Javascript - Senior Developers - AI Training UK

Use hands-on JavaScript engineering knowledge to help assess and improve AI-generated technical work. The assignment centers on reviewing code and reasoning, checking results by running scripts, and recording actionable observations. Candidates first complete a short assessment; successful applicants may then join a pool for paid tasks.

• Judge whether generated JavaScript and Type Script solutions work as intended and follow sound coding practices.
• Review explanations of complex algorithmic answers for gaps or invalid reasoning.
• Execute scripts in Node.js or a browser environment and inspect their output and performance.
• Point out inefficient implementations, obsolete syntax, and references to nonexistent library methods.
• Look for less obvious bugs, memory leaks, and security problems in generated code.
• Write structured feedback about model responses to frontend and backend architecture questions.

• A degree at bachelor’s level or above in computer science, software engineering, or a closely related field.
• Professional experience developing scalable web applications with JavaScript or Type Script.
• Confidence solving difficult coding problems independently, including medium and hard algorithm challenges.
• Expert understanding of the event loop, closures, prototypes, and asynchronous programming with promises and async/await.
• Strong code review judgment, with attention to clear, modular code and current ES6+ practices.
• Familiarity with modern JavaScript frameworks and web APIs.

Relevant experience may include React, Node.js, Vue, or Angular;
Jest or Cypress;
Webpack or Vite; REST or GraphQL APIs; and Node-based server logic.

Paid tasks are offered through an expert participant network. Advertised researcher rates can reach $50 per hour, with rates and task lengths varying; candidates should be able to set aside an uninterrupted hour when needed. The work is described as flexible and possible to do remotely. Entry includes a 10–15 minute skills assessment.
