Job description

Description

We are seeking a Systems Engineer - Modeler to lead MBSE driven architecture, requirements, and interface modeling for CMCC. You will develop and maintain system models (ensure endtoend traceability, and support SIPaligned onboarding and integration, working closely with the Chief Engineer, System Architect, Integrator, Release Manager, and Government stakeholders to keep the technical baseline accurate, testable, and mission ready. Job Responsibilities:

  • Apply systems engineering best practices across the lifecycle: concept, requirements, design, integration, V&V, deployment, and disposal.
  • Develop and maintain MBSE models (SysML; DoDAF/UPDM/UAF) in Cameo Systems Modeler / Teamwork Cloud to capture architecture, behavior, data flows, and interfaces.
  • Lead requirements definition/decomposition; maintain bidirectional traceability across requirements, architecture, test artifacts, and Agile backlog items.
  • Conduct trade studies, AoAs, and risk assessments; define/manage system interfaces to ensure interoperability across CMCC components and externals.
  • Support SIP aligned capability onboarding, CCB decisions, and model updates for Factory, I&T, Experimental, and Operational environments.
  • Collaborate with software, hardware, cyber, and test teams to drive cohesive system design; prepare and present model based documentation and briefings.
  • Manage model repositories, versioning, and configuration in TWC; generate model artifacts (OVs, UAF views, sequence diagrams, operational threads).
  • Contribute to Agile/ART activities (PI Planning, demos, retrospectives), highlight dependencies, and recommend model driven improvements to flow efficiency and velocity.
  • Partner with program management to align technical solutions with schedule/budget; identify process improvements that elevate MBSE discipline across the program.
