About Us: Perpay is a certified B Corp and Philadelphia’s most impactful growth‑stage startup. We are driven by a mission to significantly improve the financial stability of everyday Americans. For the past decade, we have established strong product‑market fit and a profitable, efficient operating model across a suite of products, positioning Perpay as the premier financial partner for consumers with subprime credit.

Products we’ve built to make an impact:

• Perpay Marketplace: Combines interest‑free payments and modern e‑commerce to reduce cost of ownership and promote healthy repayment behavior.
• Perpay+: Leverages Marketplace repayment history to help members monitor and build credit with all 3 credit bureaus.
• Perpay Credit Card: Expands access to the flexibility and benefits of a World Mastercard by removing common barriers like high security deposits and low approval odds.

The team thrives on in‑person collaboration, operating from our unique center‑city Philadelphia office. This comfortable "home away from home" space offers river views and fosters rapid product development, strong relationships, and career growth. The energy from achieving big wins is palpable here. While we primarily work in the office, we offer sensible flexibility for personal needs, such as sick children or urgent errands, and coordinate official remote weeks around major holidays. If you are passionate about a meaningful mission, collaboration, equity, and generous perks, Perpay is the best place to be in Philadelphia right now.

This is a Super Day Hiring Event specific job posting.

What is Super Day?

It’s an accelerated hiring event that will give you the unique opportunity to land this role in just one day! We will host it on November 13th at Perpay HQ in Philadelphia. Selected candidates will tour the office, meet the team, and experience a fast‑tracked interview process. Attendance is invite‑only, and applicants must complete a pre‑work challenge to be considered.

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.
