About the role

What you'll do

  • Build polished experiences at scale. Work with design to ship great UI/UX, but also own the less visible stuff that matters like page speed, cross-browser support, mobile responsiveness.
  • Master the product. Develop deep expertise and opinions in what we're building. Work with product and design to shape what we build, not just execute on specs.
  • Instrument and optimize. Implement observability for user interactions, core web vitals, and perceived performance.
  • Craft frontend and product infrastructure. Contribute to build systems, dev tooling, and deployment pipelines. Advocate for a better developer experience. Build internal tools that help the team move faster.

Who you are

  • 6+ years of experience working in a frontend engineering role
  • You have an eye for design. You have track record of creating beautiful experiences for the web. You care deeply about user experience and have an understanding of what might make one UI better than another.
  • You think in systems. You build infrastructure that makes future features easier. You know when to generalize and when to keep things specific.
  • You're a self-starter. You enjoy building 0 to 1. You're always looking for things that could use some TLC and finding ways to make them better without asking permission.
  • You care about the details. You care about micro-interactions. You think about what happens when the network is slow, when data is missing, or when users do unexpected things.
  • You’re a good teacher. You know how to explain ideas and trade-offs cross-functionally.
  • You have opinions. You have thoughts on different state management approaches, how to structure provider hierarchies, and whether that hook should be extracted or kept inline. You can articulate why you'd choose one abstraction pattern over another.
  • You're always learning. You've tried various coding and AI tools just out of curiosity. You want to know what the latest and greatest are and what problems they solve.
