Machine Learning Applied Scientist, Part-Time AI Task Evaluation - Remote (United States)

• $60–$120 per hour equivalent, paid per accepted task

• 100% remote

• Part-time

• About 15 hours a week, you choose when

Use your machine learning expertise to help shape frontier AI, on a schedule that fits around your work.

The AI models everyone is talking about are trained and tested by experienced machine learning scientists. The teams developing them need experts who can design realistic, demanding engineering tasks, assess the answers AI produces, write the solution a specialist would give, and show precisely what the result gets wrong. Your judgment helps shape the next generation of AI models. You can do this work remotely around your current job.

What you'll do

• Design realistic machine-learning tasks around model development and training pipelines

• Assess AI-written implementations for correctness and performance

• Produce reference implementations and repeatable Python-based validation workflows

• Debug failures at the numerical or system level and explain what the solution gets wrong

Why this is worth your time

• Get paid the equivalent of $60–$120 an hour to build real AI skills, on top of your current job

• Work directly with frontier AI and machine-learning tools, seeing how teams build, test and improve them—experience most machine learning scientists will not have for years

• Build a career edge for what comes next: AI is reshaping machine learning, and the people who understand it from the inside will lead that change

• Fully remote, fully flexible, no minimum shift, no commute

Who this is for

• Graduate training at the master's or PhD level in computer science, machine learning, artificial intelligence, applied mathematics, statistics, engineering, or another closely related quantitative field

• Strong experience from professional or research work in machine learning, together with practical Python proficiency

• Fluent in English

• No experience in AI training work needed. You bring the expertise; your judgment helps improve AI models.

Pay and details

• $60–$120 per hour equivalent; pay is per accepted task, as an independent contractor
