Toast is building the restaurant platform that helps restaurants adapt, take control, and get back to what they do best: running the businesses they love. We’ve grown into a leading hospitality software company in the U.S., and are now entering our next phase of growth—one defined by scale, complexity, and a new class of enterprise customers. Every restaurant is unique, and a restaurant’s menu expresses its individual brand and product offerings. Inside a Toast restaurant, the definition of the menu becomes the common language between guests, servers, and the kitchen. In our digital ordering products, a great menu serves as both a billboard and a roadmap to an excellent dining experience. It is the central hub for restaurant configuration– it determines what guests can order, how the dishes are presented and priced in different contexts, where they are routed for fulfillment and how they are coursed, how they are prepared, whether the ingredients are still available, and how they are classified for reporting. A menu is always evolving: kitchens create new dishes, managers experiment with pricing and presentation, and staff optimize the menu for restaurant operations. We create products to satisfy the vast breadth of our restaurants, from single-location coffee shops to complex enterprise brands with thousands of locations. We offer an extremely powerful and configurable menu platform, and our team exists to ensure that this flexibility can be managed effectively at any scale. This includes feature-rich menu data models, APIs for both first and third party integrations (eg: DoorDash and other ordering partners), and the user experiences for configuring menus that meet a vast variety of needs, from complex customer segments (eg: Pizza shops) to our evolving Retail platform. We are looking for a visionary engineer who is motivated by these challenges and eager to transform our menus architecture to meet the dynamic needs of our customers and our rapidly gro
