OpenTrain AI is the platform and contracting organization where people build careers in AI training and data labeling. We connect contributors with hands-on projects that help shape state-of-the-art models while supporting flexible, remote work that fits varied schedules.
Working with OpenTrain AI means contributing to the human side of AI—preparing the examples and simulations modern models learn from—while keeping a portable portfolio of completed projects and technical contributions.
About AI Training Work
AI training (data labeling / annotation) is how humans teach models to understand the world. For simulation and game-based training, developers create robust 3D environments and logic that generate training data, test behavior, and stress models under realistic conditions.
This role sits at the intersection of game development and model training: it requires software engineering rigor, an eye for performance across hardware, and clear documentation so simulated scenarios can be reused and scaled.
The Role
OpenTrain AI is hiring a Python Game Developer focused on Panda3D to design, develop, and optimize 3D simulations and environments used for AI training. This is a contract, part-time role (20+ hours/week) that is fully remote and worldwide.
You will work directly on Python and C++ codebases, maintain cross-platform compatibility, participate in code reviews, and document architecture and technical decisions to support collaborative development.
Employment type: Contractor, Part-time
Time requirement: 20+ hours/week
Work location: Remote, worldwide (English required)
Pay: Hourly — USD $50–$120/hr (posted hourly rate up to $120/hr)
What You'll Do
Deliver production-ready 3D simulations and environment logic using Panda3D that support model training and evaluation. Ensure scenes and systems perform well across hardware profiles.
Maintain and improve mixed Python and C++ codebases, troubleshoot crashes and performance issues, and keep code cross-platform on Windows, macOS, and Linux.
Build and optimize Panda3D scenes, simulations, and game systems for AI training.
Debug, refactor, and extend Python and C++ code integrated with Panda3D.
Use GitHub workflows: branching, pull requests, and code review etiquette.
Document architecture, design decisions, and setup steps for team use.
Participate in code reviews, design discussions, and regular team syncs.
Requirements
Candidates must provide demonstrable, hands-on Panda3D development experience and strong programming ability in both Python and C++. You should be comfortable working independently in a remote setting and meeting agreed deadlines.
Clear written and verbal communication is essential for distributed collaboration; you will be expected to write clear technical notes and contribute to review processes.
Hands-on Panda3D development experience (required).
Advanced Python and C++ programming skills (required).
Solid understanding of 3D graphics pipelines, simulation logic, and cross-platform optimization.
Attention to detail, problem-solving mindset, and ability to work independently.
Helpful Background
Experience building game systems or simulation environments intended for training or testing AI models is a strong advantage. Familiarity with asset optimization and ensuring stable performance across varied hardware will help you succeed.
Experience with distributed Agile collaboration, asset pipelines, and profiling/performance tools is useful but not mandatory.
Game development for AI, simulation, or training use cases.
Optimizing 3D assets and scenes for performance across hardware.
Familiarity with distributed Agile collaboration and tooling.
How It Works / Apply
OpenTrain AI hires and contracts directly for this role. If you meet the requirements, apply with examples of your Panda3D work (repositories, demos, or code snippets) and a short note about relevant projects and availability.
Selections will focus on demonstrated Panda3D experience, Python/C++ code samples, and evidence of cross-platform and performance work. OpenTrain accounts are free to create and let you manage your profile and project history.
Prepare links to Panda3D projects, code samples, or demos.
Be ready to discuss past simulations, performance fixes, and cross-platform issues during technical screening.
