More about the Machine Learning Engineer (Coding Agent Experience) role at Mercor

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 machine learning engineering workflows and model evaluation. 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 machine learning and AI engineering tasks. Review model-generated implementations involving model training, inference systems, MLOps, and LLM applications. Identify bugs, edge cases, performance issues, and failure modes. Compare outputs from multiple frontier models and assess their strengths and weaknesses. Apply professional engineering judgment to realistic ML 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
