Data Science Internship, Summer 2027

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.

With over 500,000 customers who have utilized more than $1 billion in spending power, we are at a pivotal moment. We are scaling our operations, building new offerings, and deepening our impact. We are looking for teammates eager to join us on this journey.

Our venture partners include First Round Capital and L Catterton.

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.

Our 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.

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.

• 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.

What You’ll Bring:

• Currently enrolled in or will receive a Master's in Data Science, Computer Science, Computer Engineering, Information Systems, or an equivalent technical discipline with an expected graduation date between winter 2027 - summer 2028, or equivalent relevant experience.
• Knowledge of machine learning and statistical research.
