Sebastian Mendo | Senior Product Designer
Sebastian Mendo is a Senior Product Designer at JPMorgan Chase, where he leads design for Casey AI—Chase's first customer-facing AI agent, shipped on voice and RCS and now the reference pattern for agentic work across the business. He previously shaped Chase MyHome onboarding and mortgage flows. Before banking, he designed AI-powered enterprise support at Salesforce and early GenAI content tools at WRITER. He combines product strategy, conversational AI UX, regulated design, and hands-on AI-native development.
Senior Product Designer specialized in agentic AI, voice and conversational UX, and shipping customer-centric products inside highly regulated environments.
I'm a Senior Product Designer at JPMorgan Chase working on Consumer AI. I've designed and shipped voice agents, RCS bots, and conversational flows within the regulated environment of consumer banking, partnering with flagship frontier AI labs.
Previously, I worked with some incredible people at Salesforce, Writer AI, and Chorus AI, where we designed AI experiences since before the launch of ChatGPT.
Outside of work, I'm a Cursor ambassador - I help other designers and builders get fluent with AI-native tools. I also like to design my own iOS apps, and participate in tech meetups and run clubs.
