About the role
3D Modeling & Python Specialist - Freelance AI Trainer Project
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.
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.

Frequently asked questions
- What are the main responsibilities for a 3D Modeling & Python Specialist at Meridial Marketplace?
- As a 3D Modeling & Python Specialist for the AI Trainer Project, your primary responsibilities include autonomously generating collision-accurate 3D meshes from 2D references, writing Blender Python (bpy) or Three.js/JavaScript scripts for procedural geometry, and producing structured JSON/JS outputs for AI training. You'll also be responsible for quality assurance and adherence to strict workflow guidelines.
- Is GUI-only 3D modeling experience sufficient for this freelance role?
- No, GUI-only modeling experience is not sufficient for this project. The role explicitly requires demonstrable proficiency in writing code (Blender Python or Three.js/JavaScript) to generate 3D outputs. Practical scripting skills are a mandatory requirement for this position.
- What type of 3D modeling skills are preferred for this AI training project?
- The project prioritizes a deep understanding of geometric primitives (cubes, spheres, etc.) and Boolean operations for low-poly construction. Experience creating collision-accurate 3D meshes from 2D reference images is crucial. High-fidelity sculpting or subdivision-heavy modeling is less relevant for this specific AI data annotation task.
- What are the required deliverables for this freelance 3D modeling and Python project?
- Key deliverables include procedural geometry generation scripts, collision-accurate 3D meshes (exported as .obj, .glb, etc.), structured JSON/JS outputs detailing the mesh and build actions, and meticulous trajectory logs. You must also adhere to quality checklists and file naming conventions.
- Does Meridial Marketplace offer benefits for this freelance AI trainer role?
- This is a freelance / independent contractor role. As such, company-sponsored benefits such as health insurance and paid time off (PTO) do not apply. Contractors are responsible for their own secure computer and high-speed internet.
- How is the payment structured for the 3D Modeling & Python Specialist project?
- The project offers a fixed pay rate of $22 per hour for independent contractors. This rate is for the services provided, and contractors are responsible for their own equipment and internet.
- What level of detail is required for trajectory logging in this role?
- Meticulous trajectory logging is essential. This involves capturing sequential build actions precisely to ensure reproducibility of the 3D asset generation process. This detail is critical for training AI systems on geometric construction and logic.
