Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your development skills are what matter. As an expert, you will be creating Reinforcement Learning Environments which test an AI model's ability to solve full-stack software problems, spanning frontend, backend, and the connection between them. You will be tasked with creating a reproducible environment and a golden reference solution for the problem. Scope of Work • Contribute clear code samples, debugging approaches, and development insights across frontend and backend, using languages like JavaScript/TypeScript, Python3, Java, or Go. • Identify, troubleshoot, and resolve bugs that span both the UI and the underlying API or database layer. • Build small to medium features end-to-end, from the interface through to the data layer, following good coding practices. • Improve existing frontend and backend code to make it cleaner, more consistent, and easier to maintain. • Document your reasoning, approach, and code decisions to support AI training data quality. • Review peer-contributed code and technical submissions for correctness and clarity. Preferred Qualifications • 1+ years of hands-on experience building both frontend and backend applications. • Comfortable with at least one frontend framework (React, Vue, or Angular) and one backend stack (Node/Express, Python/Django/Flask, Java/Spring, or similar). • Solid understanding of how frontend and backend systems connect through APIs. • Ability to debug issues that cross the frontend/backend boundary. • Good documentation and communication skills to explain your technical decisions clearly. • Interest in or curiosity about AI and its technical challenges (previous AI experience not required).
