London, Greater London, United Kingdom Mercor Full time £42,240 - £70,560 per year

Role Overview

Mercor is partnering with a leading AI research lab on Project Vesuvius, an initiative designed to evaluate and enhance the ability of large language models (LLMs) to generate structured, high-quality research plans for open-ended machine learning problems.

We are seeking Machine Learning Researchers and PhDs to serve as annotators who will assess and provide structured feedback on AI-generated research plans. The goal is to improve how LLMs function as brainstorming partners for machine learning research.

This is a remote, short-term engagement with flexible hours and opportunities to contribute to frontier AI evaluation and research.

Key Responsibilities

  • Evaluate and compare AI-generated research plans for clarity, feasibility, and technical soundness.

  • Design and compile ML tasks based on real-world challenges and research competitions.

  • Draft detailed, executable natural language plans for machine learning workflows.

  • Implement and validate research plans in Python within a Docker environment.

  • Assess outputs against structured rubrics, provide usefulness scores, and deliver concise, objective feedback.

Ideal Qualifications

  • 5+ years of experience in applied machine learning or a PhD in machine learning or related fields.

  • Strong understanding of ML research methodologies, experimental design, and evaluation practices.

  • Excellent analytical and technical writing skills.

  • Experience with reproducibility or benchmarking in ML research preferred.

  • Detail-oriented and able to deliver high-quality, structured feedback independently.

Engagement Details

  • Type: Independent contractor

  • Mode: Fully remote and asynchronous — work from anywhere, on your own schedule.

  • Commitment: Maximum 80 hours per week

  • Project Name: Vesuvius

This role is designed for researchers and engineers who value autonomy, precision, and meaningful contribution to frontier AI development.

Compensation & Contract Terms

  • Hourly Pay Rate: Up to $140/hour

  • Payment: Weekly via Stripe Connect

  • Contract Type: Independent contractor engagement

  • Structure: Remote, milestone-based evaluation with flexible scheduling

  • Application Process

  • Submit your resume or CV highlighting relevant ML research or engineering experience.

  • Complete a short AI-based interview and a brief questionnaire about your experience with reproducibility and model benchmarking.

  • Selected candidates will receive detailed onboarding materials and access to the project environment.
