Senior Software Engineer, Onboarding

Senior Software Engineer, Onboarding

As a Senior Software Engineer on the Onboarding team, you will design and build AI agents that complete onboarding work for restaurants. You will turn Toast systems' onboarding processes into reliable tools that agents can use to read state and take action.

Your primary focus will be defining 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. You will own the onboarding backend and reshape it for agent-driven flows that aren't known in advance.

Your success will be measured by more than just going live. It's about ensuring the restaurant was set up well, how ready they were for day one, and how much help they needed afterward.

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 processes, including payments, payroll, hardware, menus, and appointments, into reliable tools that 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 necessary.
• Partner with product, design, onboarding operations, and data science to turn onboarding problems into agents and product changes that can be tested and measured.
• Contribute to technical design and architecture, and help set engineering standards for AI-powered systems.

Requirements

• 5+ years of software engineering experience building and operating production backend systems in Kotlin, Java, or another object-oriented language.
• Experience building on Large Language Models (LLMs) where the model takes real actions through tools, in production or in serious side projects.
• Proven ability to own outcomes end-to-end: design, launch, rollout monitoring, measurement, and iteration.
• A product-minded builder who forms a point of view on what to build, not just how.

Nice to Haves

• Experience with customer onboarding, activation, growth, or workflow/task orchestration systems.
• Experience with experimentation or funnel analysis.
• Full-stack experience with React and TypeScript.
