Job 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 (Cameo/TWC), 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.

This role is hybrid remote located in Chantilly, VA, Beale AFB, CA or Colorado Springs, CO.

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.


Qualifications

Required Qualifications:
  • TS/SCI and US citizenship.
  • Bachelor's and 14+ years of experience; OR Master's and 12+ years; OR PhD/JD and 9+ years.

  • 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.

Desired 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.
