Responsibilities

You'll own the frontend of Sauna — shipping interfaces that feel instant, intuitive, and polished even when the underlying work is complex

You'll need to make product and design calls yourself, prototype quickly, and execute without waiting for perfect specs

Sometimes you'll implement designs. Other times you'll create them

Required

4+ years of frontend engineering with a portfolio that'll make the founders stop scrolling. We want to see complex, polished interfaces you've shipped

Expert in TypeScript and React — you understand reconciliation, when to bail out of renders, and how the browser actually works

Product sense and design intuition — you can take a rough product direction, sketch an interaction, and ship something that feels right. You notice when a transition is 50ms too slow or when an affordance is unclear

You make design decisions — You'll need to own some UX decisions, create simple designs when needed, and unblock yourself

High autonomy, low ego — you don't wait for permission or perfect specs. You ship, gather feedback, and iterate

You care about craft — details like loading states, empty states, error messages, keyboard shortcuts. The 1000 small decisions that make software feel good
