Role
Who you are
- Strong visual design craft: typography, layout, spacing, color, and hierarchy
- Strong React/Typescript fundamentals and component architecture
- Design token architecture and Figma-to-code mapping
- Building and maintaining Storybook for component development
- Deep understanding of interaction design, states, and edge cases
- The ability to spot and resolve visual and interaction inconsistencies across a product surface — not just in isolation, but in context
- Performance and accessibility standards
- Systems thinking and building for scale
- Clear documentation and pattern guidance
- Ability to validate technical feasibility early in the design process
- 6+ years of relevant experience with meaningful design system work as a significant part of that — building, scaling, and maintaining a design system in production
- Proven track record retrofitting and modernizing legacy UI systems, migrating inconsistent patterns into cohesive design systems
- Prior experience working as a designer
- Portfolio demonstrating effective use of UI design fundamentals
- Deep experience with composition and presentational component architecture in React
- Proven track record maintaining Storybook as a canonical UI reference
- Built and managed design token systems with Figma integration
- Evidence of successfully bridging design and code in a live product
- Experience collaborating with product designers and engineering teams
- Hands-on experience implementing AI tooling to accelerate design-to-code workflows and automate design system consistency checks
- Takes initiative and demonstrates leadership in ambiguous, cross-functional environments - you can identify what needs to happen next and rally people around a direction without formal authority
- Systems thinker who builds foundations, not just features
- Opinionated about design quality with a point of view on what good design looks like
- Detail-oriented with exceptional craft sensibility for visual and interaction quality
- Low ego, strong collaborator who bridges design and engineering
- Comfortable receiving feedback on your work and adjusting direction when the team or constraints call for it — you care more about the system getting better than being right
- Pragmatic approach to balancing perfection with progress
- Clear communicator who can articulate tradeoffs and standards,
- Focused on enabling others and reducing friction for feature teams
- You document decisions and share what you learn so others can build on your work
- If you think you meet more than 50% of our requirements but fewer than 100% of them, please apply
What the job involves
- We're looking for a Senior Design Engineer II to help build and maintain our design system, improve UI quality and consistency across the app, and be the bridge between design and front-end engineering
- 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
- 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, 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
- 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 components faster
- First Year: Create a stable, predictable design-to-code workflow that feature squads rely on. Drive high adoption of system components in new feature work with visible consistency improvements across surfaces that previously diverged
- Lead the evolution of our component library in Storybook to become the canonical reference for UI behaviour and states. Establish guardrails that prevent UI drift before it starts, so feature squads ship faster with higher-quality UI without needing to check in with you on every decision

Our take
Kit, formerly ConvertiKit was founded in 2013 to help online creators and bloggers make money through email marketing. The company has amassed more than 550,000 creators that reach 590+ million fans.
Following a boost to email marketing engagement rates, Kit’s strong existing network put it in a good position to take advantage of it. Add to that the increasing shift towards eCommerce, and the company’s offering is increasingly looking like a smart solution for content creators looking to monetize.
Kit’s acquisition of musician marketing platform FanBridge sees the platform scooping up musicians looking to explore alternative revenue streams online following the pandemic throttling of tours and live gigs. With plans to add Spotify and BandsInTown integrations, as well as ‘tip jars’, this is an interesting direction to see the email marketing company expand into.
