Frontend Engineer (Coding Agent Experience) (Train AI Models Part Time!)

hackajob is collaborating with Mercor to connect them with exceptional professionals for this role. About the Role** - Mercor is partnering with a leading AI research lab to support a Frontier Code Agents project. - Contributors help evaluate and improve frontier AI coding models through structured technical assessments. - The work focuses on realistic frontend engineering workflows and model evaluation rather than traditional software development. - Spots are limited and filling quickly on a first come, first serve basis. What You'll Do - Use frontier AI coding agents to complete and evaluate complex engineering tasks. - Review model-generated frontend code for correctness, quality, maintainability, accessibility, and performance. - Identify bugs, edge cases, and failure modes in model outputs. - Compare outputs from multiple frontier models and assess their strengths and weaknesses. - Apply professional engineering judgment to realistic frontend engineering scenarios. Time Commitment - Sprint based project that runs in 12-24 hour stretches based on client requirement. Compensation - $400 per accepted task. - Typical tasks take approximately 1–3 hours after ramp-up. - No fixed task limits. - Compensation is tied to accepted work. Who Should Apply - 2+ years of professional frontend engineering experience. - Experience building modern web applications using React, TypeScript, JavaScript, or similar technologies. - Regular use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools. - Ability to evaluate model-generated frontend implementations, UI architecture, and performance optimizations. - Experience working on large-scale consumer or enterprise applications is preferred.
