• Experience with process development, as pertains to thermal analysis methods, testing methods, or model correlation.
• Knowledge of environmental requirements, engineering, thermal vacuum/ambient pressure testing, and hands-on engineering project experience, including use of data acquisition systems.
• Strong knowledge of thermal design management, surface treatments, and insulation material (MLI) used in aerospace and space applications.
• Must possess an understanding of the basic principles of radiation and conduction and convection heat transfer in conjunction with space environment heating effects and parameters associated with spaceflight applications.
• Deep understanding of orbital mechanics and thermal design considerations with respect to launch, MEO, LEO, GEO, and other orbits.
• Experience with CAD software such as NX, Fibersim, SolidWorks, CATIA, etc.
• Proficiency with computational scripting languages (MATLAB, Python, Mathematica, etc.).
• Must have experience leading teams and mentoring entry-level engineers.
• Detail-oriented and organized, with the ability to manage multiple priorities in a fast-paced environment with a strong desire to be a leader/key contributor on a small team.
