Responsibilities
- Establish and maintain deterministic behavior in the decision pipeline from context input through rule processing, scoring, reconciliation, and final response generation.
- Manage rule sets, reason-code hierarchies, model iterations, and objective settings to enable full decision transparency, including human-readable justifications, policy citations, and model identifiers.
- Enforce contact policies such as consent rules, quiet periods, frequency limits, and real-time suppression triggers to ensure all communication channels comply with regulatory and business standards.
- Architect comprehensive traceability across systems, linking data flow and causality between the Decision Engine, Rules engine, Action Library, State Machine, Outbox, and channel execution components.
- Build immutable decision logs containing input summaries, context fingerprints, model and rule versions, and explanations, with cryptographically verifiable replay capabilities for auditing.
- Implement semantic validation layers to identify and flag business logic anomalies, such as prohibited channel promotions, going beyond standard infrastructure monitoring.
- Deploy OpenTelemetry-based observability; create operational dashboards tracking key metrics like response latencies (p50/p95), rule rejection patterns, model inference times, cache efficiency, and replay system health.
- Construct automated determinism testing frameworks using golden datasets to confirm consistent outputs across identical inputs and system versions, integrated into continuous integration and deployment workflows.
- Ensure interface compliance for Next Best Action services through OpenAPI specifications, schema enforcement, and consumer-driven contract testing across all platform components.
- Apply property-based testing methodologies to validate rule logic, scoring accuracy, and reconciliation outcomes under diverse policy and event conditions.
- Automate performance and fault tolerance validations, including timeout configurations, circuit breaker patterns, fallback mechanisms, and chaos engineering, to uphold p95 service level objectives.
- Preserve explanation quality through regression safeguards that prevent degradation due to changes in rules or machine learning models.
- Partner with policy and rules teams to assess reason-code coverage and conduct pre-deployment simulations and backtesting.
- Collaborate with machine learning teams on model lifecycle management, feature consistency between training and production, latency targets, and gradual rollout techniques like shadowing and canary releases.
- Coordinate with state management and outbox services to guarantee exactly-once processing semantics, idempotent message handling, valid state transitions, and invariant enforcement.
- Support integration and orchestration requirements for Node.js and TypeScript-based interfaces as needed.
