modern stack, with architectural ownership and production delivery.

Responsibilities

  • Architect and own delivery of shared data products across Finance, People, Procurement, and Compliance, from design decisions through to production
  • Build and evolve the semantic layer that powers reporting, self-service analytics, conversational analytics, and Databricks Genie, writing the models, tests, and documentation that make it trustworthy
  • Design and build scalable data pipelines, data models, and governed data products using Databricks, dbt, SQL, and PySpark
  • Implement governance capabilities end-to-end, including Unity Catalog access controls, column-level security, data classification, lineage, and data quality standards
  • Drive DataHub adoption by defining metadata standards, lineage definitions, and data ownership models that make discoverability a first-class engineering concern
  • Translate complex and ambiguous requirements from senior stakeholders into production-grade data solutions, owning the problem from conversation to deployed model
  • Set the engineering standard for the team through the quality of your code, architecture decisions, and pull request reviews
  • Partner with the broader data team to continuously improve CI/CD, testing frameworks, observability, and data quality practices

Requirements

  • 8+ years of experience designing and building production data solutions, with a track record of leading complex technical initiatives end-to-end.
  • Track record of architectural ownership and designing end-to-end data solutions
  • Expert-level SQL and data transformation skills, with strong hands-on experience in dbt, PySpark, or both.
  • Design data products for scale, write tests without friction, and have clear opinions on where each tool's limits are
  • Deep experience with Databricks, Lakehouse architectures, or comparable modern data technologies, including Delta table design, Unity Catalog governance, compute trade-offs, and downstream BI or AI workloads
  • Experience implementing governance at scale, including access control, PII handling, column-level security, data lineage, and data quality management in production environments
  • Experience building trusted business-facing data products within Finance, People/HR, Procurement, Operations, or similar domains.
  • Understand business logic well enough to challenge unclear or incorrect requirements
