3D Modeling & Python Specialist - Freelance AI Trainer Project

Agency; United States; Remote; USD 25,000 - 36,000; Part time

Job summary

Agency is seeking independent contractors to autonomously generate collision-accurate 3D meshes from 2D references using Blender Python (bpy) or Three.js/JavaScript. You will script procedural geometry generation, ensure precise mesh alignment, and export assets in common formats like .obj or .glb.

Deliver structured programmatic outputs (JSON/JS) to train AI systems, while logging trajectories for reproducibility.

Qualifications

• Proficient in Blender Python scripting (bpy) and/or Three.js/JavaScript.
• Able to write code to procedurally generate 3D assets; GUI-only work not enough.
• Understand geometric primitives and boolean operations for low-poly models.

Responsibilities

• Procedurally generate 3D geometry with Blender Python (bpy) or Three.js.
• Create collision-accurate meshes from 2D references and export to .obj/.glb.
• Produce JSON/JS outputs capturing build actions for reproducibility.
• Maintain trajectory logs and follow file naming conventions with high reliability.

Job description

Project Overview

We are sourcing independent 3D Modeling and Python Specialists to provide their 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 of this project 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: Writing 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: Producing collision-accurate meshes from 2D reference images (masked + RGB), capturing accurate screenshot alignments, and exporting assets to .obj, .glb, or similar formats.
• Structured Output & Trajectory Logging: Producing programmatic JSON/JS outputs representing the mesh and maintaining meticulous trajectory logs that capture sequential build actions for reproducibility.
• Quality Assurance & Workflow Adherence: Auditing all assets against strict quality checklists before submission, maintaining precise file naming conventions, and sustaining high-volume output within a structured annotation platform.

Required Expertise

To successfully fulfill the deliverables of this project, Contractors must possess a strong blend of 3D modeling fundamentals and programmatic scripting skills. Core skillset includes:

• 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 for this project.
• Deep understanding of geometric primitives (cubes, spheres, cylinders, cones) and Boolean operations, with a 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 the 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, or prior experience within AI/ML data annotation workflows.

Compensation

We offer a fixed pay rate of $22 per hour. As a contractor you’ll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
