Senior Software Engineer, Onboarding
Toast · Boston, MA
About this role
## Senior Software Engineer, Onboarding **Location:** Remote (US) ### About Toast Toast builds the restaurant platform that helps restaurants adapt, take control, and get back to what they do best—building the businesses they love. ### About this role (Responsibilities) - Design and build AI agents that complete onboarding work for restaurants—from tool design and permissions through evaluation, guardrails, and production monitoring. - Turn Toast systems onboarding touchpoints (payments, payroll, hardware, menus, appointments) into reliable tools agents can use to read state and take action. - Own the onboarding backend and reshape it for agent-driven flows that aren’t known in advance. - Build 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. - Ship full-stack changes in the restaurant-facing setup experience when needed. - Partner with product, design, onboarding operations, and data science to turn onboarding problems into agents and product changes we can test and measure. - Contribute to technical design and architecture, and help set engineering standards for AI-powered systems across teams. - Mentor other engineers through code review, pairing, and sharing how you build with AI. ### Do you have the right ingredients? (Requirements) - 5+ years of software engineering experience building and operating production backend systems in Kotlin, Java, or another object-oriented language. - Experience building on LLMs where the model takes real actions through tools (production or serious side projects), with a practical grasp of nondeterminism, evaluation, and cost. - Proven ability to own outcomes end to end: design, launch, rollout monitoring, measurement, and iteration. - Product-minded builder who forms a point of view on what to build (not just how), and works across PM, design, and operations. - Uses AI coding tools (e.g., Claude Code) as a core part of how they work, and helps others get better with them. ### Special sauce (Nice to haves) - Experience with customer onboarding, activation, growth, or workflow/task orchestration systems. - Experience with experimentation or funnel analysis, and a working sense of when to believe a metric. - Enough full-stack experience (React and TypeScript preferred) to ship front-end changes when needed. - Experience with event-driven architectures. ### Apply today Toast is committed to an accessible and inclusive hiring process.
