System Architect — MDDI / MBSE

Serve as asenior system architect on the JTMS platform, applying CACI’s Model-DrivenDesign and Implementation (MDDI) methodology and Model-Based SystemsEngineering (MBSE) practices to the S/4HANA-anchored enterprise architecture.Translate joint transportation business processes and architectural intent intoauthoritative system models that drive design, integration, and verificationacross the program’s release trains — aligned with DoDI 5000.97 DigitalEngineering direction.

Key responsibilities

Apply CACI MDDI methodology to capture target businessprocesses, system architecture, requirements, and interfaces in a singleauthoritative system model (Systems Architecture Model / SAM).

Develop and maintain MBSE artifacts using SysML orequivalent (e.g., Cameo Systems Modeler, Capella, or Rhapsody) coveringstructure, behavior, requirements, and parametric views of the JTMS platform.

Translate business architecture into S/4HANAconfiguration intent: data model, integration topology, and process flow acrossFI/CO/FM, MM, SD, GTS, and Transportation Management modules.

Lead integration architecture across REST/SOAPservices, enterprise messaging (Kafka or equivalent), API gateways, and theJTMS canonical data model bridging dozens of legacy DoD logistics interfaces.

Align the architecture to DoDI 5000.97 (DigitalEngineering), RMF / NIST 800-53 control families, Zero Trust principles underNIST 800-207, and DoD SRG IL4/IL5 hosting constraints.

Govern architecture decisions and trade studies acrossthe program’s Agile Release Trains; lead architectural runway planning,model-driven verification approaches, and architecture review boards.

Mentor functional, integration, and DevSecOps engineersin model-driven design discipline; produce and curate architecturedocumentation aligned to the program’s configuration management standards.

Required qualifications

​

U.S. citizenship with an active DoD Secret clearance orthe ability to obtain one (we will sponsor eligible candidates).

7+ years designing enterprise, system, or solutionarchitectures for large-scale IT programs in DoD or comparableregulated/enterprise environments.

Demonstrated systems-engineering capability: youcan decompose a complex system and model its structure, behavior, interfaces,data, and end-to-end mission/business threads with full traceability —independent of any single tool.

Working proficiency with a SysML/UML modeling approachin a recognized tool (e.g., Cameo Systems Modeler / MagicDraw, Sparx EA,Rhapsody, GENESYS, or similar), plus familiarity with an architectureframework such as DoDAF or UAF.

Strong communication skills, including technicalbriefings and architecture documentation for executive and senior militaryaudiences.

Aptitude and motivation to deepen MBSE anddigital-engineering skills, with support from our digital-engineering communityof practice.

Bachelor’s degree in Systems Engineering, ComputerScience, Engineering, Information Systems, or a related technical field — orequivalent professional experience.

Preferred qualifications

Active DoD Secret clearance.

5+ years of hands-on MBSE / digital engineering incomplex system-of-systems environments.

Master’s degree in Systems Engineering, EnterpriseArchitecture, 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 integrateCOTS/ERP platforms with custom DoD systems.

Ability to extend MBSE tool capabilities throughscripting, APIs, or plugins.

Familiarity with digital twin, digital baselinemanagement, and AI/ML integration within MBSE frameworks.

Experience with cloud-based architectures, DevSecOpspipelines, or zero trust in DoD environments (AWS GovCloud, IL4/IL5).

Knowledge of the DoD acquisition lifecycle, JCIDS, andbusiness process reengineering in enterprise transformation.

Certifications such as OCSMP, INCOSE CSEP/ESEP, TOGAF,SAFe, or AWS/Azure architecture credentials.
