Data Science Intern

As a Data Science Intern, you will do real data science work in support of our mission to discover, inspire, and train the great problem solvers of the next generation. Paired with a data scientist mentor, you will frame questions, build and evaluate models, analyze experiments, and present findings to the teams who act on them.
We hire for data sense, not a specific major. Strong data scientists come from economics, psychology, education, linguistics, and the humanities as well as math and computer science. What matters is that you can work with data in SQL and Python, reason carefully about what it does and does not tell you, and explain what you found.
The Data Science Intern will:
Own a scoped data science project from question to recommendation under the guidance of experienced data scientists
Use SQL and Python to gather, clean, explore, and validate data
Build and evaluate statistical and machine learning models, with attention to their assumptions and limitations
Analyze and separate real effects from noise and bias
Write reproducible, documented code and participate in code reviews
Present findings to the Data team and to stakeholders through clear visualizations and recommendations
Use AI tools to accelerate your work while critically evaluating their output
Complete other tasks and responsibilities, as assigned
The ideal candidate has:
A bachelor's or graduate degree in progress in any field
Hands-on experience using Python (e.g. pandas, polars, scikit-learn, matplotlib) and SQL to work with data, through coursework, research, or personal projects
Experience in statistics, including hypothesis testing and regression
Strong data sense: you ask where data came from, what it leaves out, and whether it actually answers the question
Strong written and verbal communication skills, including the ability to explain technical results to non-technical audiences and to give and receive constructive feedback

About AoPS:
Art of Problem Solving (AoPS) is on a mission to discover, inspire, and train the great problem solvers of the next generation. Since 2003, we have trained hundreds of thousands of the country’s top students, including nearly all the members of the US International Math Olympiad team, through our online school, in-person academies, textbooks, and online learning systems. While our primary focus has been math for most of our history, through the years we have expanded our unique problem solving curriculum into more subjects, such as language arts, science, and computer science.
