Principal MBSE Systems Engineer

About the role

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 end-to-end traceability, and support SIP-aligned onboarding and integration. You will work closely with the Chief Engineer, System Architect, Integrator, Release Manager, and Government stakeholders to keep the technical baseline accurate, testable, and mission-ready.

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.

Requirements

• TS/SCI clearance with polygraph and US citizenship.
• Bachelor’s degree and 10+ years of experience; OR Master’s degree and 8+ years; OR PhD/JD and 6+ years.
• 10+ years of systems engineering on complex defense/space/C3BM programs, including 5+ years hands-on MBSE with Cameo (or Sparx EA/Rhapsody).
• Proficiency in SysML and architecture frameworks (DoDAF/UPDM/UAF); experience with requirements tools (e.g., DOORS, JAMA) and Atlassian (Jira/Confluence).
• Proven ability to perform trade studies, interface control, risk analysis, and to translate model outputs into actionable technical direction.
• Strong communication skills for technical writing, model curation, and stakeholder briefings; collaborative working style across multidisciplinary teams.

Qualifications

• Familiarity with SIP/CCB workflows, external interface modeling (e.g., UCI), and automated model validation/scripting.
• INCOSE ASEP/CSEP certification; SAFe or Scrum credentials.
• Experience with Git-based version control; exposure to DevSecOps-aligned digital engineering toolchains.
