Sr. GNC Engineer / Modeling & Simulation

Mavensoft Technologies. • Chandler, AZ

1d • Onsite

About The Position

Lead the development and evaluation of guidance, navigation, and control (GNC) systems for advanced aerospace applications, including aircraft, spacecraft, missiles, and launch vehicles. Apply mathematical modeling, control theory, and algorithm development to achieve precise navigation and control performance, and own key analysis and design tasks. Work includes architecting and maintaining six degrees of freedom (6 DOF) simulations, defining performance metrics, designing and implementing solutions, and integrating hardware and software components to support system reliability and mission success. Mentor early-career engineers, provide technical direction on GNC approaches, and collaborate with cross-functional teams on integration, test, and analysis activities.

This is a 12-month W2 contract role performed onsite in Chandler, Arizona. The position is contingent upon obtaining and maintaining required program access within a reasonable period, as determined by the company. Applicants must be U.S. citizens and hold a current, active Secret security clearance.

Requirements

• Bachelor’s degree and 8 years of professional experience, or a master’s degree and 6 years, or a PhD and 4 years, in aerospace engineering, mechanical engineering, electrical engineering, or a related engineering discipline.
• Existing U.S. Government Secret-level security clearance.
• Demonstrated experience with guidance, navigation, and/or control concepts, algorithms, or analysis for aerospace or missile systems.
• Experience leading or significantly contributing to development, modeling, simulation, test, integration, or analysis activities for aerospace or autonomous systems.
• Proficiency in one or more of C++, Python, MATLAB/Simulink, or similar technical software tools, with development in a Linux environment.
• U.S. citizenship.

Nice To Haves
