<p>Candidates should have at least three years of proven experience in GNC system analysis pertaining to algorithm development; inertial and satellite navigation technology; sensor fusion and integration techniques; and classical and modern controls. Candidates should have knowledge of guidance and navigation techniques of various aerospace vehicles and an understanding of classical dynamics. Candidates should have demonstrated skill sets in modeling, simulation, and analysis software such as MATLAB/Simulink and experience in at least one or more general purpose programming languages such as C, C++, and Python. The candidate must be a motivated self-starter who is able to work both independently and in a collaborative team environment, often with minimal guidance. The candidate must have sufficient communication skills in conveying complex technical issues and in providing comprehensive written, oral and/or digital products. The candidate must also have sufficient technical writing and presentation development skills. The candidate must have good analytic skills and the ability to apply them in a multi-tasking environment where more than one project may require the candidate's participation at any given time (typically one primary project and one or two ancillary projects). 3 to 8 years of experience with development of 6DOF aerospace models. Demonstrated conscientious and collaborative work habits to effectively augment our customers GNC team. A master's degree in either electrical or aerospace engineering with an emphasis on either control theory, modeling & simulation, or mathematical optimization of dynamic systems. Specific experience with inertial instruments, inertial measurement units, and global satellite navigation systems and their use in navigation and guidance systems. Specific experience in performing guidance and control error analysis. Demonstrated experience with software developmental practices including version control (e.g. via git), test driven software development, and object-oriented programming. Bachelor's degree in mechanical engineering, aerospace engineering or a related field. Applicants must have at least an active SECRET clearance. Applicants should have an active TOP SECRET clearance with Sensitive Compartmentalized Information (SCI) eligibility. U.S. Citizenship is required for most positions.</p>
