Cloud Architect

T-Rex is seeking a Cloud Architect to support the Joint Operational Medicine Information Systems (JOMIS) portfolio within the Defense Healthcare Medical Systems (DHMS) program. This role is responsible for defining, implementing, and governing cloud architecture patterns that support operational medicine systems across development, test, and production environments. The Cloud Architect provides technical leadership to ensure JOMIS platforms are secure, scalable, reliable, and aligned with government standards and mission needs.

The role works closely with engineering teams, cybersecurity, Dev Sec Ops , and program leadership to establish clear cloud standards, guide modernization efforts, and ensure consistent implementation across vendors and delivery teams.

The Defense Healthcare Management System is transforming the delivery of healthcare and advanced data sharing through a modernized electronic health record for service members, veterans and their families. The Workforce 3.0 program within DHMS is a managed solution that leverages innovative processes and best‑in‑class methodologies from the private sector to enable the entire PEO DHMS workforce to deliver world‑class technology. The DHMS systems provide important health IT capabilities to 9.6 million active‑duty military, their families, and their beneficiaries.

This program supports management of technical deployments, field deployments, and technology training/adoption.

• Lead cloud architecture design for JOMIS platforms and systems, including reference architecture, landing zone standards, environment design, and network segmentation.
• Define cloud hosting and connectivity approaches that support operational medicine systems, enterprise users, integrations, and deployed environments.
• Document, propose, and pressure‑test solution design options for cloud hosting and optimization, including clear tradeoffs, recommended courses of action, and decisions to be made.
• Drive reliability and performance practices, including scalability planning, resiliency patterns, disaster recovery strategies, and uptime targets.
• Support modernization efforts by contributing to legacy system migration planning, transition architectures, and phased implementation roadmaps.
• Partner with cybersecurity teams to ensure architectures align with Zero Trust principles, identity‑based access, encryption, auditing, and continuous monitoring requirements.
• Establish and maintain cloud governance practices, including architecture review processes, technical standards, and reusable patterns across teams and vendors.
• Guide Dev Sec Ops  platform architecture, including CI/CD pipelines, infrastructure as code, automated compliance evidence, and environment promotion strategies.
• Provide clear and concise briefings to government and BCG leadership on cloud architecture decisions, risks, tradeoffs, and delivery impacts, along with a perspective on recommended courses of action.
• Develop and maintain architecture documentation, including system context diagrams, deployment views, interface mappings, and DoDAF‑aligned artifacts when required.

• Bachelor's degree in computer science, Information Systems, Engineering, or a related field, or equivalent practical experience.
• Eight or more years of experience in cloud architecture, platform engineering, or enterprise infrastructure roles.
• Demonstrated experience designing secure cloud or hybrid environments in regulated or compliance‑driven organizations.
• Demonstrated experience modernizing legacy and monolithic architectures into cloud‑native or microservices‑based architectures (containers, managed services, event‑driven patterns as appropriate).
• Experience developing cloud migration strategies and executable plans (discovery, dependency mapping, landing zone readiness, wave planning, cutover/rollback, validation, and decommissioning).
• Strong understanding of networking, identity and access management, secrets management, logging, monitoring, and incident response integration.
• Hands‑on experience with Dev Sec Ops  concepts, automation, infrastructure as code, and CI/CD pipelines.
• Familiarity with DoD system development…
