Note: The job is a remote job and is open to candidates in USA. Humana is a healthcare company providing insurance and healthcare services. The Lead Decision Intelligence Engineer owns the application of Decision Intelligence and agentic AI across the NBA platform, modeling business decisions and building production-grade AI capabilities. The role also leads backend, microservices, database, rules-engine, testing, governance, and engineering-team efforts.
Responsibilities
- Analyze and formally model business decision processes, including objectives, constraints, policies, decision points, outcomes, dependencies, and feedback loops that govern member engagement
- Break complex business processes into decision graphs, decision services, decision hierarchies, and optimization opportunities that can be measured, automated, and improved
- Determine where rules, predictive models, reinforcement learning, optimization techniques, or agentic systems create the highest business value and operational impact
- Design and implement production agent workflows using LangGraph and LangChain, including multi-agent collaboration, tool usage, workflow memory, planning, reasoning, and human-in-the-loop approval patterns
- Build AI-powered capabilities embedded directly into the Action Library that assist users in creating, refining, validating, governing, and optimizing member actions
- Own integration with Azure OpenAI and other enterprise models through Humana's AI Gateway, including prompt engineering, structured outputs, retrieval patterns, tool calling, function execution, and workflow orchestration
- Design retrieval-augmented architectures using vector search, semantic retrieval, knowledge grounding, and enterprise content sources to provide reliable decision context
- Partner with data science teams to operationalize reinforcement learning and decision optimization models within NBA workflows, ensuring recommendations can be deployed and governed at scale
- Build rigorous evaluation frameworks that measure recommendation quality, decision quality, agent effectiveness, user adoption, business outcomes, and operational performance
- Implement guardrails, observability, traceability, policy controls, human review mechanisms, and auditability requirements appropriate for a healthcare environment
- Lead and mentor AI engineers, establish engineering standards, conduct design reviews, and drive execution across the Decision Intelligence workstream
- Work closely with product, business, decision science, data science, and engineering teams to convert complex decision processes into production AI capabilities
- 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
