  • 12–18 years of data engineering experience, including 8+ years with enterprise Data Warehouse and Data Lake platforms.
  • 5+ years of hands-on experience with Databricks and Spark at scale.
  • Strong expertise in modernizing legacy Cloudera platforms (CDH/CDP, Hive, HBase, Impala) to Databricks.
  • Deep knowledge of finance and risk data models, including General Ledger, sub-ledgers, and risk exposure models.
  • Experience implementing semantic layers for BI, reporting, and analytics with defined business metrics and KPIs.
  • Proficiency with cloud platforms (AWS or Azure) and CI/CD pipelines using Git, Terraform, Jenkins, or Azure DevOps.
  • Experience with orchestration tools such as Airflow or Databricks Workflows.
