Job description
T-Rex Solutions is seeking a hands-on Cameo Enterprise Architect to support our DHA Customer, PEO DHMS, through the Workforce 3.0 program within Architecture & Service Excellence (A&SE). The primary responsibility is to build, maintain, and govern enterprise architecture and MBSE models in Cameo Enterprise Architecture / CATIA Magic that provide a traceable source of truth for architecture analysis, integration, modernization, and decision support.
The role also performs enterprise architecture and systems-engineering work across business, application, service, data, infrastructure, integration, technology, and security domains. Support may span ESS Next and shared development/integration/test services, MHS GENESIS / DHMSM, EIDS and data integration, operational medicine / MHS GENESIS-Theater, and other PEO DHMS PMOs as needed. The architect will translate program, engineering, cybersecurity, acquisition, and operational inputs into current-state, transition, and target architectures, risks, roadmaps, and decision products.
Responsibilities:
Build and maintain authoritative enterprise architecture and MBSE models in Cameo Enterprise Architecture / CATIA Magic, applying DoDAF, UAF, SysML, UML, BPMN, or other approved methods appropriate to the architecture problem.
Establish and maintain Cameo modeling conventions, repository/package structures, profiles and stereotypes, naming standards, reusable libraries, templates, traceability methods, validation rules, quality checks, baselines, versioning, and controlled change; support Teamwork Cloud / Cameo collaboration capabilities where used.
Create model-based capability, operational, system, service, data/information, interface, process, sequence, dependency, security, and requirements-traceability views; use diagrams, tables, matrices, queries, and reports to expose gaps, conflicts, dependencies, and incomplete relationships.
Reconcile and migrate architecture information from Visio, PowerPoint, spreadsheets, Systems Architect, requirements repositories, interface documents, and other legacy artifacts into Cameo; generate model-driven outputs for engineering, acquisition, cybersecurity, program, and leadership audiences and coach contributors on model quality and use.
Develop and maintain current-state, transition, and target architectures across enterprise domains, with emphasis on system-of-systems interoperability, cross-PMO dependencies, shared services, and A&SE priorities such as ESS Next and enterprise development/integration/test environments.
Analyze APIs, interfaces, data exchanges, information flows, cloud and infrastructure dependencies, cybersecurity boundaries, DevSecOps pipelines, test environments, and operational constraints; review requirements, use cases, RFP/PWS materials, interface-control documents, technical designs, standards, service catalogs, and test artifacts for architecture impacts and alignment.
Conduct technical research, alternatives analyses, trade studies, impact assessments, and architecture risk analysis; develop recommendations, transition roadmaps, architecture decision records, standards, governance artifacts, and mitigation plans tied to mission and business outcomes.
Facilitate architecture working sessions, model reviews, and technical decision forums; organize incomplete or conflicting inputs into clear architecture options, decisions, actions, and concise briefings for Government, technical, and leadership stakeholders.
Requirements:
Minimum of five years of enterprise architecture, solution/system architecture, systems engineering, MBSE, or digital-engineering experience in a complex technology environment, including recent hands-on experience developing and maintaining models in Cameo Enterprise Architecture / CATIA Magic.
Demonstrated Cameo experience beyond static diagramming, including repository/model structure, traceability, model quality and validation, reusable patterns or libraries, matrices/tables/queries/reports, and collaborative model management; Teamwork Cloud / Cameo Collaborator experience is strongly preferred.
Proficiency with DoDAF 2.02, UAF, SysML, and the development of capability, operational, system, service, data, interface, sequence, process, dependency, and requirements-traceability models. Familiarity with evolving UAF and SysML standards is a plus.
Demonstrated ability to decompose complex systems and model structure, behavior, interfaces, information/data, requirements, dependencies, constraints, and end-to-end mission or business threads at multiple levels of abstraction.
Working knowledge of enterprise and hybrid-cloud environments, APIs and integration, data architecture, cybersecurity/RMF and Zero Trust concepts, DevSecOps/CI-CD, development and test environments, and software/service lifecycle considerations.
Experience translating requirements, acquisition materials, RFPs/PWSs, interface-control documents, technical designs, standards, and test materials into actionable architecture products, technical analyses, and decision support.
U.S. citizenship and ability to obtain and maintain a Common Access Card (CAC) and required access to DHA systems and environments.
Desired Skills:
Bachelor's degree in Systems Engineering, Computer Science, Information Systems, Engineering, or a related field is preferred; equivalent directly relevant experience will be considered. Strong technical writing, modeling, briefing, and facilitation skills are required; INCOSE, OCSMP, TOGAF, or comparable credentials are a plus.
Direct experience supporting DHA, PEO DHMS/DHMS, Workforce 3.0, Architecture & Service Excellence, the Military Health System, or a closely related DoD health-IT environment is strongly preferred. Relevant experience may include ESS/ESS Next, MHS GENESIS/DHMSM, JOMIS, EIDS, operational medicine, FEHRM, or federal health-data interoperability.
Other DoD or federal architecture experience is highly valued. Commercial experience is also relevant when it comes from complex, regulated, multi-stakeholder or system-of-systems environments and the candidate can clearly demonstrate how it transfers to Government interoperability, cybersecurity, acquisition, and governance needs.
