Cardless is building the infrastructure for the world's best companies to design, build, and launch financial products of their own. Companies like Coinbase and Bilt use Cardless to create credit cards that feel entirely their own. In an industry where branded financial products usually mean shared logos and shared control, Cardless is built to disappear. Our APIs and components shape the journey from the first application to every purchase, reward, and moment of support that follows, while we handle lending, compliance, and operations behind the scenes.
In September 2025, we raised a $60 million Series C led by Spark Capital, bringing our total funding to $170 million. The team is over 70 people and scaling toward profitability by year-end 2026.
We're looking for kind, humble people with high standards and low egos. We take the work seriously without taking ourselves too seriously. We see what could be improved, make it so, and leave every product, system, and team better than we found it.
We're looking for an experienced full stack engineer to help build and shape the experiences that power our co-branded credit card platform — used by hundreds of thousands of cardholders every day.
This role sits at the center of nearly everything user-facing at Cardless: the component library and design system that everything else is built on, the consumer app cardholders use to manage their accounts and rewards, and the internal tools our operations and risk teams rely on to run the business. You won't just maintain these experiences — you'll set the patterns and architecture that keep them consistent, scalable, and high-quality as the company grows, while also shipping real features in each of them yourself.
This is a strong fit for someone who can move fluidly across consumer, partner-facing, and internal tooling work without compromising on craft — someone who cares as much about the accessibility and reusability of a design system component as they do about the polish of a cardholder-facing onboarding flow. You'll partner closely with product, design, backend engineering, and our risk and compliance teams, and you'll have real influence over how Cardless's frontend platform evolves.
Own and evolve our component library and design system: build scalable, reusable components and establish the patterns that keep our consumer app, partner-facing UIs, and internal tools consistent and high-quality

Drive improvements in performance, accessibility, observability, and developer experience across the stack
Contribute to architectural decisions that shape the evolution of our frontend platform
Provide technical guidance to peers across engineering
5+ years of frontend engineering experience building production systems at scale, including 3+ years with React across consumer products and data-heavy internal tools
Strong fundamentals in state management, component architecture, accessibility, testing, and UI quality, with familiarity with experimentation and personalization systems a plus
Experience building and maintaining component libraries or design systems used across multiple products, with an eye for usability, scalability, and maintainability
Ability to move across consumer, partner, and internal surfaces without compromising on craft or user experience
Proven track record of delivering complex projects end-to-end in cross-functional environments
Clear communicator who learns quickly and teaches others just as well
Comfortable in fast-moving, ambiguous environments with competing priorities and deadlines
Experience in fintech, payments, fraud, or financial services
Familiarity with micro-frontend architectures or component library development
Familiarity with Next.js , TailwindCSS, React Native, Yarn monorepos
Working knowledge of API design and backend integration patterns (REST/GraphQL) to collaborate effectively with backend teams
