Role overview

Apply professional JavaScript and TypeScript knowledge to help train and assess AI models. The work focuses on examining generated code and its explanations, running scripts to check their behavior, and supplying clear feedback about technical quality. Candidates first complete a short skills assessment; those who pass may be invited to take paid tasks as participants.

Responsibilities

• Review generated JavaScript and TypeScript for functional accuracy and sound coding practices.
• Evaluate the reasoning behind algorithmic solutions and check for logical errors.
• Run scripts in Node.js or browser environments to confirm results and performance.
• Point out inefficient code, obsolete syntax, or invented library functionality.
• Find subtle defects, memory leaks, and security risks, including cross-site scripting and prototype pollution.
• Write structured feedback on model discussions of frontend and backend architecture.

Requirements

• Degree in computer science, software engineering, or a closely related technical discipline at bachelor’s level or above.
• Professional background developing scalable web applications with JavaScript or TypeScript.
• Confidence solving medium- to hard-difficulty programming challenges in JavaScript without assistance.
• Expert grasp of JavaScript execution, closures, prototypal inheritance, and asynchronous programming patterns.
• Strong judgment about readable, modular code and current ES6+ conventions.
• Familiarity with a major JavaScript framework or runtime such as React, Node.js, Vue, or Angular.

Nice to have

• Hands-on knowledge of Jest, Cypress, Webpack, Vite, REST or GraphQL APIs, and Node.js server-side development.
