Job description

• 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


• 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


• 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

Benefits

• Competitive salaries, equity, and a 401(k) plan


• Top-of-the-line healthcare (medical, vision, and dental), with 100% primary coverage and 75% dependent coverage for medical


• Unlimited paid time off, with a minimum of 15 days off per year


• Parental leave for birthing and non-birthing parents


• Team trips & offsites


• For in-office employees:


• Catered lunch at the office every day, plus plenty of snacks & drinks


• $250/month commuter assistance for public transit or our parking garage


• For remote employees:


• $500 remote setup stipend to help you do your best work
