We are sharing a specialised consulting opportunity for experienced Senior Mechanical Design Engineers with deep expertise in complex multi-part assemblies, parametric CAD, mechanism design, kinematic analysis, GD&T, tolerance judgement, and design review to contribute to advanced AI training and mechanical-engineering evaluation initiatives. Selected professionals will analyse complex CAD assemblies, formulate challenging engineering questions, validate exact answers from models, review AI-generated mechanical reasoning, and document edge cases with strong technical precision. No prior AI experience is required; advanced mechanical-design expertise is the primary qualification. Key Responsibilities Mechanical Assembly Analysis • Analyse complex multi-part mechanical assemblies • Identify critical design decisions and engineering constraints • Evaluate component relationships, interfaces, and assembly intent • Identify potential failure points requiring expert judgement • Apply practical mechanical-design reasoning beyond drawing interpretation Technical Question Development • Formulate challenging mechanical-design questions from CAD models • Focus on non-obvious problems requiring senior-level engineering judgement • Develop questions involving assemblies, mechanisms, tolerances, and constraints • Avoid trivial or purely visual questions • Ensure questions are technically meaningful and answerable CAD Validation & Exact Answer Development • Validate answers directly against underlying CAD models • Document exact and defensible engineering conclusions • Maintain clear traceability between questions and model evidence • Identify relevant dimensions, constraints, and geometric relationships • Ensure answers remain precise and technically reproducible AI Output Review & Mechanical Reasoning • Review AI-generated responses to mechanical-engineering questions • Identify breakdowns in design intent or assembly reasoning • Evaluate mechanism and kinematic interpretation • Flag incorrect GD&T or tolerance assumptions • Recommend targeted improvements to technical reasoning quality Quality Review & Technical Documentation • Identify ambiguous, trivial, or unanswerable questions • Refine technical prompts for clarity and precision • Document edge cases and legitimate sources of disagreement • Communicate findings through clear professional documentation • Support consistent quality standards across evaluation workflows Ideal Profile • 5+ years of professional mechanical-design experience • Experience creating and overseeing multi-part assemblies from concept • Strong ability to make original mechanical-design decisions rather than working only from existing drawings • Mastery of at least one major parametric CAD platform • Relevant tools may include SolidWorks, Creo, NX, CATIA, Inventor, Fusion, Onshape, or Solid Edge • Deep expertise in design intent and assembly reasoning • Strong mechanism and kinematic analysis capabilities • Advanced understanding of GD&T and tolerance judgement • Experience identifying design constraints and failure modes • Strong technical reasoning across complex mechanical systems • Experience teaching, mentoring, leading design reviews, or coaching engineering teams • Exceptional written English communication skills • Strong ability to document technical reasoning precisely • Experience in industrial machinery, automation, robotics, automotive, heavy equipment, aerospace, defence, medical devices, consumer products, tooling, or fixture design • FreeCAD experience is advantageous • Advanced tolerance analysis or formal design-review leadership is advantageous • No prior AI-training or model-evaluation experience is required Engagement Details • Independent contractor engagement • Fully remote • Expected commitment: approximately 15 hours per week • Compensation: $40–$90/hour • Work will involve CAD assembly analysis, mechanical-reasoning question development, answer validation, AI-output review, and technical documentation • Strong parametric CAD expertise is central to this engagement • Assignments may involve design intent, mechanism analysis, kinematics, GD&T, tolerance assessment, and failure-point identification • Contributors will be expected to distinguish technically meaningful questions from ambiguous or trivial ones • Documentation must support clear traceability and reproducibility • Project scope, CAD models, and engineering scenarios may vary depending on project requirements • Work must be completed without using confidential, proprietary, export-controlled, classified, client-restricted, or otherwise protected designs, CAD files, drawings, technical data, or documentation belonging to any employer, client, institution, or other third party About the Platform This opportunity is available through 24-MAG LLC.
