Were Looking For a Senior Data Engineer (DBT + Spark + Argo)

In this role, you will be at the core of a strategic data transformation initiative: converting monolithic SQL Server logic into a modular, testable DBT architecture, while integrating Spark for performance and Argo for orchestration. You will work with cutting-edge lakehouse formats like Apache Hudi, Parquet, and Iceberg, and enable real-time analytics through ElasticSearch integration.

If you're passionate about modern data engineering and want to work in a data-driven, cloud-native, healthcare-focused environment, this is the role for you.

What Youll Be Doing

• Translate legacy T-SQL logic into modular, scalable DBT models powered by Spark SQL
• Build reusable and performant data transformation pipelines
• Develop testing frameworks to ensure data accuracy and integrity in DBT workflows
• Design and orchestrate workflows using Argo Workflows and CI/CD pipelines with Argo CD
• Manage mock data and reference datasets (e.g., ICD-10, CPT), ensuring version control and governance
• Implement efficient storage/query strategies using Apache Hudi, Parquet, and Iceberg
• Integrate ElasticSearch for analytics by building APIs and pipelines to support indexing and querying
• Collaborate with DevOps teams to optimize S3 usage, enforce data security, and ensure compliance
• Work in Agile squads and participate in planning, estimation, and sprint reviews
