About AI Training Work

AI training is the human side of building artificial intelligence. Experts review, rate, and explain model outputs so AI systems can produce more accurate, useful, and technically reliable results. In this project, your mechanical design judgment will help improve how AI reasons about CAD and production engineering.

• Work directly with AI-generated technical content
• Apply real-world engineering judgment to model evaluation
• Help refine the performance of state-of-the-art AI systems
• Complete flexible, remote work using your professional expertise

The Role

As a Mechanical Design and CAD Expert, you will evaluate and solve advanced mechanical design and computer-aided design problems. You will assess AI-generated technical responses for correctness, accuracy, and engineering quality while applying practical judgment to production design scenarios and theoretical questions.

This is an expert-level contractor role for professionals with substantial production design experience. The work focuses on mechanical engineering, parametric CAD, geometric dimensioning and tolerancing, tolerance analysis, and design for manufacturing and assembly.

• Role type: Contractor
• Work arrangement: Fully remote
• Experience level: Expert
• Expected availability: Under 20 hours per week
• Start timing: First tasks expected within 24 to 48 hours after onboarding

What You’ll Do

You will contribute both technical solutions and structured feedback that helps AI systems reason more effectively about mechanical design and CAD. Clear written and verbal communication will be important when documenting assessments and explaining engineering decisions.

• Evaluate and solve advanced part and assembly design problems
• Review AI-generated technical responses for technical correctness, accuracy, and engineering quality
• Analyze tolerance stack-ups and apply GD&T according to ASME Y14.5
• Troubleshoot production design problems using industry-standard methods
• Review designs for design-for-manufacturability and design-for-assembly considerations
• Apply engineering judgment to real-world production scenarios and theoretical questions
• Contribute mechanical design expertise to improve AI reasoning and model performance
• Document feedback and provide clear written and verbal explanations
• Collaborate remotely with distributed experts and project participants

Required and Preferred Qualifications

The preferred background is a BS or MS in Mechanical Engineering, Aerospace, or Industrial Design, together with at least five years of production design experience. You should have personally owned designs through GD&T, tolerance stack-ups, DFM review, drawing release, and production release.

The role requires professional fluency in English and exceptional written and verbal communication. Experience with the listed CAD, PLM, PDM, or manufacturing tools is beneficial but not required where identified as a plus.

• BS or MS in Mechanical Engineering, Aerospace, or Industrial Design preferred
• At least five years in production design roles preferred
• Expert knowledge of parametric CAD modeling
• Expert knowledge of GD&T per ASME Y14.5
• Expert knowledge of tolerance stack-up analysis
• Expert knowledge of design-for-manufacturability and design-for-assembly principles
• Ability to take designs from concept through detail drawings, ECR or ECN, and production release
• Familiarity with ASME Y14.5 and ASME B89 dimensional metrology standards
• Understanding of machining, sheet metal, injection molding, and casting constraints
• Professional or fluent English proficiency
• SolidWorks, Creo, NX, CATIA, Inventor, PLM, PDM, or CAM/CNC experience is a plus
• CSWP or CSWE certification is a plus

Problem-Authoring and Leadership Experience

The project strongly prefers evidence of rigorous problem authoring, technical leadership, or recognized engineering contribution. Relevant examples may come from academic, professional, competition, standards, or fellowship experience.

• Service on an olympiad problem committee
• Author credit for a textbook problem set or solutions manual
• Item-writer role on an NCEES or academic qualifying-exam committee
• Service on an ASME Y14.5, ASME B89, or related standards committee
• Top placement or team-lead role in Formula SAE or Formula Student
• Participation in ASME Student Design Competition, HPVC, MATE ROV, or a DARPA challenge
• An early-career fellowship or grant such as NSF CAREER, DOE Early Career, or Sloan Fellowship
• ASME Fellow recognition

Compensation and Project Details

Compensation is output-based. Experts are paid $90 USD per task that meets the project specifications. The time required may vary based on experience and workflow, and minimum submission requirements apply, including a minimum number of tasks per week.

• Compensation: $90 USD per qualifying task
• Payment model: Output-based, per task
• Expected weekly commitment: Under 20 hours
• Expected project duration: Under one month
