Responsibilities

Evolve platform architecture across services, data, events, APIs, and infrastructure - refining patterns for resilience, scalability, consistency, and performance that teams apply across the system

Drive event-driven architecture including messaging patterns, event choreography, contract and schema governance, and integration strategies

Shape FHIR and health data architecture including resource design, data modeling, query patterns, and performance optimization for a healthcare data platform operating at scale

Participate in architecture reviews as part of the Architecture team’s approval process for significant designs and initiatives, applying consistent review criteria and ensuring designs meet platform standards before implementation. Document decisions as ADRs that guide future work

Develop reusable patterns and guardrails through reference architectures, design templates, and concrete examples that make it easy for teams to apply platform patterns

Stay technically credible by reviewing code, building reference implementations when needed, and using operational data to validate architectural decisions
