We are sharing a specialised part-time consulting opportunity for experienced CAD, mechanical-design, and computational-geometry professionals with strong expertise in Python, 3D modelling, engineering drawings, spatial reasoning, and programmatic CAD workflows to contribute to an advanced AI training and technical evaluation project.
Selected professionals will interpret dimensioned engineering schematics, reproduce them as precise 3D solid models, automate geometry creation through Python, and validate resulting models against strict geometric and physical requirements.
Despite the role title, this engagement is focused on CAD and mechanical geometry rather than general hardware support or electronics.
Key Responsibilities
Engineering Drawing Interpretation
Interpret dimensions, constraints, and geometric relationships from technical drawings
Translate 2D engineering schematics into accurate 3D mechanical models
Identify design intent from dimensioned views and technical annotations
Resolve geometric relationships across complex components
Maintain high dimensional accuracy throughout modelling workflows
3D CAD & Computational Geometry
Decompose complex mechanical components into appropriate geometric features
Model curved profiles, sweeps, lofts, fillets, chamfers, and Boolean operations
Build valid solid geometry suitable for downstream engineering use
Apply strong spatial reasoning when reconstructing parts from limited drawing information
Diagnose modelling approaches that produce incorrect or unstable geometry
Python & Programmatic CAD
Use Python to generate, automate, or manipulate CAD geometry
Develop reproducible modelling workflows using scripts or programmatic CAD libraries
Work with tools such as build123d, CadQuery, FreeCAD, OpenCascade, or comparable platforms
Integrate computational geometry into clean technical workflows
Ensure models can be regenerated consistently from code or scripted inputs
Model Validation & Geometric Verification
Export valid, watertight solid models in formats such as STEP
Validate dimensions, topology, volume, surface area, and inertia properties
Compare generated geometry against expected design requirements
Diagnose subtle differences between reference and generated models
Confirm that outputs satisfy both geometric and physical constraints
Technical Reproducibility & Quality
Produce solutions that work reliably in clean technical environments
Document modelling logic and validation steps clearly
Troubleshoot invalid geometry, broken solids, or modelling inconsistencies
Maintain reproducibility across CAD generation and verification workflows
Apply careful quality control to technically demanding geometry tasks
Ideal Profile
Strong Python programming ability
Hands-on experience with 3D CAD, computational geometry, or mechanical modelling
Ability to interpret dimensioned engineering drawings and schematics
Strong 3D spatial reasoning and attention to geometric precision
Experience validating, debugging, or troubleshooting CAD models
Familiarity with tools such as build123d, CadQuery, FreeCAD, OpenCascade, Fusion 360, Onshape, SolidWorks, trimesh, or comparable platforms
Experience with AutoCAD or other professional CAD environments is advantageous
Ability to work with complex curves, lofts, sweeps, fillets, chamfers, and Boolean geometry
Comfortable generating or modifying CAD programmatically
Formal education and fixed years of professional experience are not required where relevant skills can be demonstrated
Mechanical designers, CAD specialists, engineers, researchers, makers, and independent technical experts may all be suitable
Experience limited to general hardware support or electronics is not the focus of this engagement
Engagement Details
Part-time independent contractor engagement
Fully remote and open to candidates worldwide
Compensation: $50–$100/hour
Expected commitment: approximately 15 hours per week
Schedule is flexible, including the option to work evenings or weekends
Compensation is output-based, with payment made for tasks that meet project specifications
Minimum submission requirements apply
Work will involve CAD modelling, engineering-drawing interpretation, Python-based geometry generation, STEP export, and geometric validation
The selection process may include screening questions, an approximately 30-minute AI interview, and hiring-manager review
Selected professionals should be prepared to begin their first task within approximately 24–48 hours of completing onboarding
Roles are typically filled within approximately 48 hours
Work must be completed without using confidential or proprietary information belonging to any employer, client, institution, or other third party
