Senior Software Engineer, Frontend
About The Position
We're hiring a Senior Frontend Engineer to be the technical anchor for our Marketplace web rewrite — rebuilding the highest-traffic journeys and setting the frontend patterns the team will follow for the next 5 years. The roadmap is aggressive: international expansion (Mexico & Caribbean this year, Europe next), in-housing search from Algolia, consumer experience rebuild, new Hotel SaaS tool, and Spa as a major new vertical. This is a senior role with Staff-leaning scope and a clear growth path. There is an opportunity to become Tech Lead of the biggest features (full SRP and DLP rewrites) and expand cross-team influence across Marketplace Core, Growth, and Hotels. Since 2/3 of traffic goes to web, performance is business-critical (Core Web Vitals, SEO, caching, API design). The web frontend is also the launchpad for AI integrations (concierge chatbot, AI spa booker). The tech stack includes Next.js 16.x, App Router, React 19, Tailwind, and shadcn UI. We are also open to evaluating strong Full Stack engineers willing to learn React/Next.js.
