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 across a range of difficulty levels — from everyday utility functions to complex async logic
- Identify bugs, edge cases, and failure modes in AI-generated web and backend code

Candidate background
Who You Are
- Deep familiarity with core JavaScript concepts — async/await, closures, prototypal inheritance, DOM manipulation, and more
- 3+ years of hands-on experience with modern JavaScript frameworks such as React, Node.js, or Vue
- Strong instincts for clean, readable, maintainable code — you know the difference between code that works and code that's well written
- Naturally detail-oriented with a methodical approach to evaluating quality
- Able to articulate technical reasoning clearly in writing
- A degree in Computer Science or a related field is preferred, but demonstrated experience matters most
