About this opportunity
Role Title: Senior Metallurgist / Welding Inspector
Role Type: Contractor
Location: Remote (US based preferred)
micro1 is engaging expert Senior Metallurgists and Welding Inspectors to participate in a high-impact project for a customer in advanced manufacturing and materials engineering. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.
Scope of Work
- Evaluate and interpret metallographic microstructures to determine material acceptability and conformance to standards.
- Conduct heat treatment process analysis and acceptance reviews in accordance with AMS 2750, ASTM E112, and related US specifications.
- Assess weld quality through macro etch evaluation and apply CWI acceptance criteria to real-world case studies.
- Perform coating inspection tasks aligned with NACE/AMPP and SSPC protocols, ensuring surface integrity and protection requirements are met.
- Review and disposition additive manufacturing (LPBF) defects based on detailed build and cross-sectional data.
- 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.
- Exceptional written and verbal communication skills, with a keen eye for detail and the ability to explain technical reasoning clearly.
- Experience in remote or digital project collaboration, with strong self-direction and accountability for deliverables.
