Remote | mechanical design / cad expert — $60–$130/hour

We are sharing a specialised consulting opportunity for experienced Mechanical Design and CAD professionals with strong expertise in parametric modelling, GD&T, tolerance stack-up, design for manufacturability and assembly, production drawings, and engineering release workflows to contribute to an advanced AI training and mechanical-design evaluation project. Selected professionals will solve and review complex mechanical-design problems, assess AI-generated engineering responses, analyse production-ready designs, and provide rigorous feedback across CAD modelling, tolerancing, manufacturing constraints, and drawing release. No prior experience in AI is required.

Key Responsibilities

• Mechanical Design, CAD & Tolerancing
• Solve advanced part and assembly design problems across realistic production scenarios
• Review parametric CAD models for design intent, robustness, constraints, and maintainability
• Apply GD&T principles in accordance with ASME Y14.5
• Evaluate datum schemes, feature control frames, fits, interfaces, and dimensional requirements
• Perform or review worst-case and statistical tolerance stack-up analyses
• DFM/DFA & Production Release
• Evaluate designs for manufacturability and assembly across machining, sheet metal, injection moulding, casting, and related processes
• Identify tooling, access, draft, fixturing, assembly, and producibility constraints
• Review engineering drawings for dimensions, tolerances, notes, and release readiness
• Support concept-to-detail design development and ECR/ECN-related changes
• Recommend practical improvements balancing function, manufacturing, and reliability
• AI Evaluation & Technical Review
• Review AI-generated mechanical-design responses for technical correctness and practical applicability
• Identify incorrect assumptions, incomplete reasoning, or unrealistic design recommendations
• Distinguish substantive engineering issues from acceptable alternative approaches
• Provide clear, structured technical feedback supporting model improvement
• Collaborate remotely with other subject-matter experts and project participants

Ideal Profile

• BS or MS in Mechanical Engineering, Aerospace Engineering, Industrial Design, or a related discipline
• 5+ years of production-design or comparable mechanical-engineering experience
• Proven experience owning designs through GD&T, tolerance analysis, DFM/DFA, drawing release, and production
• Expert knowledge of parametric CAD modelling
• Strong knowledge of GD&T per ASME Y14.5 and tolerance stack-up analysis
• Experience with machining, sheet metal, injection moulding, casting, or related manufacturing processes
• Familiarity with SolidWorks, Creo, NX, CATIA, Inventor, or comparable CAD platforms
• PLM/PDM, CAM, CNC programming, or ASME B89 experience is advantageous
• CSWP or CSWE certification is a plus
• Strong technical problem-solving and communication skills
• Evidence of rigorous technical-review or problem-authoring experience, including standards work, competitions, publications, research recognition, or comparable achievements, is highly valued
• No prior AI-training or model-evaluation experience is required
