Enterprise Solution Architect

Overview: The Enterprise Solution Architect (ESA) is the senior technical leader responsible for defining, governing, and evolving the enterprise architecture for a large-scale healthcare supply chain and logistics portfolio. The ESA leads the sustainment and modernization of legacy business applications, inventory systems, procurement systems, financial management integrations, enterprise data capabilities, and shared digital services. This role establishes the architecture for a centralized integration platform that enables secure, scalable, governed, and near-real-time information exchange across supply chain, logistics, clinical, financial, asset-management, and external partner systems. The ESA serves as the core technical leader responsible for planning, designing, and governing next-generation autonomous, goal-driven AI systems that support supply-chain modernization, operational decision-making, workflow optimization, enterprise data exchange, and intelligent automation. This position balances continuity of mission-critical operations with deliberate, phased modernization. The ESA ensures that architecture decisions improve interoperability, data quality, cybersecurity, resiliency, maintainability, delivery velocity, and readiness for future digital capabilities. This is a critical technical leadership role responsible for enabling a secure, integrated, resilient, and modern healthcare supply-chain ecosystem.
