Javascript - Senior Developers - AI Training - Brighton, UK

Role overview Contribute professional JavaScript and TypeScript expertise to the training and evaluation of AI models. Work is task based: assess generated code and technical explanations, test outputs, and provide clear feedback that can help improve model performance. An initial skills assessment is required before joining the expert participant network.

Responsibilities - Review generated JavaScript and TypeScript for correctness, readability, and sound engineering practices. - Check whether explanations of algorithmic solutions follow valid reasoning. - Run scripts in Node.js or browser tools to confirm their behavior and performance. - Flag inefficient approaches, outdated syntax, or methods that do not exist. - Identify subtle defects, including memory issues and security weaknesses. - Give structured feedback on model responses about frontend and backend design.

Requirements - A bachelor’s, master’s, or doctoral degree in computer science, software engineering, or a related technical discipline. - Professional experience building scalable web applications with JavaScript or TypeScript. - Ability to solve independently challenging programming problems comparable to medium or hard algorithm exercises. - Strong knowledge of JavaScript execution, closures, prototypal inheritance, promises, and async/await. - A careful approach to clean, modular code using modern JavaScript standards. - Experience with frameworks such as React, Node.js, Vue, or Angular, and familiarity with APIs and testing tools.

Nice to have Experience with Jest or Cypress, Webpack or Vite, GraphQL, REST APIs, and server-side development in Node.js can be useful.
