  • Provide clear, well-documented written and verbal feedback on accept/reject decisions, supporting data-driven insights for AI model training.
  • Reference and apply NADCAP, AWS, ASTM, and AMS standards to a variety of metal samples, weldments, coatings, and AM builds.

Preferred Qualifications

  • At least 8 years of hands-on experience making high-stakes accept/reject calls on micrographs, weld macros, fracture surfaces, coatings, or LPBF additive builds.
  • Advanced knowledge of US and international standards including ASTM, AMS, AWS, NADCAP, NACE/AMPP, and SSPC.
  • Current or prior AWS Certified Welding Inspector (CWI) credentials, or equivalent metallurgical certification.
  • Proven experience in metallographic analysis, heat treatment evaluation, weld inspection, and industrial coating assessment.
  • Familiarity with additive manufacturing processes, especially laser powder bed fusion (LPBF) and associated defect mechanisms.
