Job description

We are seeking experienced Solar2D developers to support an AI training initiative focused on real-world 2D game development. In this role, you will use Solar2D (formerly Corona SDK) and Lua to complete practical game development tasks, demonstrate your technical workflows, and document your approach step by step.

Your expertise will help improve how AI systems understand, implement, and solve game development challenges. No prior AI experience is required; strong hands-on game development experience is what matters most.

Key Responsibilities

• Create, develop, and modify 2D games using Solar2D (Corona SDK).
• Write, maintain, and optimize Lua scripts for game functionality and interactive features.
• Design and implement game mechanics, player controls, animations, and user interface elements.
• Develop and refine physics systems, collision detection, movement logic, and interactive gameplay behavior.
• Debug code, identify technical issues, and resolve performance or functionality problems.
• Optimize game performance, responsiveness, and overall user experience across supported devices.
• Complete advanced Solar2D development tasks based on real-world game development scenarios.
• Record your screen while completing assigned tasks and demonstrate each stage of the development process.
• Explain technical decisions, coding methods, and development workflows in clear, step-by-step instructions.
• Create detailed prompts, task descriptions, and documentation for game development workflows.
• Deliver accurate, well-structured technical outputs within project guidelines and deadlines.

Required Qualifications

• Strong hands-on experience with Solar2D (Corona SDK).
• Good knowledge of Lua programming and 2D game development.
• Practical experience implementing game mechanics, animations, player controls, and user interface components.
• Familiarity with physics, collision detection, debugging, and performance optimization.
• Access to Solar2D and the ability to record your screen while completing development tasks.
• English proficiency at B2 level or higher.
• Strong technical communication skills and the ability to explain development workflows clearly.
• Attention to detail and the ability to work independently in a remote environment.

Preferred Qualifications

• A portfolio demonstrating Solar2D projects or other 2D game development work.
• Experience developing mobile games for Android or iOS.
• A relevant master's degree or PhD in computer science, software engineering, game development, or a related field.
• Previous experience in Human Data projects, including data annotation, reinforcement learning from human feedback (RLHF), or AI model evaluation.
• Experience documenting technical workflows, creating development tasks, or evaluating programming solutions.
