Lead Data Engineer - NBA

Humana is a healthcare company seeking a Lead Data Engineer to own the NBA platform's data foundation on the Databricks Lakehouse. The role leads data platform architecture, pipeline engineering, feature platforms, streaming, governance, quality, and operational reliability while managing a small engineering team and partnering with data, AI, and platform teams.

Responsibilities:

• Own end-to-end delivery for the data engineering pod, including planning, execution, quality, and operational readiness
• Own the design and evolution of the NBA Databricks Lakehouse, including Bronze, Silver, and Gold layer standards, data lineage, and governance patterns
• Design, build, and maintain scalable batch and real-time pipelines that process member, clinical, claims, behavioral, engagement, and socioeconomic datasets
• Lead the design and operation of Gold-layer feature tables and reusable data products that support model training, scoring, reinforcement learning, and decision intelligence workloads
• Design and implement Kafka- and Spark Structured Streaming-based ingestion and processing patterns that enable near real-time decision-making
• Establish platform-wide standards for data validation, monitoring, lineage, reconciliation, alerting, and operational visibility; treat data quality issues as production incidents
• Drive optimization of Spark workloads, Delta Lake storage patterns, partitioning strategies, and query performance to support enterprise-scale volumes efficiently
• Ensure compliance with PHI, HIPAA, auditability, retention, and governance requirements through Unity Catalog, lineage tooling, and secure data management practices
• Lead and mentor engineers and contractors; conduct code reviews, establish engineering standards, and drive adoption of best practices across the pod
• Partner with Decision Intelligence, Data Science, AI Engineering, and Platform Engineering teams to ensure reliable, governed, and performant data delivery throughout the NBA ecosystem
• Architect, implement, and operate microservices that deliver: Action and variant metadata; Context-aware policy and eligibility evaluation; Versioned, read-optimized APIs for high-performance runtime consumption
• Guarantee that services are: Highly available, with low latency; Horizontally scalable for increased demand; Backward compatible to support safe evolution and upgrades
• Apply industry best practices for API design, schema evolution, service isolation, and secure integration
• Design, deploy, and maintain resilient database schemas to support: Comprehensive action and variant catalogs; Versioning, lifecycle management, and effective dating; Rule bindings and complex metadata relationships
• Select and operate appropriate data stores (relational, document, key-value) tailored to workload and scalability requirements
• Implement and monitor: Schema migration and backward compatibility strategies; Indexing and query optimization for performance; Data integrity, consistency, and reliability; Auditability and traceability for compliance and governance
• Integrate and manage enterprise-grade rules engines to support: Eligibility, constraints, and business policies; Suppression, cooldowns, exclusions, and other operational guardrails; Policy-driven allow/deny logic
• Work with technologies such as Drools (DRL/DMN), IBM ODM, DMN-based services, OPA/Rego, or similar
• Ensure rule execution is deterministic, versioned, stateless, and free from unintended side effects
• Utilize AI-powered and agentic tools to: Generate and refactor database schemas and service logic; Streamline rule authoring, validation, and ongoing refactoring; Detect and address conflicting or redundant rules early in the development cycle; Automatically produce comprehensive test cases and explore edge scenarios
• Apply AI responsibly to reduce manual effort while safeguarding clarity, correctness, and strong governance
• Develop automated tests for: Database migrations and schema changes; Service-level contracts and API backward compatibility; Rules behavior, precedence, and edge cases
• Ensure platforms are fully observable and resilient, featuring: Structured logging, metrics, and alerting; Clear error handling, fallback strategies, and robust incident management
• Support audit and compliance requirements through traceable and reproducible system behavior
• Work closely with platform, data, and machine learning teams to maintain clean integration points and shared standards
• Participate actively in architecture and design reviews to uphold platform quality
• Mentor junior engineers and contribute to technical standards and best practices

Requirements:

• Bachelor's degree in computer science or related field
• 7+ years of data engineering experience with at least 1–2 years in a lead engineer or technical leadership capacity
