Modeling and Simulation Engineer

We're seeking an experienced Modeling and Simulation Engineer to join a dynamic team.


Responsibilities:

• Develop, modify, and validate TMAP models to represent mechanical, aerospace, and space-related systems in support of intelligence analysis.
• Use MATLAB/Simulink (especially Simulink ) to develop and integrate component- and system-level models and to support analysis workflows.
• Integrate TMAP and MATLAB/Simulink models with broader modeling & simulation environments , including AFSIM and other tools when appropriate.
• Collaborate with a multi-disciplinary team of engineers, analysts, and government/DoD personnel to:
  • Understand system behavior and mission context
  • Translate analysis requirements into model architectures
  • Quantify and communicate uncertainty, assumptions, and limitations.
• Apply coding skills (e.g., Python , C++ , or similar languages) to automate workflows, process data, and support model execution.
• Contribute to technical documentation and Client-based reports that describe modeling approaches, input assumptions, and analytical findings.
• Work within an Agile development environment , using tools such as Jira to manage tasks and collaborate effectively.
• Communicate technical information and results clearly to both technical and non-technical audiences.

Basic Qualifications:

• Bachelor of Science degree in Mechanical Engineering , Aerospace Engineering , or similar engineering discipline with 2+ years of relevant experience; or a Master of Science degree with 0 years of relevant experience.
  • Candidates with Computer Science or Software Engineering degrees will also be considered, provided they demonstrate strong interest and ability to learn the required mechanical/aerospace domain context .
• U.S. Citizenship with an active TS/SCI security clearance (and ability to maintain it).
• Experience using MATLAB , with strong proficiency in Simulink .
• Hands-on coding experience in one or more languages (e.g., Python , C++ , MATLAB).
• Demonstrated familiarity with modeling & simulation of mechanical or aerospace systems.
• Ability to work both independently and collaboratively within a technical team.
• Strong written and verbal communication skills.

Preferred Qualifications

• Prior experience using or modifying TMAP models
• Experience with AFSIM or other modeling & simulation platforms (e.g., STK, NGTS, ITASE).
• Experience working on Agile development teams , including use of Jira .
• Experience interpreting and working with Client-based data and reports to inform models.
• Prior IC/domain experience (working with NASIC/NSIC or similar organizations).
• Experience documenting complex models and analysis results for technical and non-technical stakeholders.
• Familiarity with Model-Based Systems Engineering (MBSE) concepts, SysML, or Cameo.
