About The Position

I'm hiring a senior frontend developer to own the frontend of Sauna, AI product for knowledge workers. This role is for someone who wants real ownership of the product experience, not someone who only wants to pick up predefined UI tickets. You’ll work on the part of the product users see and feel every day: the interface, interaction logic, responsiveness, feedback states, and overall clarity of the experience. The product itself is complex. Your job is to make it usable without hiding the complexity in a misleading way. This is a strong fit for someone who can take rough direction, make sound product decisions, and ship clean, thoughtful frontend work without needing constant step-by-step guidance.

Requirements

4+ years of frontend engineering experience.
Strong React and TypeScript skills.
Experience shipping complex production web applications.
Good product sense and design judgment.
Ability to work independently and make decisions.

Based in San Francisco or willing to relocate before starting.
