About The Position

The Enterprise Solution Architect (ESA) is the senior technical leader responsible for defining, governing, and evolving enterprise architecture for a large-scale healthcare supply-chain and logistics portfolio. The role leads sustainment and modernization of legacy business applications, inventory and procurement systems, financial-management integrations, enterprise data capabilities, and shared digital services. It establishes the architecture for a centralized integration platform supporting secure, scalable, governed, near-real-time information exchange across supply-chain, logistics, clinical, financial, asset-management, and external partner systems.

The ESA plans, designs, and governs next-generation autonomous, goal-driven AI systems supporting supply-chain modernization, operational decision-making, workflow optimization, enterprise data exchange, and intelligent automation. The role balances continuity of mission-critical operations with phased modernization, ensuring architecture decisions improve interoperability, data quality, cybersecurity, resiliency, maintainability, delivery velocity, and readiness for future digital capabilities.

The ESA establishes enterprise architecture governance and roadmaps; defines integration, data, cloud, security, and modernization patterns; and partners with product, engineering, security, data, operations, and business teams to translate strategy into delivery plans and measurable outcomes. The position is remote in the USA and requires the ability to obtain a Tier 2 / Moderate Risk Public Trust and a VA PIV credential. The suggested pay range is $210,000–$250,000; some positions may be eligible for additional compensation such as bonuses.

TISTA describes its work as meaningful and mission-driven, with supportive leadership, learning opportunities, and internal mobility. Benefits include healthcare coverage, remote working options, paid time off, training and certification opportunities, healthcare and flexible savings accounts, paid life insurance, short- and long-term disability, 401(k) match, tuition reimbursement, an employee assistance program, paid holidays, military leave, and more.
