About The Position

GM Defense delivers integrated vehicles, power and propulsion, and autonomy and connectivity solutions to global defense, security, and government markets. The exceptional reliability of GM Defense’s technologies results from decades of proven performance and billions of dollars spent in independent research and development by its parent, General Motors, a world leader in global design, engineering, and manufacturing capabilities. 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.

Requirements

• 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 profile drive material selection and qualification.
• Candidate must be a U.S. Person (U.S. citizen, U.S. permanent resident, asylee or refugee).

Nice To Haves

• Experience with corrosion engineering, surface treatments, and protective coatings for automotive/defense applications.
• Experience working with suppliers and manufacturing plants (launch, quality, continuous improvement).
• Proficiency with data analysis tools and report writing for test and validation results.
• Vehicle launch experience
• General knowledge of cost drivers within the material forming space
• Advanced degree (MS/PhD) in Materials or related field.
• Experience with DoD and aerospace/space material and test standards (e.g., MIL-STD/MIL-PRF, MIL-STD-810, NASA materials and processes specifications) and associated qualification approaches.
• Background in materials for survivability and space environments, such as armor systems, high-temperature alloys, ceramic and composite materials, thermal protection systems, and radiation- or space-environment–tolerant polymers and coatings.
• Experience collaborating with U.S. Government/DoD customers on materials-related requirements, compliance, and data packages (e.g., qualification reports, material allowables, configuration-controlled specifications).

Responsibilities

• 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.
