3D Modeling & Python Specialist - Freelance AI Trainer Project

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 entirely on robust, expert-crafted training data. The objective is to autonomously produce collision-accurate 3D meshes from 2D reference images, write procedural generation scripts, and deliver structured programmatic outputs (JSON/JS) to train AI systems on geometric construction and trajectory logic.

Project Deliverables & Scope

Operate autonomously to generate precise 3D assets and programmed outputs. Expected deliverables include:

• 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

Contractors must possess a strong blend of 3D modeling fundamentals and programmatic scripting skills.

• 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 does not qualify for this project.
• 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 (e.g., ZBrush).
• 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 Experience

• Background in game asset creation
• Familiarity with screen recording/keylogging tools
• Prior experience within AI/ML data annotation workflows

Compensation & Logistics

Fixed pay rate: $22 per hour. As a contractor, you will supply a secure computer and high-speed internet. Company-sponsored benefits such as health insurance and PTO do not apply.

Salary Disclosure: The annual salary range of $120,000–$170,000 USD is an editorial market estimate based on the stated hourly rate and typical annual engagement hours. This is not employer-provided compensation and may vary significantly based on actual hours worked, experience level, location, and project scope.
