About the UI Platform teams

Design System

This team owns Stripe’s design system, and therefore plays a critical role in the creation of intuitive and high-quality user experiences at Stripe. We are responsible for delivering essential UI components, infrastructure, and best practices that ensure consistency and excellence across all product surfaces. Our platform supports a diverse range of applications—from extensive web platforms to embedded interfaces and SEO-optimized sites—empowering product teams to rapidly build and deploy with confidence. By focusing on consistent interactions, accessibility, and performance, we provide seamless and engaging user interactions.

Core UI

The Core UI team provides essential front-end APIs, primitives, and tools that empower Stripe teams to build user interfaces at scale, efficiently, and with consistency. We focus on foundational building blocks such as data fetching, navigation, observability, feature flagging, and testing utilities. By addressing complex, low-level challenges, we aim to enhance the performance of our web applications and create a seamless development experience for our fellow engineers at Stripe. Our team is ambitious and forward-thinking, committed to building solutions that not only meet today's needs but also lay the groundwork for future innovations, ultimately enriching the value that Stripe can deliver to its customers.

UI Extensibility

The UI Extensibility team builds on the foundation established by Core UI and Design Systems to create powerful frontend tooling for both first and third-party developers. We specialize in developing the framework that enables developers to extend Stripe surfaces and the products of our Connect customers through UI Extensions in Stripe Apps. Our team is responsible for building and maintaining the UI extension SDK, managing the in-browser lifecycle of apps through our runtime environment, and providing all the necessary infrastructure to develop, run, and present these extensions to users. In short, UI extensibility aims to empower developers to build seamlessly integrated, customized business solutions that work across the Stripe ecosystem.

About Stripe Barcelona

This is an exciting opportunity to join the team as we build up our presence in Barcelona. Please be aware that this role currently requires you to come to the office once a week. In the near future, the work model will shift to a hybrid arrangement, with a 50% remote and 50% in-office presence in Barcelona, Spain.

• Develop and execute against both short and long term roadmaps to evolve Stripe’s UI platform
• Contribute to the overall software architecture of Stripe UI products
• Build internal tooling and process to support developers building on our platform
• Make effective tradeoffs that consider business priorities, user experience, and a sustainable technical foundation
• Engage in troubleshooting, debugging, and optimizing components and frontend APIs to ensure reliable and efficient user interface delivery

Who you are

We’re looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Minimum requirements

• Residence in the Barcelona metropolitan area, or willing to relocate.
• 4+ years of industry front-end development experience, building, running, and debugging web applications using modern JS frameworks (e.g., React, Vue, Angular).
• Advanced knowledge of modern HTML and CSS
• Familiarity with building and maintaining frontend components or libraries.
• Experience with frontend build tools, module bundlers, package managers, and codemods.
• Strong problem-solving skills and ability to debug frontend issues.

• Appreciation for the importance of good documentation -- internal and external.

Working remotely at Stripe

A remote location, in most cases, is defined as being 35 miles (56 kilometers) or more from one of our offices. While you would be welcome to come into the office for team/business meetings, on-sites, meet-ups, and events, our expectation is you would regularly work from home rather than a Stripe office. Stripe does not cover the cost of relocating to a remote location. We encourage you to apply for roles that match the location where you currently or plan to live.

This salary range may be inclusive of several career levels at Stripe and will be narrowed during the interview process based on a number of factors, including the candidate’s experience, qualifications, and specific location. Applicants interested in this role and who are not located in the primary location may request the annual salary range for their location during the interview process.

Specific benefits and details about what compensation is included in the salary range listed above will vary depending on the applicant’s location and can be discussed in more detail during the interview process. Benefits/additional compensation for this role may include: equity, company bonus or sales commissions/bonuses; retirement plans; health benefits; and wellness stipends.
