Senior Design Engineer II

Senior Design Engineer II Kit https://kit.com/ is an email-first operating system for creators who mean business. We help creators grow and monetize their audience with ease. For coaches, YouTubers, authors, podcasters, and other creatives, there isn't a better marketing hub to rely on to grow audiences, automate email marketing, and sell digital products — all within one platform. More importantly, there isn't a team more committed to helping creators earn a living. We're on a mission to help creators earn $1 billion using our creator marketing platform. We have always been 100% independent and 100% remote. We are proud to have built a product that our customers love, and we look for people who have enthusiasm and belief in our mission, vision, and values to join our team. We're also embracing AI thoughtfully — both in how we build and how we hire to ensure our team is adaptable, innovative, and ready for what's next. THE ROLE Kit’s product surfaces have grown faster than the systems that keep them consistent. We need someone to close that gap. We’re looking for a Senior Design Engineer with strong hands-on experience in both product design and React to build and evolve our design system, raise UI quality across the app, and serve as the design-system decision maker at the intersection of design and front-end engineering. This is not a traditional frontend engineering role. You will be expected to make independent visual and interaction design decisions, not just implement specifications. The right candidate will be equally comfortable building in Figma as they are in React. This role is about building durable systems that raise product-wide quality, reduce rework for every feature squad, decreases time-to-ship, improves our customer journeys, and helps designers experiment with shipping to production. You'll work closely with our front-end engineering team to help lead the development and maintenance of shared foundations such as Storybook, React components, design tokens, and the design-to-code workflow. This is a full-time senior IC role ideal for someone who thrives at the intersection of design and code, enjoys systems thinking, and is excited to create the foundations that feature teams rely on to ship high-quality UI faster. The work you do will directly shape the experience creators have every time they use Kit YOUR SUPPORT SYSTEM You'll sit within the Product Design team and collaborate closely with Engineering, Product, and feature squads across Kit. You'll report to Dan Winer https://www.linkedin.com/in/danwiner/, our Director of Product Design, and partner directly with front-end engineers, product designers, and the feature project leaders who'll rely on the system you build. You'll also work alongside product managers when new features require new or evolved components. WHAT YOU'LL DO - First Week: Immerse yourself in Kit's product surfaces and current component landscape. Attend Get-To-Know-You (GTKY) meetings with Product Design and Engineering. Get access to Figma, our codebase, and understand the current state of UI consistency challenges. - First Month: Audit the current UI for patterns, tokens, and inconsistencies. Present your observations, help establish the token architecture mapped between Figma and code, and start implementing some missing components in React. - First Six Months: Establish tokens and primitives mapped between Figma and code in partnership with the front-end engineering team. Lead the development of 5-8 core components at production quality with full documentation (including the navigation component suite with performance targets). Work with designers to define pattern standards and begin providing React hand-offs for new feature work. Measurably improve layout consistency across key surfaces. Help the product design team use AI to experiment with shipping their designs to production — for example, using AI-assisted code generation to turn Figma work into functional compo ...
