Location: Remote · Type: Independent contractor · Hours: Flexible hours · Payouts: Weekly

Overview

Models are surprisingly bad at reasoning about themselves: training dynamics, evaluation design, data pipelines, and deployment trade-offs. Plausible-sounding ML advice is often subtly wrong.

As a Machine Learning Engineer you'll stress-test how models reason about ML systems and write the answers a strong practitioner would give, shaping how the next generation handles your field.

What you’ll actually do

  • Write prompts that probe how models reason about training, evaluation, debugging, and productionizing ML systems.
  • Review AI output for subtle errors: leaky evaluations, wrong loss formulations, and misdiagnosed training failures.
  • Write the correct solution when the model falls short, grounded in real practitioner experience.

Roles this fits

Common backgrounds: ML Engineer, MLOps Engineer, Applied Scientist.

What we look for

  • Hands-on experience training, evaluating, or deploying models professionally or in serious personal work.
  • Comfort with the modern ML stack; most tasks assume Python and PyTorch or JAX.
  • Clear written English: your explanations are the training signal.
  • No degree required. We care about what you can do, not where you learned it.

Compensation

Up to $40 – $150+/hr depending on task difficulty and specialization. Many contributors add $10k–$100k+ a year; some make it their full-time income.

About DataAnnotation

DataAnnotation is where 100k+ experts train the world’s leading AI models. $150M+ paid to contributors to date, and the average contributor stays 5+ years. Flexible, remote, and always project-available.

How it works

Apply, pass the qualification assessment, then pick up paid projects whenever you want and get paid weekly.
