About the Role

Our data team is organized across three groups: Data Engineering, Data Science, and Strategic Analytics. Data Science owns the modeling work that drives Perpay's most consequential decisions: credit decisioning, loss forecasting, marketing-mix attribution, product experimentation, and the ML systems that sit in front of our customers in real time.

As a Data Science intern, your main responsibility is to learn, but you'll learn it by doing real work. During the summer of 2027, you'll leverage our expansive data sets to research, identify, and build features to train models and drive real impact. Applying your knowledge of modeling, statistical methodologies, and exploratory data analysis, you'll partner with stakeholders across Engineering, Risk, Marketing, Merchandising, and Finance and communicate solutions designed to drive company growth, getting hands-on with our stack, which includes Python (scikit-learn, pandas, NumPy, statsmodels), SQL, and Redshift.

Our greatest strength is our people, and we’d love for you to be one of them!

What to Expect from the Internship

Within your first week, you'll

Introduce yourself on Slack and meet your team.

Get oriented in our data sets, walk through existing models and analyses with the rest of the team, and read enough of the codebase to start asking useful questions.

Within your first month, you'll

Get fluent enough in our data sets and modeling tools to explore and build independently.

Scope your first real project with a mentor, including the modeling or statistical approach and the trade-offs involved.

Ship your first contribution. It could be a feature, an analysis, or a small improvement to an existing model.

By the end of your internship, you'll

Have shipped a model, feature, or analysis that the team relies on after you're gone.

Have presented your work to the broader team, and walked away with a real sense of what production data science looks like day to day.

Have met with various business owners across the company to build your network and get a feel for how a data team fits into a fast-paced startup.
