Senior Fullstack Engineer (Frontend Platform)

Toast is driven by building the restaurant platform that helps restaurants adapt, take control, and get back to what they do best: building the businesses they love.
We connect employees, operations, and guests on a reliable, easy-to-use platform so restaurateurs can stay one step ahead of a rapidly evolving hospitality market.

Our mission is simple: empower restaurants to thrive, and we do that by empowering our developers too. The Toast Web Platform team plays a key role in enabling product teams to build and ship high-quality web experiences at scale. We own the tooling, build systems, frontend CLI, microfrontend architecture, and web developer experience that support hundreds of SPAs across the company.

This team is deeply technical and platform-oriented. While we own some product surfaces (like navigation and homepage), our primary mission is to elevate how the frontend is built at Toast.
We’re looking for a Senior Software Engineer who is passionate about modern frontend development, has strong systems thinking, and wants to make a huge impact on how hundreds of developers build for the web.

About this roll* (Responsibilities) 

Your work will directly accelerate our release cycles, reduce onboarding friction for new engineers, and enhance the reliability of critical restaurant-facing user interfaces.

• Lead the evolution of our shared frontend build system (Webpack, Vite, etc.)
• Drive improvements in our microfrontend architecture and tooling
• Enhancing our Node.js-based frontend CLI, scaffolding tools, and shared testing config
• Building internal tools to improve developer observability, debugging, and performance
• Partnering with other frontend teams to gather feedback, identify friction, and address gaps in our platform
• Monitoring the health and performance of deployed web apps using tools like DataDog, Splunk, and custom telemetry
• Shape org-wide best practices for frontend architecture, testing, and release workflows

Do you have the right ingredients*? (Requirements)

• 5+ years of professional experience in software development, ideally in frontend or web platform roles
• Strong experience with React, TypeScript, and frontend build systems
• Experience with Node.js, particularly in building dev tools and CLIs
• Exposure to backend systems (Java/Kotlin preferred) and understanding of API interactions
• A platform mindset — you're motivated by removing friction and enabling others
• Comfortable navigating ambiguity and working across many teams to drive alignment

Bonus: experience with microfrontend patterns, shared testing infrastructure, or GraphQL federation
