Metallurgist and Welding Inspector, Part-Time AI Evaluation - Remote (United States)

• $80–$130 per hour

• 100% remote

• Part-time

• 20 or more hours a week, you choose when

Work on the cutting edge of AI, on your own schedule, and get paid for the inspection judgment you already have.

The AI systems everyone is talking about are trained and tested by real experts. The teams building them need metallurgists and welding inspectors who can create realistic inspection cases, judge how well the AI handles them, write the decision a professional would make, and explain exactly where the AI falls short. Your standards-based judgment becomes part of how the next generation of AI models works. This is that work, done remotely, around your current job.

What you’ll do

• Evaluate metallographic microstructures and heat-treatment evidence against applicable standards

• Assess weld quality through macro-etch evaluation and apply Certified Welding Inspector acceptance criteria

• Review coating inspection evidence against NACE/AMPP and SSPC protocols

• Identify and disposition defects in laser powder bed fusion metal 3D-printing builds, then explain the accept-or-reject decision clearly

Why this is worth your time

• Get paid $80–$130 an hour to build real AI skills, on top of your current job

• Work directly with frontier AI tools and see how they are built, tested and improved, experience most metallurgists and welding inspectors will not have for years

• Build a career edge for what comes next: AI is reshaping materials engineering and advanced manufacturing, and the people who understand it from the inside will lead that change

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• A US-based professional with at least eight years making accept-or-reject decisions involving micrographs, weld macros, fracture surfaces, coatings, or laser powder bed fusion additive builds

• Hands-on expertise in metallographic analysis, heat-treatment evaluation, weld inspection, and industrial coating assessment, with knowledge of ASTM, AMS, AWS, NADCAP, NACE/AMPP, and SSPC standards

• Clear written and spoken English, with the ability to explain inspection reasoning and technical decisions clearly

• No AI experience needed. You bring the expertise; we bring the training on the tools.

Pay and details

• $80–$130 per hour, paid hourly as an independent contractor

• 20 or more hours a week, you choose when; fully remote, United States
