Role Overview
As a Machine Learning Engineer, you will solve complex coding challenges to create "Golden Data" for training advanced code-generation models. You will likely engage in "red-teaming" (adversarial testing) to find logic gaps in AI code, write unit tests for generated snippets, and provide expert-level refactoring. This is pure technical work—no meetings, just deep-dive problem solving in languages like Python and C++.
Requirements
- Mercor is collaborating with a leading AI research lab to support the evaluation of advanced machine learning systems. We are seeking experienced machine learning engineers and researchers to contribute to the design of high-quality evaluation suites that measure AI performance on real-world machine learning engineering tasks. The work focuses on translating practical ML research and engineering workflows into structured benchmarks for frontier models. This is a project-based, remote opportunity suited for experts with hands-on ML research experience.
- Key responsibilities
- Design and write detailed evaluation suites for machine learning engineering tasks
- Assess AI-generated solutions across areas such as model training, debugging, optimization, and experimentation
- Ideal qualifications
- 3+ years of experience in machine learning engineering or applied ML research
- Must be eligible to work in Remote
Compensation Analysis
This role offers a powerful combination of high income ($110/hr) and total flexibility. Unlike traditional contracting, you generally set your own hours. It is an ideal "second stream" of income for professionals who want to stay sharp in their field while gaining exposure to the booming AI industry.

View All Mercor Jobs →Frequently Asked Questions
Is this for freelancers or full-time employees?
Both. Mercor tries to match you with clients who want long-term contractors. Unlike other platforms where you log in and grab small tasks, Mercor matches you with one company for a steady role (e.g., 'Python Tutor for 3 months').
I'm not comfortable on camera. Can I still apply?
No. The application requires a video interview with an AI avatar. The AI asks you questions about your resume, and the video is shared with potential clients to prove your communication skills.
Does it cost money to join?
No. You should never pay to join these platforms. Mercor makes money by charging the client a fee on top of your hourly rate.
Is this traditional consulting?
Not exactly. You act as a "Teacher" for advanced AI. Instead of client deliverables, you are given complex scenarios to evaluate. You grade the AI's logic, correct its hallucinations, and provide expert-level reasoning. Your job is to train the model to think like you do.
Why is the pay so high?
This role requires deep, verified expertise. General knowledge isn't enough; the model is specifically being trained on "edge cases"—the rare, difficult, or highly technical nuances that only a senior professional would know.
What is the workload like?
This is cognitive, deep work. Unlike simple data labeling, you might spend 45-60 minutes on a single task, researching citations or verifying complex calculations. Quality is prioritized over speed.
How soon will I start?
Important: Mercor is a talent marketplace, not a task queue. Applying puts you in a pool of candidates. You will only start working when a specific client (like a major AI lab) selects your profile. This matching process can take weeks.
