MTSI is seeking a Model-Based Systems Engineer (MBSE) with specialized Mission Engineering experience to join our team.

The ideal candidate is someone who can bridge the gap between abstract military missions and rigorous digital architectures by translating operational Concepts of Operations (CONOPS) into executable System-of-Systems (SoS) models and facilitate integration of those digital models into mission level simulation or analysis tools.

Duties:

  • Lead multi-disciplinary working group, brief military stakeholders on architecture trade studies, author technical content, and assign technical duties as needed.
  • Translate warfighter CONOPS and mission scenarios into executable behavioral models and digital threads
  • Build and maintain enterprise and system architecture models using SysML, UAF, or DoDAF in Cameo Systems Modeler
  • Capture operational concepts, functional architectures, and logical/physical interfaces
  • Identify/Track Measures of Effectiveness (MOEs) and Technical Performance Measures (TPMs) to evaluate mission success
  • Integrate descriptive MBSE system models with mission-level modeling & simulation (M&S) tools like AFSIM, STK, or MATLAB/Simulink to quantify system-of-systems performance
  • Establish end-to-end digital traceability from high-level mission capabilities and requirements down to subsystem components and verification/validation (V&V) procedures

Education & Experience

  • Bachelor’s Degree in Systems Engineering, Operations Research, or a highly related STEM discipline
  • Minimum of 7 years of progressive experience with at least 4 years directly focused on MBSE application using SysML and executing DoD/DoW-style Mission Engineering or System-of-Systems analysis
  • Systems Modeling Rigor: Advanced, hands-on experience utilizing Cameo Systems Modeler or MagicDraw
  • Deep understanding of SysML diagrams
  • Proven mastery of Unified Architecture Framework (UAF), DoDAF 2.02, or similar enterprise frameworks
  • Familiarity with integrating MBSE environments with modeling, simulation, and analysis (MS&A) suites such as AFSIM (Advanced Framework for Simulation, Integration, and Modeling), Ansys STK (Systems Tool Kit), or MATLAB/Simulink
  • Expertise establishing digital threads using requirements databases like DOORS or DOORS Next Gen linked directly to the system model

Desired Qualifications

  • OMG Certified Systems Modeling Professional (OCSMP) Certification (Model Builder - Intermediate or Advanced level).
  • Experience with model-based scripting and automation using Python, JavaScript, Jira, Confluence, Apache Groovy, or Apache Velocity Template Language (VTL) inside Cameo to autogenerate interface control documents (ICDs)
  • Prior experience supporting Joint All-Domain Command and Control (JADC2) initiatives, space systems, or integrated air and missile defense (IAMD) mission areas

Security Requirements

  • Must be a US Citizen.
  • Active Secret clearance is required at start
