Staff Software Engineer, New Ventures

Location(s): US (remote), Boston (hybrid), or New York (hybrid) 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. We’re purpose-built for the pace of hospitality, and we’re investing in new experiences that make great businesses easier to run at any scale. About this role* We’re looking for a startup-minded engineer to join our New Ventures team as one of its earliest members. You will be a core builder on a 0→1 venture that we are validating and building from the ground up. As part of a small, focused engineering squad within this venture, you’ll help architect and build the experiences that will define this new business line. This role is intentionally open to a wide range of experience levels, although listed as Staff to start. We aren't looking for a specific number of years; we are looking for a scrappy, product-minded engineer who can use AI-assisted development to move at terminal velocity. You’ll be joining a tight-knit team of product, design, and engineering peers to turn a fuzzy early concept into a functional, shippable MVP and beyond. In this role, you will: Build from 0→1: Partner with a small team of engineers to architect and build the technical foundation for this new venture—writing the first lines of code and evolving them as we learn. Ship at Terminal Velocity: Use AI coding assistants, LLMs, and modern automation to 10x your output. You’ll focus on high-level logic and solving core user problems while leveraging tools to handle boilerplate and rapid iteration. Architect for Flexibility: Help design systems that are "just enough" to ship today but flexible enough to pivot tomorrow. You understand that in the early stages, the ability to change direction is a feature, not a bug. Create "Real" Experiences: Move beyond static mocks. You’ll build functional prototypes and clickable flows that feel like the final product, allowing the team to test hypotheses with real users immediately. Execute End-to-End: Operate as a true generalist. Whether it’s building out a new API, refining a UI interaction, or adjusting a database schema, you do whatever is necessary to keep momentum high. Make Smart Tradeoffs: Work with the team to decide when to "hack" a solution for a quick experiment and when to spend the extra time on a hardened foundation. Operate with Bias for Action: Run with a "ship-to-learn" mindset. You’ll validate assumptions via low-fi experiments, dogfooding, and rapid refinement rather than waiting for perfect specs. Collaborate across Disciplines: Partner closely with Design and Product to ensure technical feasibility is baked into the vision from the start, helping to shape the "what" and "why" through a technical lens. Do you have the right ingredients*? 0→1 Mentality: High comfort working in high-ambiguity environments where learning is the primary output and "done" is an iteration, not a finish line. Generalist Depth: You’re a builder at heart, comfortable jumping into any part of the stack—frontend, backend, or infra—to get a feature live, and willing to take on occasional Android work when needed. AI-Native Workflow: You have a clear, proven pattern of using AI tools (Cursor, Copilot, LLM agents) to accelerate your coding, debugging, and synthesis. You can speak specifically to how these tools help you ship better work faster. Product Intuition: You don't just "build to spec." You understand user needs and can translate complex workflows into interfaces and systems that feel intuitive and calm. Technical Scrappiness: You have a "builder" mindset. You’ve likely built side projects, worked at an early-stage startup, or participated in rapid experimentation teams where resourcefulness was key. Team-First Attitude: You thrive in small, collaborative pods. You’re proactive about align
