Job Description and Key Tasks:

The Senior Systems Engineer II will work across multiple disciplines (e.g. Guidance, Navigation, and Control, signal processing, mechanical design) to design and develop multiple fidelities of simulation models which represent the components of a system. This includes showcasing the ability to read, debug, edit and create computer programming code to enhance simulation models, creating and executing unit tests on the models to verify functionality, documenting the design and test results, and integrating with other component models in a complex system simulation environment. This may also include development of interfaces to support Computer and Hardware-in-the-Loop capabilities within the simulation framework.

The Senior Systems Engineer II will execute simulations in a high-performance computing environment, which can include the use of Graphics Processing Units (GPUs), to support missile system design/trade studies, performance assessment, and system test. The Senior/Principal Simulation Engineer will develop analysis of the data for the specific task as well as provide detailed insight and understanding of the system performance, recognizing and troubleshooting any anomalies observed in the simulation results.

The Senior Systems Engineer II will assist in the preparation of detailed simulation plans, which may include developing task objectives, determining expected output, budget requirements and developing the Integrated Master Schedule (IMS). The Senior/Principal Simulation Engineer may interact with government counterparts as an authority on simulation products and may work at the customer site to assist with execution of the simulation and analyze the results.

Please note:

We are not seeking engineers with an AutoCAD or 3-D modeling background or network modeling from an IT perspective.
