Along with our customers and the communities we work and live in, we are building a better world for tomorrow.

We are seeking a highly motivated Materials Engineer to support the development, qualification, and application of advanced high-temperature metallic materials for industrial gas turbine and energy applications. The successful candidate will provide technical leadership in the areas of nickel-based superalloys, cobalt-based superalloys, high-temperature steels, and related manufacturing processes
. This role involves alloy development, materials characterization, failure analysis, supplier qualification, and process development to improve component durability, reliability, and performance in demanding environments. The engineer will work closely with design, manufacturing, quality, supply chain, and external research partners to solve complex materials challenges.
