Staff Platform Engineer-Front End

Staff Web Frontend Engineer (Frontend Platform) Location: San Francisco, CA (Hybrid) About The Company We’re building a modern, consumer-grade digital platform used by millions of people to access critical services in their everyday lives. Our product sits at the intersection of technology, accessibility, and trust—where performance, reliability, and user experience are non-negotiable. Engineering plays a central role in how we deliver value. We invest heavily in developer productivity, platform quality, and scalable architecture so teams can move fast without sacrificing craftsmanship. The frontend platform is a key part of that strategy—powering consistent, performant experiences across the entire product. We’re hiring a Staff Frontend Engineer to help shape the foundation of our web platform—powering high-quality, user-facing product experiences at scale. This isn’t a pure platform role. We’re looking for a product-minded frontend engineer who has shipped real features to users and also thinks horizontally—someone who builds systems other engineers rely on. What You’ll Do You’ll work on the foundation that makes product teams faster, while staying connected to real user-facing experiences.
