We are looking for a Competitive Data Scientist (Kaggle) with strong expertise in data science, machine learning, statistical modeling, and applied mathematics. The ideal candidate will have demonstrated experience participating in data science and machine learning competitions, such as Kaggle, DrivenData, or similar platforms.
In this role, you will use your competition experience, analytical thinking, and programming skills to design challenging, well-defined coding and data science tasks that require rigorous reasoning rather than plausible or superficial answers. You will build reproducible environments, develop verified reference solutions, and create robust evaluation mechanisms to assess the correctness and quality of AI-generated solutions.
This opportunity is ideal for individuals who enjoy solving complex technical problems,



experimenting with different approaches, debugging code, and evaluating the performance of AI coding systems.

Key Responsibilities
• Task Development: Design challenging data science, machine learning, and mathematical modeling tasks based on real-world problems and competitive programming experience.
• Workplace Setup: Build reproducible execution environments, prepare datasets, configure dependencies, and ensure consistent task execution.
• Reference Solutions: Implement accurate, efficient, and verifiable reference solutions for each task.
• Testing and Evaluation: Develop automated tests, validation criteria, and evaluation frameworks that distinguish correct solutions from incomplete, inefficient, or flawed implementations.
• AI Agent Evaluation: Run AI coding agents against designed tasks, analyze their performance, investigate failure patterns, and refine task specifications based on observed results.
