Marathon TS is seeking a JOMIS 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, DevSecOps, and program leadership to establish clear cloud standards, guide modernization efforts, and ensure consistent implementation across vendors and delivery teams.

JOB RESPONSIBILITIES:

• 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 solution designs including clear tradeoffs, recommended course(s) 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 DevSecOps 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 course(s) of action
• Develop and maintain architecture documentation, including system context diagrams, deployment views, interface mappings, and DoDAF-aligned artifacts when required

BASIC JOB REQUIREMENTS:

• 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 respons e integration
• Hands-on experience with DevSecOps concepts, automation, infrastructure as code, and CI/CD pipelines
• Familiarity with DoD system development lifecycle practices and architecture frameworks such as DoDAF
• Ability to produce clear technical documentation and communicate effectively with technical and non-technical stakeholders
• Hands-on architecture experience with at least one hyperscale cloud platform (AWS, Azure, or GCP)
• Experience working in Agile delivery environments
• U.S. citizenship required
• Active Secret clearance preferred, with ability to obtain and maintain clearance as required

KEY COMPETENCIES:

• Execution-focused architect who balances speed, security, and reliability
• Practices systems thinking and clearly articulates architectural tradeoffs across security, performance, cost, reliability, and delivery speed
• Organized, self-directed operator who manages competing priorities, maintains strong follow-through, and communicates status/risks early in a fast-paced environment
• Effective collaborator able to influence teams and vendors without direct authority
• Clear communicator who translates technical architecture into mission and program language
• Deep understanding of cloud-native architectures, integration patterns (e.g., APIs), and major cloud platforms & managed services
• Communicates effectively with government and contractor stakeholders, including briefing architecture decisions, risks, and recommended paths forward
• Flexible, team-oriented mindset with strong customer service focus
• Demonstrates discretion, professionalism, and sound judgment
• Strong written and verbal communication skills

PREFERRED CERTIFICATIONS (NOT REQUIRED):

• Cloud platform certifications such as AWS Solutions Architect, Azure Solutions Architect, or Google Cloud Professional Architect
• DoD or federal security certifications such as Security+, CISSP, or Certified Cloud Security Professional (CCSP)
• DevSecOps or automation certifications related to Terraform, Kubernetes, or CI/CD platforms
• Architecture or systems engineering certifications such as TOGAF or equivalent

Agile or delivery framework certifications such as SAFe, Scrum, or PMI-ACP
