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 technical feedback across part and assembly design, dimensional tolerancing, manufacturing constraints, and drawing release. The work requires strong hands-on production-design experience, precise engineering judgement, and clear written communication. No prior experience in AI is required.

Key Responsibilities

Mechanical Design & CAD Problem Solving

• Solve advanced mechanical-design and CAD problems
• Analyse part and assembly design challenges
• Evaluate geometry, interfaces, fits, and functional requirements
• Apply practical production-design judgement to realistic engineering scenarios
• Develop technically sound solutions that reflect manufacturing constraints

Parametric CAD Modelling

• Review and assess parametric CAD models
• Evaluate design intent and modelling strategy
• Identify fragile, inefficient, or poorly constrained feature structures
• Recommend improvements to model robustness and maintainability
• Apply professional CAD practices across complex parts and assemblies

GD&T & ASME Y14.5

• Apply GD&T principles in accordance with ASME Y14.5
• Review datum strategies, feature control frames, and tolerance schemes
• Assess whether geometric controls match functional design intent
• Identify over-constrained, under-defined, or impractical tolerancing
• Provide clear explanations of dimensional and geometric requirements

Tolerance Stack-Up Analysis

• Perform and review tolerance stack-up analyses
• Evaluate worst-case and statistical tolerance effects where appropriate
• Identify critical dimensional chains
• Assess whether tolerances support functional and manufacturing requirements
• Recommend practical adjustments balancing performance and producibility

Design for Manufacturability & Assembly

• Evaluate designs for manufacturability and assembly
• Identify issues related to machining, sheet metal, injection moulding, casting, or comparable processes
• Review geometry for tooling, access, draft, fixturing, and assembly constraints
• Recommend changes that improve manufacturability without compromising function
• Apply realistic production considerations to design decisions

Drawing Release & Change Control

• Review engineering drawings for release readiness
• Assess dimensional completeness, notes, tolerances, and manufacturing information
• Support concept-to-detail drawing development
• Evaluate ECR/ECN-related design changes
• Apply professional standards to production-release documentation

AI Engineering Evaluation

• Review AI-generated mechanical-design responses
• Assess technical correctness, engineering quality, and practical applicability
• Identify incorrect assumptions or incomplete reasoning
• Provide structured feedback to improve model performance
• Distinguish genuine engineering errors from acceptable alternative approaches

Technical Communication & Collaboration

• Document engineering feedback clearly and precisely
• Explain complex design concepts in professional written and verbal formats
• Collaborate remotely with other subject-matter experts and project participants
• Support consistency across evaluation tasks and technical review criteria
• Contribute practical production-engineering context to AI training workflows

Ideal Profile

• BS or MS in Mechanical Engineering, Aerospace Engineering, Industrial Design, or a related discipline
• 5+ years of experience in production design or comparable mechanical-engineering roles
• Proven experience personally owning designs through GD&T, tolerance analysis, DFM, and drawing release
• Expert knowledge of parametric CAD modelling
• Strong knowledge of GD&T per ASME Y14.5
• Strong tolerance stack-up analysis skills
• Demonstrated experience with design for manufacturability and assembly
• Ability to take designs from concept through detailed drawings and production release
• Familiarity with ASME B89 dimensional-metrology standards is advantageous
• Strong understanding of manufacturing-process constraints
• Experience with machining, sheet metal, injection moulding, casting, or related processes
• Familiarity with SolidWorks, Creo, NX, CATIA, Inventor, or comparable CAD platforms
• Experience with PLM/PDM systems is advantageous
• CAM or CNC programming experience is beneficial
• CSWP or CSWE certification is a plus
• Professional English proficiency
• Exceptional written and verbal technical communication skills
• Evidence of rigorous engineering problem-authoring or technical-review experience is highly valued, including standards-committee work, competition leadership, examination item writing, textbook authorship, research recognition, or comparable achievements
• No prior AI-training or model-evaluation experience is required

Engagement Details

• Independent contractor engagement
• Fully remote
• Displayed compensation range: $60–$130/hour
• Actual compensation structure is output-based, with payment made per task that meets project specifications
• Task completion time may vary depending on individual experience and workflow
• Minimum weekly submission requirements apply; the source does not specify the exact number of required tasks
• Work will involve mechanical design, CAD modelling, GD&T, tolerance stack-up, DFM/DFA, production drawing review, and AI-generated engineering-content evaluation
• Strong hands-on production-design experience is central to this engagement
• Roles are typically filled within approximately 48 hours
• Selected experts are expected to begin initial tasks within approximately 24–48 hours after onboarding
• Project scope, workload, design problems, and evaluation standards may evolve depending on project requirements
• Work must be completed without using confidential or proprietary information belonging to any employer, client, manufacturer, engineering organisation, institution, or other third party
