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.

• Contribute to the Engineering design process by bringing forward tradeoffs and opinions.

What You’ll Bring

• Minimum of 2 years experience as a Software Engineer (excluding internships or co‑op experiences) with a focus on full‑stack development.
• Strong proficiency in at least one backend application framework such as Django or Flask and experience with frontend technologies such as React, Angular, or Vue.js.
• Proven experience building, deploying and maintaining scalable web applications, with knowledge of database design and management.
• Knowledge of RESTful API design and integration.

• Passion for learning new technologies and keeping up with industry trends.
• Ability to collaborate with cross‑functional teams, including UX designers, product managers, and other Engineers.
• Strong communication skills and ability to articulate technical concepts to non‑technical stakeholders.

What We’ll Bring to Full‑time Team Members

• Meaningful compensation and equity.
• Premium medical benefits (fully paid base plan, and very reasonable premium for the buy‑up option).
• 4% employer 401k match.
• Unlimited PTO policy.
• Remote weeks around major holidays and extra holiday on weekends like MDW and LDW.
• High‑quality catered lunch by local chefs, 4 days / week.
