Sr. Principal High Temperature Materials Engineer

About the Team

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Materials and Process Engineering Department, within Hardware Engineering, is seeking a Senior Principal High Temperature Materials Engineer to join our Advanced Materials Section in Tucson, Arizona. This role is integral to our mission of incorporating high-temperature materials into deliverable products and assessing system performance.

About the Role

As a Senior Principal High Temperature Materials Engineer, you will serve as a technical leader and subject matter expert, defining the strategic direction for material decisions across multiple programs. You will drive the execution of these strategies while managing and coordinating a wide variety of simultaneous tasks within strict schedule constraints.

You will work within integrated product teams to solve the most challenging high-temperature materials issues. Your day-to-day involves defining design verification test requirements to quantify key performance characteristics and environmental interaction effects. You will provide independently determined solutions to create high-fidelity simulations and models for missile system design, performance assessment, and flight test support. Additionally, you will mentor engineers, providing shoulder-to-shoulder empirical experience and guiding them through complex technical landscapes.

This position requires a deep advocacy for technical integrity in disciplines such as high-temperature metals, composites, coatings, Ceramic Matrix Composites (CMC), and refractory metals. You will be responsible for delivering test documentation, data analysis, anomaly resolution, and presenting results to both internal and external customers.
