Dec 11, 2025
We are seeking a highly motivated Modeling and Simulation (M&S) Engineer to join our team at either Edwards Air Force Base, CA or Nellis AFB, NV. This critical role supports the Joint Simulation Environment (JSE), which is a high-fidelity virtual environment used for man in the loop mission simulation of cutting-edge DoW aircraft. The JSE is used for high-end pilot training and test in support of acquisition and operation for a variety of new and existing aircraft platforms. This position is very dynamic and will draw on a breadth of skills. Lessons learned with JSE have direct applicability to the warfighter, so maintaining fidelity to the real world is paramount. As such, the well-positioned candidate will have experience with development, test or training for real tactical or strategic aircraft as foundation. Prior experience with JSE architecture, software or operations is highly desirable. Other desirable technical skill sets include, but are not limited to, familiarity with systems engineering, validation and verification methodologies, scientific scripting languages (e.g. Python, MatLab/Simulink, C++), USAF test planning and report writing, information system administration, engineering analyses of mission systems, flight test conduct and range operations, Agile applications (e.g. JIRA, CONFLUENCE) and processes, data analytics, and emerging technologies. Roles & Responsibilities Based on Experience: * V&V: Contribute to fidelity and realism of the virtual environment, aircraft platforms and mission systems within the JSE. Participate in the development and execution of comprehensive V&V test programs, ensuring the delivered simulation capability meets user needs. * Test Preparation & Execution: Write test plans, generating detailed test cards/test procedures which trace to requirements and provide necessary data. Participate in simulation planning and scenario development. Participate in test execution as a discipline engineer, test conductor or JSE operator. * Data Analysis & Reporting: Condition and analyze raw simulation data using tools developed in Python and MATLAB. Collect, organize, and document data and results required to meet test point objectives. Define and assemble data packages for delivery to customers. Participate in troubleshooting simulation anomalies, contributing to determination of root causes. Write data reports and test reports for presentation to customers for their specific use cases. * Technical Competency & Collaboration: Rapidly assimilate system-under-test and JSE system knowledge. Participate in system requirement reviews, preliminary/critical design reviews, other programmatic reviews and stakeholder meetings. Coordinate across multiple teams and organizations.
