The Role

In this role you'll provide technical leadership in materials selection, qualification, and application for GM Defense integrated vehicles. Ensure compliance to GM material specifications (e.g., GMW, ASTM) and support robust, cost-effective designs that meet performance, durability, and corrosion requirements in collaboration with cross-functional teams (Design, Release, Manufacturing, Validation, Purchasing, Suppliers).  This role will also lead materials selection and qualification for defense and emerging space-related applications, ensuring compliance with applicable DoD, MIL, and aerospace/space material standards while balancing performance, survivability, weight, and cost.

What You'll Do

• Coach and lead suppliers to timely execution of program work with perfection.
• Resolve highly sophisticated technical issues and conduct advanced research.
• Recommend alterations to development and design to improve quality of products and/or procedures.
• Own materials engineering decisions for assigned components/systems, including definition and maintenance of material specifications and drawings.
• Evaluate and approve alternate materials and coatings (e.g., metallics, polymers/composites, surface treatments) to meet performance, cost, and timing targets.
• Lead materials-related failure analysis, root cause investigation, and corrective actions for field, plant, and test issues.
• Support DREs and Design with DFMEA, DVP&R, and design reviews focusing on material risks, manufacturability, and corrosion/durability.
• Partner with suppliers on material qualification, PPAP, and ongoing quality/performance monitoring.
• Interpret and apply GMW/ASTM/ISO material and test standards; ensure documentation and data traceability.
• Provide guidance on corrosion prevention, coatings, and compatibility for multi-material joints and fastened assemblies.
• Document and communicate technical recommendations, test results, and lessons learned to stakeholders.
• Evaluate and qualify materials for extreme defense and space environments (e.g., high-g and blast loading, thermal cycling, vibration, vacuum/outgassing, radiation, and atomic oxygen).
• Interpret and apply DoD, MIL, and aerospace/space materials standards (e.g., MIL-STD/MIL-PRF, NASA material and process specifications) and ensure traceable compliance in material and process documentation.
• Support design and analysis of armor, survivability, thermal protection, and signature management solutions (e.g., ballistic/blast-resistant materials, thermal barrier coatings, low-observable coatings) for GM Defense platforms.
• Develop and execute materials qualification and test plans in collaboration with government customers, test facilities, and suppliers, including ground- or flight-representative test configurations where applicable.
• Partner with suppliers to mature advanced materials and processes (e.g., high-temperature alloys, ceramic and composite systems, additive manufacturing materials, ablatives/thermal protection systems) from prototype through production readiness for defense and space-relevant programs.

Your Skills & Abilities (Required Qualifications)

• Bachelor’s degree in Materials Science, Engineering, Metallurgical Engineering, Mechanical Engineering, Chemical Engineering, or related field.
• 5+ years of experience in materials engineering in automotive, defense, or related industry.
• Strong knowledge of metallic materials (e.g., steels, aluminum alloys) and/or polymers/composites, including processing and property relationships.
• Experience with material characterization and testing (e.g., tensile, hardness, microstructure, corrosion, coatings).
• Familiarity with engineering standards (e.g., GMW, ASTM, ISO) and drawing/specification practices.
• Demonstrated problem-solving skills and ability to lead cross-functional technical investigations.
• Experience applying materials engineering principles to automotive, defense, aerospace, or space systems, including understanding of how environment and mission profi
