On Call Ai Agent Jobs (NOW HIRING)

The Senior Manager, Engineering - AI Agents will lead the development and delivery of Five9's AI Agent software platform, which provides customers with fully autonomous self-service agents for customer support, sales, and services use cases in the contact center. This is one of the hottest areas of application for AI Agent technology! 

This role is responsible for building and managing a high-performing engineering team that develops scalable, reliable, and production-grade AI-powered systems used in real-time customer conversations. 

You will be responsible for hiring and developing engineers, improving engineering processes, and enabling strong execution across the software development lifecycle. While this is a management role rather than an individual contributor position, the ideal candidate will bring strong technical credibility with engineers and guide architecture discussions, technical decisions, and engineering best practices. 

You will collaborate closely with Product, SRE, Support, and other engineering teams to deliver an enterprise-grade platform while fostering a culture of operational excellence, ownership, and customer empathy. 
This role is hybrid. 3 days a week (M, W, TH) in our San Francisco office is required.
