Job description

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy.

Engineers at Toast build the mission-critical foundation that powers thousands of restaurants and local businesses every single day. From real-time order processing and resilient payment infrastructure to automated intelligent workflows, our technology solves high-stakes, real-world problems at scale. We value high technical standards, hands‑on execution, collaborative problem-solving, and building systems that directly impact our customers' success.

• International: Scaling Toast’s core platform globally. You'll tackle localization, multi‑currency architectures, international payment integrations, and regional compliance as we expand into new markets around the world.
• Retail: Building the next generation of omnichannel commerce tools for retail merchants. You'll architect solutions that unify inventory, point‑of‑sale systems, and real‑time transaction processing for businesses with physical and digital storefronts.
• Enterprise: Architecting high‑throughput, mission‑critical systems designed for multi‑location, enterprise‑scale brands. You'll focus on system reliability, massive data scale, custom menu and pricing engine configurations, and complex multi‑entity management.

We are hiring across multiple teams and levels. Your specific team, title, & level will be evaluated and determined during the interview process based on scope, technical depth, and experience.

A Day in the Life (Responsibilities)

• End‑to‑End Product Execution: Design, build, and ship complete features across the stack—from resilient backend services and APIs to intuitive, responsive web interfaces.
• Architect & Build: Create highly reliable, scalable systems using Java, Kotlin, and modern frontend frameworks (React, TypeScript) critical to Toast's core platform.
• 0-to-1 & Scaled Execution: Drive net‑new product development and tackle complex scaling challenges to keep our platforms fast, decoupled, and seamless for users.
• Technical Leadership & Quality: Turn ambiguous business goals into high‑quality, production‑ready code. Advocate for engineering best practices, robust testing, and deep system observability across the entire tech stack.
• Engineering Excellence: Elevate code quality across teams and mentor engineers to help raise the overall technical bar.

What You'll Need to Thrive (Requirements)

• 5+ years of software engineering experience building production‑grade web applications and distributed systems.
• Strong proficiency with Java, Kotlin, or other object‑oriented languages.
• Hands‑on experience with modern frontend frameworks (React, TypeScript) and a strong understanding of web architecture and UI state management.
• Experience with modern API design (REST, GraphQL) and relational databases or alternative data stores (e.g., PostgreSQL, DynamoDB).
• Proven ability to solve complex, ambiguous problems and collaborate across product, design, and engineering teams.
• Ability to work core EST hours if not located near a Toast office.

What will help you stand out (Nonessential Skills/Nice to Haves)

• A passion for removing "human-in-the-loop" friction through intelligent automation.
