Staff Software Engineer, Product
About The Position
Decagon is hiring a Staff Software Engineer for Product Engineering, which builds the platform customers use to create, operate, and improve AI agents. The team develops reusable frameworks and agents for enterprise customer workflows across channels including chat, voice, email, and SMS. The role focuses on systems that help customers configure, train, test, and monitor sophisticated AI agents, with robust engineering foundations and abstractions that support varied use cases without customer-specific forks. The engineer works closely with product and design, participating in discovery, defining requirements, reviewing designs, and iterating through launch. The role stays close to customers to understand their use cases and owns features end to end, from technical architecture through deployment and post-launch iteration. The work includes self-serve configuration and deployment, AI-powered workflow tools, monitoring and analytics, and evaluating and integrating new text and voice models. The systems support critical workflows for Fortune 100 companies.
