Guide materials selection and processing for high-performance engine components, including rotating and reciprocating parts
Evaluate and implement surface treatments, coatings (PVD/CVD, HVOF, plating), and thermal barrier solutions
Lead tribological analysis and make recommendations for improving wear resistance in lubricated engine environments
Oversee and maintain the metallurgy lab, including heat-treat ovens, hardness testers, microscopes, and wear testing equipment
Support engine test programs through inspection, failure analysis, and post-test component evaluation
Collaborate with internal teams and external specialists (e.g., gear, seal, and coating vendors) to solve material challenges
Act as the primary technical contact for raw material and coating suppliers
Create and enforce standardized procedures for material selection, treatment, and documentation
Present findings, material analyses, and recommendations to technical and executive teams
Proactively contribute to R&D efforts by inventing and evaluating new material solutions that enhance performance, manufacturability, or cost-effectiveness
Maintain an adaptive, solution-focused mindset to tackle the unique challenges of novel engine development
Required Qualifications:
MS or higher in Materials Science, Metallurgical Engineering, or related field
5+ years of professional experience in materials selection, processing, and testing
Expertise with metallic materials such as aluminum, steel, magnesium, titanium, and MMCs
Strong knowledge of tribology, fatigue analysis, and failure mechanisms relevant to mechanical systems and engines
Familiarity with thermal barriers, welding, and joining technologies for dissimilar metals
Experience with both traditional and modern manufacturing methods for precision metal components
Demonstrated ability to work independently and lead technical efforts across disciplines
Hands-on experience with post-service failure analysis and report writing
Preferred Skills:
Experience with engine development or rotating machinery
Familiarity with CAD tools (e.g., SolidWorks) and mechanical simulation tools (ANSYS, MATLAB)
Experience in R&D or prototype development environments
Strong communication skills, including technical writing and presenting findings to diverse teams
Benefits:
Flexible PTO to encourage work-life balance and personal well-being
Comprehensive healthcare coverage: medical, dental, and vision plans
Equity participation: RSUs for all permanent employees
401(k) with match: 100% up to 3%, plus 50% match for 3–5% range
