Senior Materials Engineer (Metals, Forming & Castings

We are seeking a Senior Materials Engineer to lead failure analysis, metallurgical investigation, and root-cause corrective action for our Materials & Failure Analysis team. This is a senior, independent contributor role for someone who owns investigations end-to-end; from initial part triage through mechanical testing, metallurgical analysis, and cross-functional resolution with Design, Manufacturing, and Supplier Quality. The ideal candidate has deep expertise across metals and metal manufacturing processes;

forming, stamping, and castings, and is comfortable authoring the specifications that govern them, working at the microscope, running mechanical tests in the lab, and presenting findings to program leadership.

• Lead failure investigations for metallic components across development, production, and field releases; execute mechanical testing and metallurgical characterization (SEM/EDS, metallography, fractography) to determine root cause and mitigations.

• Advise Design, Manufacturing, and Quality teams on metal selection, process capability, and process-induced failure modes for forming, stamping, and casting operations (DFMEA/PFMEA).

• Draft and maintain material and process specifications, quality acceptance criteria, and ASTM/ISO/SAE test procedures.

• Support supplier material and process qualification for formed, stamped, and cast metal components, including review of PPAP submissions and material certifications.

• Manage lab test plans, equipment calibration, SOPs, and safety standards while directing external vendor labs and mentoring junior engineers.

• Bachelor’s or Master’s degree in Materials Science & Engineering, Metallurgical Engineering, Mechanical Engineering, or a related field.

• 8+ years of experience in materials engineering, failure analysis, or metallurgical engineering, ideally in automotive, aerospace, or heavy equipment.

• Deep, hands-on expertise with metals across forming/stamping and casting processes, and their common failure modes
  
  Deep, hands-on expertise with metals across forming/stamping and casting processes, and their common failure modes as well as writing and reviewing processes.

• Strong experience with mechanical testing (Instron/UTM systems) and failure analysis techniques (fractography, SEM/EDS, metallography, hardness testing).

• Demonstrated track record independently leading root cause investigations and driving corrective actions to closure with cross-functional teams.

• Working knowledge of ASTM/ISO/SAE test standards and experience developing test specifications.

• Excellent written and verbal communication skills, with the ability to translate technical findings for non-materials audiences and leadership.

• Experience mentoring or directing the work of junior engineers or technicians.

• Experience with polymers, composites, adhesives/bonded joints, or coatings failure analysis.

• Familiarity with forming/stamping simulation tools (e.g., Auto Form, LS-DYNA), casting simulation, or DFMEA/PFMEA processes.

• Experience with supplier quality engineering, PPAP, or material certification review.

• Prior experience in high-volume automotive manufacturing or a vehicle development environment.

• Advanced degree (MS/PhD) in Materials Science or Metallurgy.
