• Code Quality: a high standard for clean code, including modularity, readability, and adherence to modern ES6+ standards.
• Attention to Detail: ability to spot subtle logical flaws, memory leaks, or security vulnerabilities (e.g., XSS, prototype pollution) in model-generated code.

What you'll be doing in the role

• Validate Logic & Reasoning: audit the step-by-step explanations provided by AI for complex algorithmic solutions to ensure they are logically sound.
• Annotate Model Performance: identify areas where a model provides inefficient solutions, deprecated syntax, or hallucinated library methods.
• Refine Technical Logic: provide structured feedback on how models reason through frontend or backend architecture discussions.

• Frameworks: extensive experience with React
  , Node.js
  , Vue
  , or Angular
  .
• Testing & Tools: proficiency with Jest
  , Cypress
  , Webpack
  , and Vite
