Title: Senior Engineer - Salesforce & Data Engineering

Location: Remote

Oak Street Health is a rapidly growing company of primary care centers for adults on Medicare in medically-underserved communities where there is little to no quality healthcare. Oak Street’s care is based on an entirely new model that is based on value for its patients, not on volume of services. The company is accountable for its patients’ health, spending more than twice as long with its patients and taking on the risks and costs of their care.

• Modernize legacy infrastructure by migrating on-prem SQL pipelines into scalable, cloud-native Databricks solutions using configuration-driven framework patterns (YAML, JSON).
• Establish DevOps & CI/CD standards across both Salesforce and Data Engineering domains using Infrastructure as Code (IaC) and Pipeline as Code methodologies.
• Define platform strategy and collaborate with upstream/downstream teams, IT, and BI to drive data quality, eliminate technical debt, and resolve complex architectural bottlenecks.
• Set technical standards and mentor engineers through rigorous design and code reviews, ensuring platform performance, security, and governance standards are met across teams.
• Serve as the highest-tier escalation point for complex production issues, pipeline failures, and system performance optimizations.
• Lead Medicare and payer-focused data initiatives involving member, claims, and operational datasets while ensuring strict PHI/PII compliance and regulatory standards (HIPAA).
• Create and maintain enterprise-grade documentation for platform architecture, data models, integration standards, and operational procedures.
• Other duties as assigned.

• Strong SQL and relational database background (e.g., SOQL, SOSL, MySQL, SQL Server, Oracle) with experience supporting and migrating legacy SQL environments to modern Python/PySpark architectures.
• Minimum 3+ years working experience with Salesforce custom development (Apex, Visualforce, LWC, web services - SOAP/REST) and Flow automation.
• Strong understanding of Medallion Architecture (Bronze, Silver, Gold) and building ingestion, transformation, and curation pipelines across all layers.
