Overview
Toast is building a restaurant platform that helps restaurants adapt and grow. We are transforming how restaurants operate and how frontend development is done across the Toast Platform Team (PLEX). We own the component library, tooling, build systems, frontend CLI and guide the microfrontend architecture that supports hundreds of SPAs across the company.
This is a high-impact, cross-functional role for an individual who excels at the intersection of design, engineering, and product development. You will work closely with design system leaders, product engineers, and platform teams to build systems that unlock frontend velocity and consistency.
