3D Modeling & Python Specialist – Freelance AI Trainer

Project Overview

We are sourcing independent 3D Modeling and Python Specialists to provide expertise for a specialized AI 3D asset collection project. As AI models increasingly generate and interact with 3D environments, their accuracy relies on robust, expert-crafted training data. This project involves autonomously producing collision-accurate 3D meshes from 2D reference images, writing procedural generation scripts, and delivering structured programmatic outputs (JSON/JS) to train AI systems on geometric construction and trajectory logic.

Project Deliverables & Scope

You will operate autonomously to generate precise 3D assets and programmed outputs:

• Procedural Geometry Generation: Write Blender Python (bpy) scripts or Three.js/JavaScript code to procedurally generate 3D geometry using geometric primitives and Boolean operations (union, subtraction, extrusion).
• Mesh Alignment & Export: Produce collision-accurate meshes from 2D reference images (masked + RGB), capture accurate screenshot alignments, and export assets to .obj, .glb, or similar formats.
• Structured Output & Trajectory Logging: Produce programmatic JSON/JS outputs representing the mesh and maintain meticulous trajectory logs capturing sequential build actions for reproducibility.
• Quality Assurance & Workflow Adherence: Audit all assets against strict quality checklists before submission, maintain precise file naming conventions, and sustain high-volume output within a structured annotation platform.

Required Expertise

Core skillset:

• Demonstrable proficiency in Blender Python scripting (bpy) and/or Three.js/JavaScript. Note: You must be able to write code to generate outputs; GUI-only modeling experience will not qualify.
• Deep understanding of geometric primitives (cubes, spheres, cylinders, cones) and Boolean operations, with focus on low-poly construction rather than high-fidelity, subdivision-heavy sculpting.
• Proven experience creating collision-accurate 3D meshes from 2D reference images.
• Highly detail-oriented with discipline to maintain trajectory logs, strictly follow file naming conventions, and self-audit work to maintain high reliability scores.
• Preferred: Background in game asset creation, familiarity with screen recording/keylogging tools, or prior experience in AI/ML data annotation workflows.

Compensation & Engagement Terms

This is a contractor role at a fixed rate of $22 per hour. As a contractor, you will supply your own secure computer and high-speed internet. Company-sponsored benefits such as health insurance and PTO do not apply.
