Software Engineer - Frontend

Software Engineer – Frontend (AI Training Contract)
About The Role
Frontend developers: your skills are in high demand — not for a product sprint, but to help train the next generation of AI. We're looking for experienced frontend engineers to evaluate, write, and refine high-quality UI coding problems and solutions that directly improve how AI models understand and generate frontend code.
This is a fully remote, flexible contract engagement. Work asynchronously on your own schedule, and make a real impact on the AI systems used by leading research labs and enterprise teams worldwide.
What You'll Do
Review and evaluate AI-generated frontend code (JavaScript, HTML, CSS) for correctness, efficiency, accessibility, and best practices
Write high-quality frontend solutions to UI and web development challenges across a range of difficulty levels
Craft clear, well-reasoned explanations for design decisions, code logic, and problem-solving approaches
Identify edge cases, ambiguities, or errors in problem statements and AI-generated responses
Help set the standard for what great frontend code looks like — for both humans and AI
Who You Are
Fluent in English with strong written communication skills — you can explain complex frontend concepts clearly and concisely
Deep expertise in JavaScript, including async/await, closures, DOM manipulation, ES6+ syntax, and browser APIs
Experienced with modern frontend frameworks and tools such as React, Vue, or Angular
3+ years of hands-on frontend or web development experience preferred
Bachelor's degree (or in progress) in Computer Science or a related field — Master's or PhD is a plus, but not required
Detail-oriented and comfortable working independently without close supervision
Nice to Have
Familiarity with accessibility standards (WCAG) and performance optimization techniques
Experience with state management libraries (Redux, Zustand, Pinia, etc.)
Prior work on data labeling, RLHF, or AI model training projects
Why This Role
High impact — your expertise directly influences AI models trusted by top labs and Fortune 500 companies
Full autonomy — work remotely and asynchronously, on a schedule that works for you
Clear ownership — defined tasks with measurable outcomes, no ambiguity about what success looks like
Growth opportunity — top contributors take on expanded responsibilities and mentor incoming subject matter experts
Meaningful work — help ensure AI writes better, safer, and more reliable frontend code
