Senior Metallurgist / Welding Inspector

$80–$130/h

Remote (US based preferred)

Role overview

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

  1. Evaluate and interpret metallographic microstructures to determine material acceptability and conformance to standards.
  2. Conduct heat treatment process analysis and acceptance reviews in accordance with AMS 2750, ASTM E112, and related US specifications.
  3. Assess weld quality through macro etch evaluation and apply CWI acceptance criteria to real-world case studies.
  4. Perform coating inspection tasks aligned with NACE/AMPP and SSPC protocols, ensuring surface integrity and protection requirements are met.
  5. Review and disposition additive manufacturing (LPBF) defects based on detailed build and cross-sectional data.
  6. Provide clear, well-documented written and verbal feedback on accept/reject decisions, supporting data-driven insights for AI model training.
  7. Reference and apply NADCAP, AWS, ASTM, and AMS standards to a variety of metal samples, weldments, coatings, and AM builds.


Preferred Qualifications

  1. 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.
  2. Advanced knowledge of US and international standards including ASTM, AMS, AWS, NADCAP, NACE/AMPP, and SSPC.
  3. Current or prior AWS Certified Welding Inspector (CWI) credentials, or equivalent metallurgical certification.
  4. Proven experience in metallographic analysis, heat treatment evaluation, weld inspection, and industrial coating assessment.
  5. Familiarity with additive manufacturing processes, especially laser powder bed fusion (LPBF) and associated defect mechanisms.
  6. Exceptional written and verbal communication skills, with a keen eye for detail and the ability to explain technical reasoning clearly.
  7. Experience in remote or digital project collaboration, with strong self-direction and accountability for deliverables.

How big is the remote / hybrid opportunity?

Remote work is already huge — but the bigger story may be the hundreds of millions of jobs that could still move beyond geography.

Global remote and hybrid work opportunity infographic

Remote work already connects millions of people with companies they would never have been able to work for a decade ago. But compared with the size of the global labour market, it may still be early.

The interesting number is not only how many people work remotely today — it is how many roles could plausibly become remote or hybrid next.

The chart above starts with roughly 3.3 billion people employed worldwide. Around 300 million jobs are already remote or hybrid, while an additional pool of roughly 250 million roles could potentially move in that direction as technology, workflows and company culture continue to change.

Skills are becoming more portable

This matters because more work can increasingly be matched to expertise rather than location. AI training and evaluation are a good example: companies need lawyers, engineers, designers, editors, researchers, finance professionals and many other specialists to help improve AI systems.

For workers, that creates access to projects outside their local market. For companies, it expands the talent pool from one city or country to the world.
