Frontend Engineer (Coding Agent Experience)

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 2–3 hours after ramp-up.

– 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.
