• Build and own the Java/Spring services and REST APIs that expose the rules engine to the rest of the platform
• Produce and consume Kafka events to connect the rules engine to upstream signals and downstream decisioning and activation
• Write thorough tests for rule logic and services; treat rule correctness as a first-class, auditable concern
• Keep rule evaluation fast and predictable as the ruleset and traffic grow
• Run and participate in code reviews, uphold engineering standards, and ship production-ready code in a PHI-handling environment
• Partner with Product and compliance to turn business and regulatory requirements into clear, maintainable rules

• Hands-on experience with the Drools rules engine or another business rules management system (BRMS)
• Familiarity with front-end work (React/TypeScript) to support rule-authoring or admin interfaces
• Experience in healthcare, insurance, or another regulated industry where business rules encode compliance requirements
