Frontend JavaScript Engineer

We're looking for experienced Frontend JavaScript Engineers to evaluate, critique, and improve AI-generated code, ensuring AI tools think like a great engineer. This is a fully remote, flexible contract role with training provided.

• 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

• 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

• 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
