About AI Training Work
AI training is the human side of building artificial intelligence. Specialists provide examples, evaluations, technical judgments, and feedback that help AI models reason more accurately and produce higher-quality results.
In this project, your mechanical engineering and parametric CAD expertise will support high-quality 3D sensor labeling, text generation, evaluation, and review tasks. Your professional judgment matters more than prior experience in AI.
Work on cutting-edge AI development
Apply practical CAD and manufacturing knowledge
Help improve how AI systems understand technical information
The Role
OpenTrain is seeking an Autodesk Fusion 360 Specialist with strong experience in advanced parametric CAD modeling. The project focuses on creating, editing, auditing, and documenting mechanical parts and assemblies, with FreeCAD as the primary software environment.
Strong 3D parametric CAD experience in Autodesk Fusion 360, SolidWorks, or Inventor can transfer directly to the work. Prior FreeCAD experience is ideal, but the central requirement is deep expertise in parametric modeling and mechanical design.
Role type: Contractor
Location: Remote and worldwide
Primary focus: Mechanical engineering and parametric CAD modeling
Fluent English proficiency required
What You'll Do
You will create and review accurate, robust CAD work from detailed written briefs while clearly documenting design decisions. You will also contribute to evaluation and text-generation activities connected to AI model training.
Develop fully parametric 3D models of mechanical parts and assemblies
Build robust sketches, constraints, and feature trees
Edit existing parametric CAD models as requirements change
Audit models for dimensional accuracy, tolerance application, and design intent
Identify gaps or deviations in CAD models and specifications
Apply design-for-manufacturability knowledge to production-oriented designs
Use knowledge of injection molding, sheet metal, CNC machining, and casting or forging
Support N 3D sensor labeling workflows
Complete evaluation rating and text generation tasks
Communicate design rationale, feedback, and technical insights clearly
Provide consistent CAD data and technical documentation for AI training
Required Expertise
The project is listed at an entry-level classification, while the assignment requirements include substantial applied CAD and manufacturing expertise. Model editing tasks call for 4 or more years of applied experience, and complex model creation assignments call for 10 or more years.
