Junior Open 3D Engine Software Engineer

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We help freelancers discover projects, consolidate opportunities, and build a unified AI training portfolio that they control.

OpenTrain AI is the hiring and contracting organization for this role. We focus on practical, flexible work that helps people start and grow careers shaping how AI systems learn.

Why AI training and simulation work matters

Human-created simulations and synthetic data are essential to modern AI development. Contributors build environments, label behavior, and validate outputs so models learn from accurate examples.

This work is often 100% remote and flexible, accessible to those with hands-on technical skills, and lets you directly influence how state-of-the-art systems behave.

The role

You will be a Junior Open 3D Engine (O3DE) Software Engineer building interactive 3D scenes and simulations used to generate synthetic data for AI training. This is a contract, part-time position requiring 20+ hours per week and remote work.

Pay is hourly (PAY_PER_HOUR). The project lists a wide rate range ($20–$120/hr); final compensation depends on the task complexity, your verified experience, and negotiated scope.
