Machining and Construction Reviewer, Part-Time AI Training - Remote (United States)

• $40–$60 per hour

• 100% remote

• Part-time

• About 10 hours a week, you choose when

Put your shop and field experience to work on paid AI training, on your own schedule.

AI training teams need experienced tradespeople and field leads to read real technical plans, judge how an AI system explains them, write the answer a seasoned professional would give, and point out what the system missed. Your practical judgment helps these systems give answers that hold up on a real shop floor or job site. The work is remote and part-time.

What you'll do

• Check machining drawings and GD&T callouts, and look over CNC setup and program sheets for weak practice or likely trouble

• Go through construction plan sets to find gaps, risks and places where the drawings could be clearer

• Judge drilling and mine plans for accuracy, feasibility and regulatory issues, and fire and building plans for safety and compliance

• Explain in plain written and spoken language how a plan would actually be carried out in the shop, on site, in a mine or in a fire-safety setting

Why this is worth your time

• Get paid $40–$60 an hour to apply your judgment to AI plan review work

• Work on AI systems that read technical drawings and field plans, rating their answers and helping them catch real-world problems

• Apply your shop and field judgment to AI plan review and clear written feedback

• Fully remote, no commute; you choose when you work

Who this is for

• 10 or more years of experience in one of these roles: master machinist, cabinetmaker, construction superintendent, fire officer, drilling engineer, or mine planner

• Strong skill reading technical drawings and field plans, with expertise in CNC programming, machining processes and applying GD&T

• Broad knowledge of US codes and standards for construction, fire, or mining, and hands-on experience reviewing fire and building plans with a focus on safety and regulations

• You can explain complex shop and field situations clearly, both in writing and in speech, and you are fluent in English

• Comfortable working on your own and giving detailed, high-quality feedback

• No AI experience needed.
