Job Description

We’re hiring Frontend Developers to help train and evaluate next-generation coding agents and AI systems. In this role, you’ll build small to mid-sized web application features, validate AI-generated code, and provide structured feedback on UI/UX decisions and implementation quality. This position is ideal for developers with 2–6 years of experience who are strong in a modern JavaScript framework and comfortable working with AI-assisted development tools. Depending on your portfolio strength, you may be matched with one of two active projects that range from high-volume development tasks to more design-focused frontend builds.

Job Responsibility

  • Develop and maintain modern web interfaces using your strongest frontend framework
  • Review, test, and refine code generated by AI coding assistants
  • Implement clean, reusable, and maintainable components
  • Apply strong CSS fundamentals, including Tailwind, Bootstrap, or custom styling approaches
  • Provide feedback on layout, accessibility, and UI/UX clarity
  • Follow detailed project guidelines for evaluation integrity and task consistency
  • Communicate clearly with project coordinators and follow milestone-based task delivery

Requirements

  • 2–6 years of experience in frontend or fullstack development
  • Proficiency in at least one modern framework: React, Next.js, Vue, Angular, or Svelte
  • Strong CSS fundamentals and experience with component libraries or design systems
  • Ability to interpret design specifications and translate them into clean UI implementations
  • Familiarity with Git, modern tooling, and common frontend workflows
  • Excellent written English communication (B2+)
  • Comfortable experimenting with AI tools, coding agents, or automated code suggestions

Nice to have

  • Experience with Tailwind, Bootstrap, Material UI, Chakra, Radix, or similar UI libraries
  • Portfolio showcasing live projects, GitHub repos, design prototypes, or interactive demos
  • Prior experience in AI training, LLM evaluation, or annotation environments
  • Exposure to software testing, QA workflows, or documentation writing

What we offer

  • Remote, flexible work
  • Weekly payments upon approval
  • Opportunities for recurring project assignments
  • Experience collaborating with leading AI teams
