Senior Software Engineer, Care Experience

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy. The Care Experience team is transforming how Toast supports its customers across chat, voice, and agent-assisted channels. We build the intelligent platforms and tools that power every support interaction—helping agents resolve issues faster, improving AI-driven self-service, and ensuring customers get accurate, timely help when it matters most.

This is a high-impact domain. Support systems must operate reliably under urgent, business-critical conditions, integrate deeply with customer, device, and account data, and scale across millions of interactions while maintaining trust, accuracy, and speed. The platforms built by this team directly shape how effectively Toast can reduce friction, resolve issues end-to-end, and deliver a differentiated support experience as we grow—modernizing our core support infrastructure through a unified contact center platform foundation and AI-driven capabilities that improve routing, resolution, and outcomes.
