Modeling and Simulation Engineer - ELSYS - Smyrna, GA

Project/Unit Description

GTRI's Systems Engineering Research Division in the Electronic Systems Laboratory (ELSYS) seeks qualified candidates for the position of Modeling and Simulation Engineer for the Methods and Analysis Development Branch (MAD). The MAD Branch provides systems engineering, modeling, and analytical support to empower our stakeholders in navigate their decision‑making processes. MAD emphasizes innovative methods and techniques, specifically through the development and implementation of quantitative and qualitative models, advanced simulations, and state‑of‑the‑art analysis.

The Modeling and Simulation (M&S) Engineer works closely with research, development, and testing teams to combine simulation modeling with data analytics in order to provide recommendations to optimize system designs in support of current and future research, development, and testing efforts. Specifically, the M&S Engineer is responsible for constructing computer simulation models, verifying and validating simulation models, performing simulation experiments to predict system behaviors, providing solutions to project stakeholders, and improving systems and processes.

The M&S Engineer is familiar with important M&S concepts and techniques, constantly keeps abreast of new tool and language developments, and is familiar with a wide range of both open source and proprietary modeling and simulation tools, frameworks, and environments, such as AFSIM, Any Logic, Arena, Extend Sim, Open Foam, Open Modelica, Net Logo, etc. In addition to tools, an M&S Engineer should be aware of many of the core M&S techniques – such as discrete event simulation, continuous simulation, agent‑based modeling, distributed simulation, and conceptual modeling.

At higher levels, the M&S Engineer/Specialist guides and conducts modeling, simulation, and analysis activities which includes eliciting requirements from stakeholders to support the design and implementation of M&S frameworks, computer simulation models, and simulation experiments. Furthermore, the M&S Engineer is responsible for ensuring that models and simulations are designed according to M&S best practices and standards as well as for flexibility to support future modeling needs and enhancements.
