• CI/CD exposure on Azure (Pipelines/GitHub), including test automation and deployment strategies for data & services
• Familiarity with secrets & access via Azure Key Vault, and role based access in data platforms (Unity Catalog/ACLs)
• Production mindset: on call readiness, incident response, and proactive post incident improvements to protect SLAs for a large consumer base
• Proven ability to design for reliability (idempotency, retries, transactional writes, schema evolution) and to operate at scale (performance & cost tuning)

Preferred Qualifications:

• Experience migrating mainframe data and workloads to cloud; healthcare claims domain exposure
• Experience with Azure DevOps governance and enterprise templates for JDs (tone/structure)
• Delta Live Tables, Structured Streaming, or Kafka ingestion patterns
• Data quality frameworks (expectations, unit tests), and lineage/catalog tools
