Senior/Staff Frontend Engineer

Are you ready to shape the future of restaurant tech – and the future of frontend development?

At Toast, we’re transforming how restaurants operate and grow. Our platform combines intuitive technology with a deep focus on customer success. From streamlining operations to delivering standout guest experiences, we empower restaurants to thrive through smart design and data-driven innovation.

Who We Are

Our mission is simple: to empower restaurants to thrive. We achieve this by empowering our developers as well. The Toast Frontend Platform Team (PLEX) plays a key role in enabling product teams to build and ship high-quality web experiences at scale. We own the component library, tooling, build systems, frontend CLI and guide the microfrontend architecture that supports hundreds of SPAs across the company.

We build some product surfaces (such as navigation and the homepage), but our primary mission is to elevate the frontend development process at Toast.

What We're Looking For

We’re looking for a Senior/ Staff Frontend Engineer with a passion for UI craft, scalable systems, and design systems. This role will guide the technical direction of Buffet, Toast’s cross‑platform component library – a foundation for Toast’s user experience across products. You’ll be central to how we build accessible, performant, international‑ready interfaces at scale and help define how component libraries evolve in a world of AI‑assisted development.

This is a high‑impact, cross‑functional role for an individual who excels at the intersection of design, engineering, and product development. You’ll work closely with design system leaders, product engineers, and platform teams to build systems that unlock frontend velocity and consistency.

About this roll*

In this role, you’ll:

- Lead technical strategy and architecture for Buffet, Toast’s design component library and underlying systems

- Champion best‑in‑class accessibility, performance, and internationalisation across frontend surfaces

- Evolve Buffet to meet the needs of AI‑assisted development, enabling safe and scalable component generation and usage

- Partner closely with Design, Product, and across Engineering to align system capabilities with team needs and product strategy

- Build and document scalable patterns, tooling, and abstractions to support experimentation and high‑quality delivery

- Influence cross‑team efforts around theming, responsive design, content surfaces, and shared UI frameworks

- Be a mentor, multiplier, and technical sounding board across the frontend community at Toast

Do you have the right ingredients*?

- 6+ years of experience building and scaling web applications, with deep expertise in modern frontend technologies (React, TypeScript, CSS‑in‑JS, etc.)

- Demonstrated leadership in building or maintaining component libraries or design systems

- Passion for frontend development – accessibility, animation, responsive design, and cross‑browser behaviour

- Strong systems thinking – able to anticipate scaling challenges, encourage reusability, and design for change.

- Enthusiasm for the future of development – curiosity about AI‑assisted coding, tooling, and emerging patterns

- Familiarity with analytics tooling (Amplitude, GA, etc.) and A/B testing platforms

- Experience influencing product and design decisions through code and conversation

- A bias for collaboration, learning, and raising the bar for frontend craft

*We love a good pun – and good design.
