Javascript - Senior Developers - AI Training - Los Angeles USA

Role overview Help improve AI systems by applying hands-on JavaScript and TypeScript expertise to code review, testing, and evaluation. The work includes checking generated solutions and their explanations, confirming actual script behavior, and reporting where the model’s technical reasoning can be improved. Applicants complete a brief assessment, and successful candidates may be offered paid participant tasks.

Responsibilities - Inspect AI-generated code for correctness, maintainability, and alignment with modern practices. - Validate the logic behind algorithmic answers and their step-by-step explanations. - Run generated scripts in Node.js or browser tools and assess their outputs. - Identify performance problems, outdated syntax, and unsupported or invented APIs. - Catch subtle bugs, memory leaks, and security weaknesses such as XSS and prototype pollution. - Give clear feedback on model responses about frontend and backend architecture.

Requirements - Bachelor’s, master’s, or doctoral qualification in computer science, software engineering, or a related technical area. - Professional experience building scalable applications for the web with JavaScript or TypeScript. - Ability to independently solve medium- to hard-level coding problems in JavaScript. - Expert understanding of closures, the event loop, prototypal inheritance, and asynchronous patterns. - Strong attention to detail and a consistent approach to modular, readable ES6+ code. - Experience with a JavaScript framework or runtime such as React, Node.js, Vue, or Angular.

Nice to have Knowledge of Jest, Cypress, Webpack, Vite, REST or GraphQL APIs, and backend development in Node.js.
