Schedule: Flexible-you choose the hours and days you work, including weekends if desired

We're looking for data scientists, machine learning practitioners, and applied mathematics experts with competitve Data Science experience. (Kaggle, DrivenData, etc.)

You’ll draw on your competition experience, mathematical reasoning, and programming skills to create tasks that require more than a plausible answer. Each task should have a reproducible environment, a verified reference solution, and reliable checks for successful completion.

Required Skills

ML Engineering

Data Science

Mathematics

Coding

What You’ll Do

Build reproducible environments, prepare relevant data and dependencies, and implement reference solutions.

Develop tests and evaluation criteria that reliably distinguish correct solutions from incomplete or flawed approaches.

Run coding agents against tasks, investigate their failures, and refine the tasks based on observed behavior.

Identify implementation errors, flawed assumptions, data leakage, and other issues that affect correctness.
