Our take

Clerk's focus on developer-first authentication puts this UI engineering role at the intersection of security and user experience, two areas that rarely play well together. The challenge of making complex auth flows feel effortless could yield some genuinely innovative interface patterns.

Job description

# UI Engineer @ Clerk

About Clerk

Clerk is on a mission to solve user management once and for all. We are a globally distributed team dedicated to providing best-in-class developer experience, with obsessive attention to every detail. Today, we provide developers with full-stack React components and hooks like <SignUp/>, <SignIn/>, <UserProfile/>, useUser, and useOrganization. These APIs allow developers to build hard-to-get-right user and organization management flows. We believe that a component is worth a thousand APIs.

About the role

We're looking for a UI Engineer to help bring Clerk's developer experiences to life on the web. In this role, you'll work at the intersection of design and engineering to build immersive, high-quality web interactions using modern frontend tools, animation frameworks, and creative development techniques.

    • Who you are

  • 5+ years of hands-on experience building production-grade marketing websites with memorable, tasteful animations that drive engagement and conversions
  • Marketing-focused animation expertise with deep knowledge of scroll-triggered animations, hero sequences, WebGL effects, and creative development techniques that capture attention without overwhelming users
  • Strong React & TypeScript foundation with experience building complex marketing sites using modern frameworks (Next.js, Astro) and animation libraries (Framer Motion, React Spring)
  • Performance optimization mindset understanding how to create rich visual experiences that still load fast, work across devices, and maintain excellent Core Web Vitals scores
  • Visual storytelling sensibility with an eye for how motion can communicate brand values, explain complex products, and guide visitors through marketing funnels
  • Marketing collaboration experience comfortable working with brand designers, marketers, and growth teams to translate campaign concepts into compelling web experiences
  • Creative development background with a portfolio showcasing marketing websites that balance visual impact with conversion optimization

    • Nice to haves
