Experience
Materials and Process Engineer
Jan 2020 — Present · Seattle, WA, US
Lead materials and processes engineer supporting valves and mechanisms on multiple engine programs; including reviewing engineering drawings, dispositioning non-conformances, working with designers and analysts to drive design changes.• Supported engineering systems utilizing stainless steels, Ni super-alloys, titaniums, aluminums, coppers, and non-metallics (limited to sealing and wear applications).• Lead the team creating and maintaining the companywide material property database.• Performed failure analyses and foreign object debris characterization for various systems; including turbomachinery, combustion devices, valves and mechanisms for multiple engine programs.• Characterized environmentally assisted damage tolerance properties of various Ni based alloys to drive maximum operational conditions.• Managed and designed over $1 mil in material test campaigns for both material qualification and allowables development.• Established tools and standard procedures for generating and handling new and old material property data for various material behaviors; including static (tensile and physical), dynamic (fatigue, fracture, fatigue crack growth, creep), thermal, and electrical properties. Improving processing time and reducing testing costs.• Primary engineer for fatigue crack growth behavior applied to both material qualification and component analysis.• Reviewed qualification documentation of human rated suborbital, orbital class first and second stage engines.• Evaluated gaseous and liquid oxygen systems and authored oxygen compatibility assessments to document risks and ignition mechanisms of metallic and non-metallic materials used.• Evaluated gaseous and liquid hydrogen systems to determine susceptibility to hydrogen embrittlement and deep cryogenic compatibility of the materials used.• Mentored interns, new grads, and early career engineers on internal processes and technical topics; primarily in fatigue, fracture, and fatigue crack growth.
