Responsibilities:

• Join an engineering organization filled with sharp engineers with a track record of building products used by millions
• Work with a squad of engineers to build high-quality Svelte Web Components that support white-label integration and can be fully customized through our theme editor, running reliably across desktop and mobile environments
• Collaborate closely with Product Design to extend and evolve our design system, ensuring components are consistent, scalable, and adaptable across partners and branding contexts
• Use modern tooling, including the latest AI, to think, build, and ship faster with less toil
• Help ensure the reliability and availability of the components you build, including participating in an on-call rotation with your squad
• Conceptualize and deliver front-end solutions with support and guidance from our Principal Engineers and Engineering Managers
• Become an emerging expert in modern web standards, Web Component architecture, front-end performance, accessibility, design-system-driven development, and scalable component patterns
• Spend the majority of your time building solutions rather than talking about them

Requirements:

• 6+ years of professional software development experience with strong TypeScript skills, solid HTML markup practices, and deep knowledge of CSS and accessibility, with experience across modern JavaScript frameworks such as Svelte, React, or Vue
• 4+ years of experience building embeddable UI components that partners can integrate independently without direct engineering coordination covering white labelling and accessibility
• 2+ years of experience building production-ready Web Components, including embedding components into third-party desktop or mobile application environments and understanding the constraints that come with externally hosted integration
• A bias towards action. You have a proven track record of delivering solutions in a fast-paced environment
• Meaningful experience contributing to design systems, including building reusable components, defining tokens, and managing shared state patterns across complex UI surfaces
• Experience with modern front-end tooling, build systems, component-driven architecture, and practical state management patterns that support predictable and maintainable UI behavior
• Experience consuming APIs backed by relational or document data sources, with a clear understanding of how frontend systems shape, model, and present that data
• A portfolio or collection of work that demonstrates strong frontend craftsmanship, component design, and attention to detail
