  • Lead performance, reliability, and scalability efforts across the data platform, including monitoring, tuning, and optimization of pipelines and workloads.
  • Develop and maintain Databricks solutions leveraging Spark, Delta Tables, and managed workflows (jobs, orchestration).
  • Implement data governance and access controls using Unity Catalog and platform best practices.
  • Use Git-based version control to manage code, support peer collaboration, and enable CI/CD workflows.
  • Lead and support data platform migrations into Databricks, including legacy warehouse modernization and pipeline refactoring.
  • Mentor and train junior data engineers through code reviews, technical coaching, and knowledge sharing.

  • Strong experience with relational databases and advanced SQL, including schema design, joins, window functions, performance tuning, and query optimization-particularly in Amazon Redshift or comparable cloud data warehouses.
  • Proficiency in Python for data processing, automation, and pipeline development.
  • Deep hands-on experience with Databricks, including Spark optimization, Delta Tables, and Unity Catalog.
  • Experience migrating data pipelines and workloads into Databricks from legacy or cloud data warehouse platforms (plus).
  • Databricks certifications (e.g., Data Engineer Associate or Professional) a plus.
  • Proficiency with Git and version control best practices in a collaborative development environment.
  • Proven ability to mentor junior engineers and promote engineering best practices across the team.
  • Excellent communication skills, with the ability to clearly explain technical concepts to technical and non-technical stakeholders.
