Designs, develops, implements, verifies and tests algorithms to perform guidance, navigation and control of aircraft, spacecraft, launch vehicles and upper stages during powered and coast phases of flight, earth orbit, interplanetary cruise and orbital insertion, as well as during staging events. Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations and control laws to achieve a desired position in space. Control design and analyses processes consist of the development of the control requirements for aircraft, launch vehicles and/or spacecraft.
This person will join a highly skilled team of systems engineering technologists and algorithm developers supporting various contracts and IRADs within Missiles and Fire Control. Modeling & Simulation Engineer tasks include:
• Design and documentation of model and simulation requirements and architecture
• Develop, verify, and validate both complex models and simulations such as missile 6-degree-of-freedom simulations (6-DOF) and effects-based simulations
• Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements
• Perform critical studies, analyses, and test activities
• Support ground and flight test efforts including Hardware-In-The-Loop (HWIL) activities
• Support program reviews and technical interchange meetings with internal leadership and/or external customers.
The candidate must have experience in weapon system and/or sensor modeling, both for the items to be modeled, and the synthetic modeled environments used to stimulate the simulated hardware.
The M&S Engineer must be able to work with subsystem and software engineers to integrate MATLAB models, C++ models, and actual tactical software into the simulations.
The M&S Engineer must be proficient in C++ and MATLAB. The candidate must have good communication skills and must be comfortable working in a collaborative environment.
Post secondary STEM degree with 3+ years of relevant experience.
• A Interim DOD Clearance is needed to start this position, therefore you must be a US Citizen.
