Staff Software Engineer, Applied AINew

The opportunity

Toast is looking for a Staff Software Engineer to join our New Ventures team and help build a new AI-powered product. You’ll tackle problems without an established playbook, make decisions that shape the product, and take ideas from early experiments to capabilities customers can depend on.

What you'll do

  • Own the design and delivery of core capabilities for a new AI-powered: product, from exploring an approach to launching it and improving it with customer feedback.

  • Turn ambiguous product problems into working software. Build prototypes to: test assumptions, identify what matters, and make deliberate decisions about what to evolve, rebuild, or stop.

  • Build LLM-powered workflows and agents, deciding where to use model: reasoning, tools, or conventional software to achieve reliable outcomes.

  • Define what good performance means for AI-powered capabilities. Build: evaluations around realistic customer tasks, investigate failures, and use the results to guide improvements.

  • Shape the backend services, APIs, and data models that let the product evolve: quickly. Anticipate scaling needs while keeping early solutions simple.

  • Partner with teams across Toast to deliver integrations, resolve technical: dependencies, and establish clear ownership of shared capabilities.

What they're looking for

  • Work closely with Product and Design to make tradeoffs across customer: experience, technical feasibility, reliability, latency, and cost.
  • Stay close to the code and production behavior: implement critical components, debug difficult problems, and own successful rollouts.
  • Raise the team’s effectiveness through technical feedback, mentoring, and: thoughtful use of AI coding assistants and agents across development, testing, and debugging.
  • –12 years of experience building backend services, APIs, and production software.
