You will be the primary technical authority for interpreting complex aerospace and industrial specifications, ensuring that all products meet the highest standards of quality and performance.

• Provide technical oversight and optimization for Vacuum Induction Melting (VIM) processes to ensure chemical homogeneity and cleanliness of superalloy heats.

• Manage and refine operating parameters, including refractory preparation, melt profile, additions, filtration, and pouring temperatures, .

• Troubleshoot production issues related to alloy chemistry and manufacturing.

• Specification Interpretation: Act as the lead technical point of contact for interpreting customer, industry (AMS, ASTM, ASME), and internal material specifications.

• Quality Management: Ensure all manufacturing processes and final products comply with internal, customer, AS9100, ISO 9001, and NADCAP requirements.

• Develop and approve Method of Manufacture (MoM) documentation and Material Control Plans.

• Provide oversight on metallurgical testing protocols, including chemistry, metallography , and physical testing .

• Lead Root Cause Analysis (RCA) and Corrective Action (CAPA) investigations for material or process failures.

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

• A minimum of 5 years of hands-on experience in a metallurgical role specifically focused on nickel-, cobalt-, or iron-based superalloys.

• Proven experience with Vacuum Induction Melting (VIM) and/or VAR/ESR processes.

• Direct experience in an Investment Casting foundry environment.

• Strong understanding of solidification theory and phase transformations in complex alloy systems.

• Compliance: Demonstrated ability to interpret and apply complex aerospace/defense specifications.
• Experience with casting simulation software (e.g., ProCAST or Magma).

• Six Sigma Green or Black Belt certification.

• Prior experience interfacing with Tier 1 aerospace OEMs.

• Ability to sit or stand for extended periods and move throughout the office as needed.

• Regular use of hands for typing, writing, and computer work.

• Ability to lift or carry light office items (typically up to 15 lbs).

• Work performed in a standard office environment with moderate noise and routine interruptions.

• Ability to read screens, documents, and electronic communications with clarity.

• Occasional extended hours during peak HR cycles (onboarding, payroll deadlines, audits).

• Ability to maintain confidentiality and handle sensitive information in shared office spaces.

• Occasional time spent on the manufacturing floor and supplier visits as required.

• Ability to work standard business hours with flexibility during production or supply disruptions.

• Must be able to comply with all safety and PPE requirements when entering production areas.
