• Create, develop, and optimize material and process specifications related to graphite and other mechanical components
• Write specifications, process control, and quality control plans for graphite and other mechanical components
• Collaborate with other teams such as mechanical design, supply chain and quality to qualify processes and establish key process controls at manufacturing locations
• Participate in FMEA for design, process and maintenance
• Support the Materials and Process team with failure analysis and process development projects in other areas

• MS in Materials Science/Engineering or Mechanical Engineering
• MS + 5 years or PhD + 3 years of industry experience
• Deep understanding of isostatic graphite structure, properties and performance, including graphite manufacturing processes
• Fundamental understanding of properties and performance of engineering materials, and basic knowledge of structure‑property relationships
• Experience with volume production of graphite components is highly preferred
• Knowledge of dry (solid lubrication) tribology relative to ceramic or graphite materials is highly preferred
• Working knowledge and experience with FMEA (Failure Mode and Effects Analysis)
• Demonstrated experience with statistical data analysis and reporting (Matlab/Python, Google Sheets/Excel, Weibull++, etc.)
• Excellent communication skills, adaptable self‑starter, enjoys collaboration in a fast‑paced environment
