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.

Key Responsibilities

Process Engineering & Melting

• 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 & Quality Compliance

• 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.
  
  

Testing & Characterization

• 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.
  
  

Required Qualifications

• 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.
  
  

Preferred Qualifications

• 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.
  
  

Physical & Work Environment Requirements

• 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).
