About AI training and why this work matters

AI training (data labeling/annotation) is the human side of building intelligent systems — people prepare, test, and refine examples that teach models how to behave. This work is in high demand, highly flexible, and often accessible to developers, designers, and creatives.

Contributors often choose this work for its remote flexibility, part-time options, and direct impact on cutting-edge AI behavior. Many projects accept people at entry level if they bring relevant skills like engine experience, strong attention to detail, and good communication.

The role

OpenTrain AI is hiring a Cocos2d-x Game Developer to produce robust 2D gameplay and game assets that serve as high-quality input for AI training and data-generation projects. This is contract, part-time work (20+ hours/week) done remotely and open worldwide; English is required.

Compensation is hourly, with a range of $50–$110 USD per hour (top rate $110/hr). This role is entry-level friendly but requires proven hands-on Cocos2d-x experience and the ability to follow technical specifications and iterate from feedback.

• Employment type: Contractor, Part-time
• Time commitment: 20+ hours/week (remote, distributed collaboration)
• Language: English (working proficiency required)
• Pay: $50–$110 USD per hour (PAY_PER_HOUR; max listed $110/hr)

What you’ll do

You will implement, test, and document 2D game features and scenes in Cocos2d-x so they can be used as training inputs and evaluation assets for AI systems. Work is iterative and feedback-driven; clear artifacts and readable code are important deliverables.

• Build and refine game logic, mechanics, and features using Cocos2d-x.
• Create, modify, troubleshoot, and optimize game assets and scenes for reliable playback and data capture.
• Test and debug Cocos2d-x code to ensure efficient, stable gameplay behavior.
• Document code, scene setups, and processes clearly for technical and non-technical stakeholders.
• Communicate progress, blockers, and updates with distributed collaborators and iterate on feedback.

Requirements and qualifications

Candidates must demonstrate practical Cocos2d-x experience and the ability to produce working 2D game logic and assets. Strong problem-solving, attention to detail, and clear written/verbal communication for remote collaboration are required.

• Proven hands-on Cocos2d-x development experience (projects, repo links, or portfolio expected).
• Ability to build and troubleshoot 2D game logic, mechanics, assets, and scenes.
• Clear written and verbal communication for distributed teamwork and documentation.
• Comfort working from technical specifications and iterating based on feedback.
• Understanding of game design principles and player-experience optimization.
• Experience with AI training or data-generation projects is preferred; familiarity with other engines or languages is a plus.
