About Toast

Toast builds technology that helps food and beverage businesses run smoother, serve customers better, and grow with confidence. Our platform brings together the tools teams need to power daily operations—while turning complexity into clear, actionable insights. Were purpose-built for the pace of hospitality, and were investing in new experiences that make great businesses easier to run at any scale.

Bready* to make a change?

Our New Ventures team operates like a startup inside Toast. Were a small group building a new line of business from scratch on the foundation of the Toast platform, unlocking a new market with new customers, and we have a lot of room to decide how things should work.

Were looking for a builder — someone genuinely fullstack, as comfortable in a backend service as in a React front end, who follows a problem wherever it leads instead of stopping where their specialty ends. Youll work across backend, web, and our Android point-of-sale and handheld apps. Prior Kotlin isnt required; comfort learning a new platform is.

About this roll* (Responsibilities)

• Build end-to-end across the stack — backend services, APIs and data models, web front ends, and our Android point-of-sale and handheld apps — going wherever the product needs you.
• Get up to speed on unfamiliar platforms and codebases quickly — including Android/Kotlin.
• Be customer-interested and product-minded—curious about what operators actually need, and willing to have a point of view on what we build.
• Collaborate closely with a small cross-functional team, biasing toward putting things in the hands of customers as fast as possible.
• Navigate diverse, unfamiliar codebases across the Toast platform and consistently deliver high-quality code on timeline.
• Demonstrate a high degree of ownership in all aspects of development — including the unglamorous parts: testing, instrumentation, on-call, and cleanup.
• Leverage cutting-edge AI tools to enhance your development workflow, improve velocity, and help pioneer new approaches to building — contributing to a culture of innovation and productivity across the team.

Do you have the right ingredients*? (Requirements)

• A track record of shipping meaningful product to real users, with clear technical and business impact.
• Genuine fullstack range: youve owned features from backend service and API through to the client, and you have a real opinion about both ends.
• Solid backend fundamentals (Java, Kotlin, or similar) — distributed systems, asynchronous communication, event-driven architecture, API design, and integration patterns.
• Comfort with modern web front-end development (React or similar) and an eye for a usable interface.
• A credible track record of learning a new language, framework, or platform on the job and shipping production code in it.
• Demonstrated ability to deliver clean, maintainable, resilient code that withstands the test of time.
• Experience in 0→1 builds, and high comfort with shifting priorities and incomplete requirements.
• Strong communication and collaboration skills — you can write up a technical design, get alignment on it, and work well with product and design partners.
• A clear pattern of using AI tools to accelerate your work, and the ability to speak specifically about how you use them to ship better work faster.

Special sauce* (Nice to haves)

• Android development experience, particularly production Kotlin (or Java alongside it).
• Youve worked on early-stage products, internal incubations, or rapid experimentation teams.
• Experience with point-of-sale, payments, hardware-adjacent, or offline-first systems.
• Youve been the person on a team who fills whatever gap is open — and you enjoyed it.
