As a Staff Frontend Software Engineer, you will be the technical anchor for our frontend organization. it is a role for a strategic thinker, an architectural pioneer, and a cultural catalyst. You will report directly to the engineering leadership and work closely with Product, Design, and Cross-Functional Engineering teams to set the standard for frontend excellence.

Elevate the engineers around you and partner with Product, Design, and backend to turn ambitious visions into technically sound, modular realities — keeping the design system and shared components a help, not a tax.
Experience: 8+ years in software/frontend engineering, with a track record at Staff/Principal level or leading large‐scale frontend initiatives end to end.
Deep, production‐proven React mastery — you understand how React itself works (reconciliation, rendering, the hooks model), not just the API, because most of our apps are plain React SPAs that own their
