John Groetzinger is a Principal Engineer on the Cisco Customer Experience Engineering team with deep roots in network security. He spent 12 years as a technical leader in Cisco security TAC, where he built automation that started at a startup, survived the acquisition into Cisco, was adopted into the security product line, and won industry awards over a decade later. That security engineering background shapes how he approaches agent development today — designing agent architectures and evaluation frameworks, building internal agent platforms, and helping engineering teams across Cisco adopt agentic development. He is an AWS Certified Solutions Architect and has been practicing AI-native development since 2023.
