Lead Modeling and Simulation Engineer

About the Sensors Division

The Sensors Division at STR develops advanced sensor technologies across airborne and surface-based radar, electronic warfare, underwater acoustics, hyperspectral imaging, and EO/IR systems. Work spans from component-level technology development through integrated prototype systems. Core capabilities include RF hardware, signal processing, tracking and fusion, machine learning, and real-time embedded implementation.

As a Lead Modeling and Simulation (M&S) Engineer, you will lead teams working a portfolio of projects focused on advanced modelling and simulation (M&S) capabilities, including RF system development, capability implementation, and integration of emerging capabilities into M&S environments. A particular growth area is the development of real-time M&S capabilities paired with hardware-in-the-loop simulation in support of operational test and evaluation efforts.

This position requires skills in performing and leading multi-disciplinary teams designing and analyzing complex systems and representing them in simulation. Strong technical, interpersonal, communication, and technical leadership skills are needed.

• Lead small, multi-disciplinary teams in the design, development, integration, and testing of physics-based modeling and simulation tools for RF sensor systems
• Architect and implement effects-based simulations to evaluate system performance in operationally relevant scenarios
• Guide implementation of event-based and agent-based models, including translating verified algorithms into performant C/C++ implementations
• Maintain and extend existing M&S frameworks to incorporate new sensors, platforms, and processing approaches
• Develop and apply advanced domain knowledge in airborne radar systems, with working familiarity across adjacent RF domains
• Work with RF sensor engineering teams to develop system models, conduct performance analyses, and support design trade studies
• Support development of hardware-in-the-loop and real-time simulation capabilities aligned with test and evaluation needs
• Serve as a primary technical interface with sponsor organizations on assigned projects
• Collaborate with internal teams across Sensors Division and with external partners to ensure integrated system solutions
• Translate customer operational needs into well-scoped technical approaches and simulation implementations.

• Ability to obtain a secret security clearance, for which U.S. citizenship is needed by U.S. government
• Bachelor’s degree and at least 7 years of applicable experience;
  Master’s degree and at least 5 years of applicable experience; or PhD and at least 2 years of applicable experience. Equivalent experience will be considered.
• Demonstrated experience leading small technical teams or project tasking on advanced R&D programs (e.g., DARPA, AFRL, NAVAIR, ONR)
• Experience designing, implementing, and maintaining modeling and simulation codebases for complex systems
• Experience integrating new capabilities into existing M&S environments
• Strong communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences
• Proficiency with tools such as C/C++, Python, MATLAB, Simulink, and related analysis environments

• Active security clearance
• Ph.D. in Physics, Applied Mathematics, Electrical Engineering, or related field
• Experience with RF systems beyond radar (e.g., EW or communications)
• Experience supporting test and evaluation, including operationally focused analysis
• Exposure to advanced computing architectures, real-time systems, or data-intensive simulation environments
