Job description

Role overview

Use professional JavaScript and TypeScript expertise to assess and improve AI-generated code and technical reasoning. Work is task-based: after a short skills assessment, successful candidates may be invited to complete paid evaluation and training tasks, some of which require an uninterrupted hour.

Responsibilities

• Check generated JavaScript and TypeScript for correctness, readability, and modern coding practices.


• Assess whether explanations for algorithmic solutions are logically sound.


• Run scripts in Node.js or browser tools to verify behavior and performance.


• Flag inefficient approaches, outdated syntax, nonexistent library methods, security weaknesses, and memory leaks.


• Give structured feedback on the models' reasoning about frontend and backend design.

Requirements

• A bachelor's, master's, or doctoral degree in computer science, software engineering, or a closely related technical field.


• Professional experience building scalable web applications with JavaScript or TypeScript.


• Ability to solve medium- to hard-level algorithm problems independently in JavaScript.


• Strong knowledge of the event loop, closures, prototype inheritance, Promises, and async/await.


• Careful, modular coding practices and familiarity with modern ES6+ JavaScript.


• Ability to identify subtle logic errors and risks such as cross-site scripting or prototype pollution.

Nice to have

• Experience with React, Node.js, Vue, or Angular; testing tools such as Jest or Cypress; and build tools such as Webpack or Vite.


• Familiarity with REST APIs, GraphQL, and server-side development in Node.js.

Benefits and work setup

• Tasks are paid, with rates reported by researchers of up to $50 per hour; actual task availability and rates may vary. Some tasks are shorter than an hour, while others require a full uninterrupted hour.


• Flexible scheduling and remote participation are described. A brief assessment of about 10-15 minutes precedes possible access to tasks.
