• Define service decomposition, bounded contexts, and data ownership per service
• Design the event-driven backbone, including Kafka (or equivalent) domain event models, event schemas, versioning, and replay semantics
• Author OpenAPI 3.1 specifications for all inter-service and externally consumed APIs before Engineering builds against them
• Design the commercial insurance data model, including the Account → Applicant → Policy → Coverage → Location → Building → Unit/Exposure hierarchy and NAICS-specific exposure schema extensions
• Design the immutable Premium Transaction Ledger enabling full rating-factor-level reconstruction of every bound dollar across policy, coverage, location, building, exposure, carrier, and factor levels
• Enforce architectural separation between the stateless Rating Service (pricing only) and the Rules Service (eligibility, referral, and straight-through disposition logic)
• Design the Carrier Service abstraction layer supporting multiple carriers and quota-share allocation models
• Define integration architecture for SSO federation, AMS/clearinghouse connectivity, third-party data enrichment providers, and payment gateway integrations
• Drive non-functional requirements, including sub-second rating response times, 99.9% uptime, RPO ≤15 minutes, RTO ≤4 hours, and architectural governance standards such as immutable transactions, effective dating, and prohibition of cross-service database access
• Produce and maintain architecture artifacts, including C4 diagrams, ADRs, API contracts, and data models
