Staff Artificial Intelligence Engineer, Conversations

Square Messages is a messaging platform for merchants to manage conversations with their customers across multiple channels (SMS, email, etc.). Situated within the Square ecosystem, Square Messages has integrations with various Square products that enrich messages with appointment bookings, receipts, invoices, coupons, marketing, and more.

Messages is also home to Square Assistant - an AI-powered virtual assistant to help merchants serve their customers 24/7. Square Assistant responds to customers asking for help with their appointments, including cancellations, confirmations, and conversational rescheduling of appointments. For more nuanced customer requests, Square Assistant saves merchants time by utilizing an in-house large language model to suggest responses, as well as actions that integrate with the rest of the Square Ecosystem. In the year ahead, we plan to expand Square Assistant’s capabilities in many ways, like personalizing responses for each merchant or deploying larger language models in production., * Play a key role in designing and developing novel conversational AI systems within Square.
