About the Team

The Agent SWE team at Decagon deploys the most advanced conversational AI agents to our customers that impact millions of users and directly drive Decagon’s growth.

Our mission is to deliver magical support experiences — AI agents working alongside human agents to help users resolve their issues.

About the Role

In this role, you will

• Lead a team to design and build AI agents that outperform human agents in managing complex customer interactions and driving customer retention
• Collaborate closely with enterprise customers across a number of verticals, understand their needs and transform these pain points into magical AI agents
• Partner with product, design and research to identify cross-customer trends that guide the evolution of Decagon’s agent building platform and research efforts
• Contribute to team strategy and help define the future of AI customer support agents

Your background looks something like this

• Have 2+ years of engineering management experience
• Have 7+ years of industry experience in software engineering
• Proficiency with Python, Typescript and asynchronous programming
• A high degree of comfort digging into systems failures within deep technology stacks using any tool necessary
