Frontend JavaScript Engineer
Frontend JavaScript Engineer (AI Training)
About The Role
What if your JavaScript expertise could directly influence how AI writes and understands code for millions of developers around the world? We're looking for experienced Frontend JavaScript Engineers to evaluate, critique, and improve AI-generated code — helping ensure the next generation of AI tools actually thinks like a great engineer.
This is a fully remote, flexible contract role. Training and onboarding support will be provided — no prior AI experience needed. Just bring your deep knowledge of JavaScript and a sharp eye for quality code.
• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week
What You'll Do
• Evaluate AI-generated JavaScript code for correctness, efficiency, and adherence to modern ES6+ standards
• Assess DOM manipulation approaches and identify performance issues or anti-patterns
• Solve complex UI/UX challenges to test the model's ability to produce responsive and interactive frontend solutions
• Identify bugs and suboptimal patterns in AI-generated frontend logic and provide clearly optimized alternatives
• Write human-readable documentation explaining state flow, event handling, and code structure
• Work independently and asynchronously — fully on your own schedule
Who You Are
• Deep, hands-on knowledge of core JavaScript concepts — async/await, closures, the event loop, and DOM manipulation
• 3–5 years of practical experience with modern frameworks such as React, Vue, or Node.js
• Strong instincts for clean, maintainable, and efficient frontend code
• Naturally detail-oriented with a systematic approach to evaluating and improving code quality
• Clear written communicator who can explain technical reasoning in plain terms
• Bachelor's degree 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 testing frameworks, code review workflows, or frontend performance profiling
• Background in technical writing or code documentation
Why Join Us
• Work on cutting-edge AI projects alongside leading AI research labs and teams
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based engineering work
• Make a direct, tangible impact on how AI understands and generates JavaScript code
• Potential for ongoing work and contract extension as new projects launch
