Naval MBSE Systems Modeler | SysML & Parametric Modeling

NSS; Washington (District of Columbia); On-site; USD 90,000 - 130,000; Full time

Job summary

NSS seeks a Systems Modeler to develop, build and maintain MBSE products supporting a Navy customer in Washington, DC. Onsite full-time with a Secret clearance preferred or sponsorable. The role emphasizes parametric SysML modeling, dynamic behavior, and traceability of requirements and designs.

The candidate will leverage Cameo Systems Modeler, MATLAB/Simulink, and Modelica to build executable models and support engineering analyses and trade studies for decision-makers.

Qualifications

• Bachelor's degree required.
• At least 3 years in systems engineering, MBSE, or systems modeling.
• Hands-on SysML parametric modeling experience.
• Experience with dynamic system behavior and simulation-based methods.

Responsibilities

• Develop and maintain SysML models representing system structure, behavior, and interfaces using Cameo or MBSE tools.
• Build parametric models and constraint blocks to capture relationships and design trade-offs.
• Model dynamic system behavior using state machines, activity diagrams, sequence diagrams, and simulations.
• Represent time-dependent and state-driven behavior of complex systems including control loops and mode transitions.
• Support trade studies and engineering analyses via parametric and behavioral models.
• Integrate SysML models with MATLAB/Simulink or Modelica to validate dynamics.
• Maintain traceability between requirements, functions, interfaces, and model elements.
• Support architecture products including mission threads, use cases, activity diagrams, and requirements architectures.
• Apply modeling conventions and CM practices established by lead architect or model owner.
• Participate in technical reviews, architecture working groups, and stakeholder meetings to present models.
• Document modeling assumptions, methods, and results for reports and briefings.
