You will provide mentorship and shoulder-to-shoulder empirical experience for engineers.
You will work independently or through leadership of teams to solve the hardest high temperature materials challenges.
You will be a strong advocate for technical integrity of and have advanced experience/knowledge in high temperature material disciplines such as:
High temperature metals, composites, and coatings, and their fabrication processes.
High temperature materials spanning the technologies of Ceramic Matrix Composites (CMC), Carbon/Carbon (C/C), SiC (Si/C) ceramics, RF and EOIR apertures, refractory metals, ablative coatings, and high temperature alloys.
Environmental barrier and oxidation resistant coatings, component integration and materials modeling.
Heat management and rapid heat transfer techniques.
Related manufacturing technologies, integration, and environmental testing.
High temperature test methods such as arc-jet.
Experience with Root Cause / Corrective Action resolution.
