The Company may adopt, vary or rescind these policies and directives in its absolute discretion and without any limitation (implied or otherwise) on its ability to do so Required Qualifications: Graduate degree or equivalent experience Cloud / Databricks / Snowflake Expert-level production experience with Databricks - Delta Lake, Unity Catalog, job orchestration, performance tuning at scale Solid production Snowflake experience - schema design, performance/cost optimization, and integration patterns between Snowflake and Databricks Deep cloud platform experience (Azure preferred) - storage, compute, networking, and security fundamentals as they apply to a data platform Experience as a technical lead - setting standards, doing architecture review, unblocking other engineers Proven track record owning Bronze/Silver/Gold or equivalent medallion-architecture pipelines end to end Leadership Proven to mentor without micromanaging; grows engineers rather than just directing them Proven comfortable being the technical voice in front of non-engineering stakeholders and leadership Judgment Experience working in a regulated or compliance-sensitive data environment (healthcare a strong plus) Proven pragmatic about technical debt and migration risk - knows when to stabilize vs. when to push forward Proven solid SQL and data modeling fundamentals underneath the tooling Preferred Qualifications: Direct healthcare, HEDIS, or claims data experience Experience leading a cloud migration from an on-prem or legacy platform (e.g., SQL Server) Experience scaling a data platform across multiple business units or regions Proven exposure to Databricks AI functions ( ai_summarize() , ai_classify() ) or supporting AI/ML pipelines downstream of the data layer Why This Role Apollo's cloud migration is under control and moving toward production stability, with active expansion interest from Optum West, East, and Mid-East regions. This role owns the data architecture that scale-out depends on, with direct visibility into leadership and real ownership over how the platform evolves.
