Located in Center City, Philadelphia, our one-of-a-kind space promotes a collaborative work environment, unites our team, and feels like a home away from home. As a certified B Corp, Perpay is committed to building a mission-driven culture that balances purpose and performance - Learn more.

Some things we’re excited about:

  • $500 million in spending power used by our members
  • Increasing members’ credit by 32 points (on average) within the first 3 months
  • Backed by First Round Capital and JP Morgan

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.

 

About the Role:

We are looking for experienced Mid-level Full Stack Engineers passionate about building an excellent user experience up and down the layers of an application. The ideal candidate has contributed to features on at least one sizable production application using modern frameworks within the past year. An experienced Mid-level Full Stack Engineer at Perpay will spend their time writing code, reviewing PRs, and helping scope & design new features. We value Engineers who demonstrate excitement around solving tough problems and delivering solutions in a fast-paced environment. We aim for our Engineering team to be a place that Mid-level Engineers can push our quick-growing startup forward, and can grow into future Senior Engineers and Engineering leaders. The significant projects and initiatives available to our Mid-level Engineers provide opportunities to expand experience, ownership, and business value.

Much of our team is full stack, so we look for team members excited to learn new technologies and work across all stacks, even if it’s not something you’ve done before! Our tech stack: Javascript, React, React Native, Redux, Python, Django, Flask, Kubernetes, AWS, Docker and more.

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

 

Responsibilities:
  • Collaborate closely with the development team, including UX designers, product managers, and other Engineers, to implement solutions that meet business needs and provide the best user experience
  • Work with stakeholders to design, build, test, and release new features for our platform
  • Write clean, efficient, and maintainable code. Break down code contributions into reviewable, shippable chunks
  • Contribute to the Engineering design process by bringing forward tradeoffs and opinions
  • Identify opportunities to reduce technical debt and implement changes to improve developer experience and team velocity
  • Participate independently in on-call rotation and coordinate incident response

 

What You’ll Bring:
  • Minimum of 5 years experience as a Software Engineer (excluding internships or coop 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
  • Experience working with cloud infrastructure and containerization technologies such as AWS, Docker, and Kubernetes is preferred
  • 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

Hey, we know not everybody checks all the boxes, so if you’re interested, please apply because you could be just what we’re looking for!

  What We’ll Bring:
  • Competitive salary + company equity
  • 401k with company match
  • Medical / Dental / Vision insurance
  • Flexible Spending Account (FSA)
  • Team member discounts 
  • Relocation assistance
  • Pre-tax commuter benefit
  • Student loan repayment match
  • Gym subsidy with City Fitness
  • Cell phone plan
  • Paid parental leave
  • Unlimited PTO

 

Additional Perks:
  • Opportunity to gain experience at one of the fastest-growing financial startups in the country
  • Work on both e-commerce & fintech customer-facing products
  • Collaborate cross-functionally with product, design, marketing, operations, data teams, and more

 

This is not a remote opportunity; it is 100% onsite (#LI-Onsite) (#LI-TH1) (#LI-AK1)

Perpay is proud to be an equal opportunity employer. We value diversity in all its forms and are committed to creating an inclusive environment. We do not discriminate on the basis of race, religion, color, national origin, gender identity, sexual orientation, sex (including pregnancy), marital status, political affiliation, age, veteran status, disability status or other non-merit factor.
