About the Role

We are looking for seasoned contractor architects to lead integration architecture for a healthcare digital platform connecting to external providers via custom REST APIs, FHIR-compliant endpoints, and complex authentication mechanisms. You will work alongside internal engineering teams to design secure, scalable, and compliant integration patterns — and bring a forward-looking perspective on AI-native and agentic architecture.

Core Responsibilities

• Design and own end-to-end integration architecture for external provider systems using custom APIs and FHIR R4/R5 standards.
• Define and implement authentication and authorization patterns including OAuth 2.0, SMART on FHIR, mTLS, API keys, and token exchange flows.
• Translate healthcare regulatory requirements (HIPAA, CMS Interoperability Rule, TEFCA, Da Vinci) into concrete architecture guardrails.=
• Evaluate and recommend API gateway, service mesh, and middleware patterns for health data exchange at scale.
• Architect agentic AI solutions — including LLM tool use, multi-agent orchestration, and RAG pipelines — within a healthcare compliance context.
• Partner with product, engineering, and security teams to produce Architecture Decision Records (ADRs) and integration blueprints.
• Conduct architecture reviews, identify risks, and define mitigation strategies across provider integration workstreams.

Must-Have Skills

• Deep expertise in FHIR R4/R5 — resource modeling, RESTful APIs, bulk data operations, and CDS Hooks.
• Hands-on experience designing custom API integrations with external healthcare providers (payers, PBMs, EHRs, benefits platforms).
• Strong command of modern auth patterns: OAuth 2.0, OpenID Connect, SMART on FHIR, JWT, mTLS, and API gateway security.
• Healthcare regulatory fluency: HIPAA Privacy/Security Rules, CMS Interoperability and Patient Access rules, 21st Century Cures Act.
• Experience with agentic AI architecture — LLM orchestration frameworks (LangChain, LlamaIndex), tool/function calling, multi-agent patterns.
• Proven track record delivering integration solutions at enterprise scale in health plan, PBM, or provider organizations.

Nice to Have

• Experience with Da Vinci Implementation Guides (PDex, CDex, PAS, Prior Auth).
• Familiarity with TEFCA / QHINs and emerging health information network standards.
• Exposure to CVS Health, Caremark, Aetna, or similar health plan/PBM ecosystems.
• Knowledge of CMS IAL2 identity assurance requirements.
• Cloud architecture experience on Google Cloud Platform or Azure in a healthcare context (HIPAA BAA in place).
• Prior work with benefits enrollment platforms (bswift, Workday Benefits) or HSA/FSA custodians.
• CMS Medicare integration experience — Medicare Advantage APIs, Part D data exchange, EOB/Claims resources via Blue Button 2.0, and CMS-mandated Prior Authorization API (CMS-0057).

Engagement Model

Embedded with internal engineering squads — not a hands-off advisory role.
Expected to produce artifacts: ADRs, integration blueprints, sequence diagrams, threat models.
Expected to build POCs and demonstrate capability to senior leadership
Collaborative with tech leads and principal engineers; able to mentor mid-level architects.
Direct access to product and engineering leadership for key decisions.
