Getting them to running service on Toast is the job of the Onboarding & Activation team, and increasingly of the agents we build to do that work for them.\nWe've shipped our first agent, and it's the start of many. Onboarding is a broad set of deep problems (menus, payments, hardware, payroll, staff), each a candidate for an agent that acts across Toast's systems instead of answering questions about them. It's a company priority: lower cost to onboard, less support volume, higher NPS, and far better visibility into how each restaurant is set up. You'll define how these agents get built: what they're allowed to do, how they recover when something goes wrong, and when they hand off to a person.\nSuccess means more than going live. It's how well the restaurant was set up, how ready they were for day one, and how much help they needed afterward. Those signals are real but delayed and noisy, and building evaluations that tell us an agent did the right thing, not just a plausible thing, before the restaurant opens is one of the harder problems here.\nAbout this roll* (Responsibilities)\nDesign and build AI agents that complete onboarding work for restaurants, from tool design and permissions through evaluation, guardrails, and production monitoring.\nTurn the Toast systems onboarding touches, including payments, payroll, hardware, menus, and appointments, into reliable tools agents can use to read state and take action.\nOwn the onboarding backend and reshape it for agent-driven flows that aren't known in advance.\nBuild evaluation and measurement so every launch is tied to real outcomes: setup quality, readiness to go live, and how much help restaurants need after launch.\nShip full-stack changes in the restaurant-facing setup experience when the work calls for it.\nPartner with product, design, onboarding operations, and data science to turn onboarding problems into agents and product changes we can test and measure.\nContribute to technical design and architecture, and help set engineering standards for AI-powered systems across the teams that contribute to onboarding.\nMentor other engineers through code review, pairing, and by sharing how you build with AI.\nDo you have the right ingredients*? (Requirements)\n5+ years of software engineering experience building and operating production backend systems in Kotlin, Java, or another object-oriented language.\nExperience building on LLMs where the model takes real actions through tools, in production or in serious side projects, with a practical grasp of nondeterminism, evaluation, and cost.\nProven ability to own outcomes end to end: design, launch, rollout monitoring, measurement, and iteration.\nA product-minded builder who forms a point of view on what to build, not just how, and works across PM, design, and operations rather than executing tickets.\nYou use AI coding tools like Claude Code as a core part of how you work, and you've helped others get better with them.\nSpecial sauce* (Nice to haves)\nExperience with customer onboarding, activation, growth, or workflow/task orchestration systems.\nExperience with experimentation or funnel analysis, and a working sense of when to believe a metric.\nEnough full-stack experience (React and TypeScript preferred) to ship front-end changes when needed.\nExperience with event-driven architectures.\nAI at Toast\nAt Toast, one of our company values is that we're hungry to build and learn.
