Competitive Data 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

Work on the cutting edge of AI, on your own schedule, and get paid for the data science expertise you already have.

The AI systems everyone is talking about are trained and tested by real data scientists. The teams building them need people who can create realistic, difficult data science tasks, judge how well an AI solution works, write the solution a professional would give, and explain exactly where the AI falls short. Your judgment becomes part of how the next generation of AI models handles quantitative work and code. This is that work, done remotely, around your current job.

What you’ll do

• Build reproducible data science tasks with clear requirements, data, dependencies and execution steps

• Run AI coding agents against those tasks and judge whether their solutions are genuinely correct

• Write verified reference solutions and tests that distinguish complete work from flawed approaches

• Investigate failures, including data leakage and flawed assumptions, and improve the task design

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 tools and see how they are built, tested and improved, experience most data scientists will not have for years

• Build a career edge for what comes next: AI is reshaping data science, 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

• Practical data science and competition experience, such as work with Kaggle, DrivenData, Zindi, AIcrowd, Numerai, DataSource.ai or CodaLab/Codabench

• Strong Python skills, including testing, debugging and working with unfamiliar code

• Fluent English

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

Pay and details

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

• About 15 hours a week, you choose when; fully remote, United States
