About the role

Experienced full-stack engineer to build and shape the frontend experiences for Cardless’ co-branded credit card platform, including component library/design system, consumer app, and internal tools; focus on scalable, accessible, high-quality frontend architecture with end-to-end ownership.

Responsibilities

  • 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
  • Build and ship features in our consumer app, from cardholder onboarding through account management and rewards
  • Design and build internal tools that give operations and risk teams the workflows and visibility they need to run the business
  • Take projects from concept to production: requirements, implementation, testing, deployment, and maintenance
  • Partner closely with product, design, backend engineering, partners, risk, and compliance to deliver quickly and reliably
  • 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

Qualifications

  • 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
