These qualifications are crucial for accurately representing complex systems, translating requirements into effective models, and collaborating with multidisciplinary teams to achieve project goals.

What does a modeling simulation engineer do?

A Modeling Simulation Engineer develops virtual models and simulations to analyze complex systems and processes. They use mathematical models, computer simulations, and data analysis to predict system performance and optimize designs before physical implementation. These engineers typically work in industries like aerospace, defense, automotive, and healthcare to improve efficiency, safety, and decision-making. Their role often involves coding, algorithm development, and working with simulation software to test real-world scenarios in a virtual environment.

What are the typical responsibilities and project stages for a modeling simulation engineer?

Modeling Simulation Engineers are responsible for developing mathematical models, running simulations, analyzing results, and providing recommendations to improve system performance or design. Projects often begin with understanding client or stakeholder requirements, followed by designing models based on those needs and iteratively refining them as data is collected. Engineers work closely with design, hardware, and software teams to validate models and ensure alignment with real-world performance. Collaborating with colleagues and presenting findings to both technical and non-technical audiences are routine aspects of the job, making cross-functional communication vital for project success.

Key Responsibilities
Modeling & Simulation Engineering
  • Develop, integrate, and validate models and simulations supporting various weapons systems
  • Extensive testing of the simulations themselves to verify their suitability for weapon systems requirements verification.
  • Assist in development of weapon systems requirements verifications, develop scenarios to verify those requirements, analyzing the results using MATLAB or python tools, and digging into the C++ source code of the simulation to track down reasons for apparent requirements failures.
  • Ensure traceability from system requirements to models, test cases, and analysis results.

Technical Leadership & Integration
  • Leadership abilities and experience to be able to backfill into Product Owner and/or Scrum Master roles should the situation require it
  • Interface with customers to clarify requirements, provide status, and positively represent both the team and NG as a company
