Lead Svelte Software Engineer

Array is a financial innovation platform that helps digital brands, financial institutions, and fintechs get compelling consumer products to market faster. The Lead Svelte Software Engineer will play a key role in shaping and elevating the front-end engineering practice, focusing on delivering high-quality, scalable implementations and driving technical influence across teams.

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
• Strong proficiency in TypeScript, HTML, and CSS, including accessibility best practices
• Experience building applications with modern JavaScript frameworks such as Svelte, React, or Vue
• Experience developing mobile applications using Kotlin and/or Swift
• 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
