Senior Metallurgist / Welding Inspector

Role Overview

Apply deep metallurgical and welding-inspection expertise to help train next-generation AI systems for advanced manufacturing and materials engineering. You will evaluate real-world technical cases, make defensible accept or reject decisions, and provide the expert reasoning needed to improve model performance. Prior AI experience is not required.

Key Responsibilities

• Evaluate metallographic microstructures for material acceptability and standards conformance.
• Analyze heat-treatment processes and perform acceptance reviews using AMS 2750, ASTM E112, and related U.S. specifications.
• Assess weld quality through macro-etch evaluation and apply CWI acceptance criteria to case studies.
• Conduct coating inspections aligned with NACE/AMPP and SSPC protocols, including surface-integrity and protection requirements.
• Review and disposition laser powder bed fusion, LPBF, additive-manufacturing defects using build and cross-sectional data.
• Provide clear written and verbal feedback supporting accept or reject decisions and data-driven AI training insights.
• Apply NADCAP, AWS, ASTM, and AMS standards across metal samples, weldments, coatings, and additive-manufacturing builds.

Qualifications

• At least 8 years of hands-on experience making high-stakes accept or reject decisions involving micrographs, weld macros, fracture surfaces, coatings, or LPBF builds.
• Advanced knowledge of ASTM, AMS, AWS, NADCAP, NACE/AMPP, and SSPC standards, including U.S. and international requirements.
• Current or previous AWS Certified Welding Inspector, CWI, credential, or an equivalent metallurgical certification.
• Demonstrated experience in metallographic analysis, heat-treatment evaluation, weld inspection, and industrial coating assessment.
• Familiarity with additive-manufacturing processes, particularly LPBF and related defect mechanisms.
• Excellent written and verbal communication skills, strong attention to detail, and the ability to clearly explain technical reasoning.
• Experience collaborating remotely or digitally, with strong self-direction and accountability for deliverables.

Work Terms

• Remote contract engagement, with U.S.-based candidates preferred.

Compensation

• $80 to $130 per hour.

Application Process

• Apply by email and acknowledge the applicable candidate terms and privacy policy as part of the application process.
