Preferred qualifications * INCOSE CSEP / ESEP certification or equivalent. * TOGAF or DoDAF working knowledge; prior DoDAF view production for an ACAT-class system. * Experience designing model-driven verification, test-as-you-build, and automated architecture compliance checks. * Prior USTRANSCOM, JDDE, or joint logistics modernization architecture experience. ## 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., * 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) - [Goodbye Microservices, Hello Self-Contained Systems](https://www.wearedevelopers.com/videos/100009-goodbye-microservices-hello-self-contained-systems) - [Grappling With Clunky Old Software?
