Applied Scientist, Part-Time AI Model Evaluation - Remote (United States)

• $245–$280 per hour

• 100% remote

• Part-time

• Fully flexible schedule

Work on the cutting edge of AI, on your own schedule, and get paid for the statistics and machine learning skills you already have.

The AI models everyone is talking about are trained and tested by real experts. The companies building them need applied scientists who can pose realistic, hard statistics and machine learning problems and judge how well the AI works through them. They also need those experts to produce the analysis a seasoned practitioner would deliver and to explain exactly where the AI’s reasoning breaks down. Your judgment becomes part of how the next generation of AI models handles data and numbers. This is that work, done remotely, around your current job.

What you’ll do

• Write challenging statistics and machine learning problems, along with the datasets that go with them

• Review AI-generated answers and judge whether the analysis and the modeling actually hold up

• Build the reference solutions as reproducible Python code with a clear write-up of methods and findings

• Pinpoint where the AI went wrong, from flawed methods to statistical errors, and give structured feedback on each case

Why this is worth your time

• Get paid $245–$280 an hour to build real AI skills, on top of your current job

• Work directly with frontier AI tools and see how they are built, tested and improved, experience most people in data science will not have for years

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

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

Who this is for

• Practical expertise in Python, including Pandas and scikit-learn

• Hands-on experience developing, tuning and evaluating machine learning models, grounded in applied statistics and experimental design

• Fluent English and clear written and spoken communication, including the ability to explain your technical decisions

• No experience in AI training work needed. You bring the expertise; we bring the training on the tools.
