JavaScript Developer

Work from home Full-time role Hiring

JavaScript Developer (AI Training) About The Role What if your JavaScript expertise could directly shape how AI writes and understands code for millions of developers around the world? We're looking for experienced JavaScript developers to evaluate and improve AI-generated code — ensuring it's correct, efficient, and written to the standards real engineers expect. This is a fully remote, flexible contract role. No AI background needed — just deep JavaScript knowledge and a sharp eye for code quality.

  • Organization: Alignerr
  • Type: Hourly Contract
  • Location: Remote
  • Commitment: 10–40 hours/week

What You'll Do

  • Review and evaluate AI-generated JavaScript code for correctness, efficiency, and adherence to modern ES6+ standards
  • Write high-quality JavaScript solutions to problems spanning a range of difficulty levels
  • Craft clear, human-readable explanations of code logic and problem-solving approaches
  • Identify edge cases, bugs, and failure points in AI-generated web and backend code
  • Provide structured, actionable feedback that directly improves how AI models write and reason about code
  • Work independently and asynchronously — fully on your own schedule

Who You Are

  • Deep familiarity with core JavaScript concepts — async/await, closures, prototypal inheritance, DOM manipulation, and more
  • 3–5 years of hands-on experience with modern frameworks such as React, Node.js, or Vue
  • Comfortable writing clean, well-reasoned code and explaining your thinking clearly in writing
  • Naturally detail-oriented with a systematic approach to spotting what's wrong and why
  • Self-motivated and reliable when working independently without supervision
  • Bachelor's degree or higher in Computer Science or a related technical field preferred

Nice to Have

  • Experience with data labeling, RLHF, or other AI training or evaluation projects
  • Familiarity with TypeScript or other JavaScript-adjacent technologies
  • Background in code review, technical writing, or software quality assurance
  • Exposure to backend JavaScript environments and RESTful API development

Why Join Us

  • Work on cutting-edge AI projects alongside leading research labs
  • Fully remote and flexible — work when and where it suits you
  • Freelance autonomy with the structure of meaningful, task-based work
  • Make a direct, tangible impact on how AI understands and writes JavaScript
  • Potential for ongoing work and contract extension as new projects launch
