Preferred qualifications * Active DoD Secret clearance. * 5+ years of hands-on MBSE / digital engineering in complex system-of-systems environments. * Master's degree in Systems Engineering, Enterprise Architecture, or a related field. * Direct experience supporting USTRANSCOM, DoD logistics, transportation, supply chain, or ERP modernization programs. * Experience generating technical documentation, reports, and deliverables directly from system architecture models. * Experience architecting solutions that integrate COTS/ERP platforms with custom DoD systems. * Ability to extend MBSE tool capabilities through scripting, APIs, or plugins. * Familiarity with digital twin, digital baseline management, and AI/ML integration within MBSE frameworks. * Experience with cloud-based architectures, DevSecOps pipelines, or zero trust in DoD environments (AWS GovCloud, IL4/IL5). * Knowledge of the DoD acquisition lifecycle, JCIDS, and business process reengineering in enterprise transformation. * Certifications such as OCSMP, INCOSE CSEP/ESEP, TOGAF, SAFe, or AWS/Azure architecture credentials. ## Description Serve as a senior system architect on the JTMS platform, applying CACI's Model-Driven Design and Implementation (MDDI) methodology and Model-Based Systems Engineering (MBSE) practices to the S/4HANA-anchored enterprise architecture. Translate joint transportation business processes and architectural intent into authoritative system models that drive design, integration, and verification across the program's release trains - aligned with DoDI 5000.97 Digital Engineering direction. Key responsibilities * Apply CACI MDDI methodology to capture target business processes, system architecture, requirements, and interfaces in a single authoritative system model (Systems Architecture Model / SAM). * Develop and maintain MBSE artifacts using SysML or equivalent (e.g., Cameo Systems Modeler, Capella, or Rhapsody) covering structure, behavior, requirements, and parametric views of the JTMS platform. * Translate business architecture into S/4HANA configuration intent: data model, integration topology, and process flow across FI/CO/FM, MM, SD, GTS, and Transportation Management modules. * Lead integration architecture across REST/SOAP services, enterprise messaging (Kafka or equivalent), API gateways, and the JTMS canonical data model bridging dozens of legacy DoD logistics interfaces. * Align the architecture to DoDI 5000.97 (Digital Engineering), RMF / NIST 800-53 control families, Zero Trust principles under NIST 800-207, and DoD SRG IL4/IL5 hosting constraints. * Govern architecture decisions and trade studies across the program's Agile Release Trains; lead architectural runway planning, model-driven verification approaches, and architecture review boards. * Mentor functional, integration, and DevSecOps engineers in model-driven design discipline; produce and curate architecture documentation aligned to the program's configuration management standards. ## Related Videos - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [ChatGPT and Java: A Match Made in Heaven or Hell?](https://www.wearedevelopers.com/videos/536-chatgpt-and-java-a-match-made-in-heaven-or-hell) - [Communicate efficiently with Software Architecture Diagrams](https://www.wearedevelopers.com/videos/379-communicate-efficiently-with-software-architecture-diagrams) - [Beyond UML: Making Sense of AI-Generated Code through Visual Architecture](https://www.wearedevelopers.com/videos/2102-beyond-uml-making-sense-of-ai-generated-code-through-visual-architecture) - [Grappling With Clunky Old Software?
