• Ensure rule execution is deterministic, versioned, stateless, and free from unintended side effects.

AI-Assisted & Agentic Engineering

• 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.

Testing, Reliability & 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

Collaboration & Technical Leadership

• 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., Success Metrics
• Action and policy services are stable, performant, and adaptable
• Database schemas facilitate correctness, efficiency, and full audit trails
