What are the key skills and qualifications needed to thrive in the software engineer startup position, and why are they important?

To thrive as a Software Engineer in a startup environment, you need solid programming skills, a problem-solving mindset, and a degree in computer science or related experience. Familiarity with agile methodologies, cloud platforms, version control (like Git), and rapid prototyping tools is highly valued, and startup engineers may also benefit from exposure to full-stack development. Adaptability, effective communication, and the ability to work independently in uncertain environments are standout soft skills. These competencies enable engineers to rapidly iterate on products, effectively collaborate across small teams, and contribute to the dynamic demands of a growing company.

What is a software engineer startup?

A Software Engineer Startup job involves developing, testing, and maintaining software in a fast-paced, early-stage company. Engineers in startups often wear multiple hats, working on both backend and frontend development, infrastructure, and sometimes even product decisions. The role requires adaptability, problem-solving skills, and the ability to work with limited resources. Unlike larger companies, startup engineers may need to prototype quickly, iterate based on user feedback, and contribute to the overall growth strategy. This position is ideal for those who enjoy dynamic environments and taking ownership of projects.

What can I expect from the daily work environment as a software engineer at a startup?

Working as a Software Engineer at a startup typically means you'll be part of a small, agile team where roles and responsibilities can shift quickly based on company needs. You'll often participate in daily stand-ups, collaborate closely with founders or product leads, and have the opportunity to contribute ideas beyond your core coding tasks. The pace is usually fast, and you'll likely wear multiple hats, working on everything from prototyping new features to troubleshooting production issues. This hands-on, collaborative atmosphere provides excellent opportunities for skill growth, creative problem-solving, and making a visible impact on the company's direction.

Job description

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:
We are looking for senior frontend engineers passionate about frontend technology and excellent user experience. The ideal candidate has helped lead the technical design and implementation of frontend features on at least one sizable production application within the past year. A senior frontend engineer at Perpay will spend their time writing code, reviewing PRs, mentoring engineers, and helping scope & design new features. We are looking for people who can bring frontend technical expertise to push our technology forward - whether it's hosting a lunch-and-learn on a new frontend technology or directing a large refactor. We value engineers who demonstrate excitement around solving tough problems and delivering solutions in a fast-paced environment.
Much of our team is fullstack, 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 and communicate with other members of the development team, including UX designers, product managers, and other engineers, to ensure that the frontend meets the needs of the business and provides an excellent user experience
  • Ensure our application is responsive and accessible across different devices and platforms
  • Write clean, efficient, and maintainable code
  • Contribute to the engineering design process by bringing forward tradeoffs and opinions on how to weigh them
  • Leverage continued research around the changing frontend landscape to bring best practices and innovation to our code, developer experience, and user experience

What You'll Bring:
  • 5+ years of experience delivering commercial products to market
  • 2+ years of experience leading technical teams and large, complex projects
  • Significant experience with React and the React ecosystem and unidirectional data flow patterns, preferably Redux
  • Strong knowledge of JavaScript, including the latest ECMAScript standards
  • Understanding of RESTful APIs
  • Experience with optimizing web applications for performance and accessibility
  • Product focus and a passion for UX/UI design or familiarity with UX/UI principles
  • Strong curiosity about industry trends
  • Ability to pick up new technologies quickly, with software engineering best practices prioritized over familiarity with specific tools or languages
  • History of cross-functional collaboration on mission-critical projects
  • Experience with React Native, AWS, Docker, and Kubernetes is nice to have
  • Experience standing up a design system is also a nice to have

NYC-level total cash-comp (base $160k into the $200's, plus equity and a discretionary cash bonus)
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 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 + extra holiday on weekends like MDW and LDW
  • High quality catered lunch by local chefs, 4 days / week
  • Gym subsidy
  • Paid cell phone + plan
  • Student loan repayment program
  • Relocation assistance
  • Generous team member discounts

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.
