Senior Full-Stack Engineer - Next.js & APIs | Toast

As a Senior Full-Stack Engineer on the Toast Local team, you will build solutions on the web to expand how guests discover, interact with, and order from local restaurants through Toast Local. Working closely with frontend, backend, and native mobile engineers (iOS and Android), you will lead web development initiatives across the full stack—from React and Next.js user interfaces to backend microservices and APIs. In this role, you will take complete ownership of features from architectural design and code deployment to rollout monitoring, guest experimentation, and performance analytics.
