Senior Software Engineer, Product

At Decagon, the Senior Software Engineer will join the Product Engineering team responsible for building the conversational AI platform used by major enterprises to create and manage AI agents across multiple channels like voice, chat, and email. This team focuses on developing scalable frameworks and tools that empower customer experience teams to operate AI agents independently without engineering intervention. The role supports high-profile clients such as Hertz and American Airlines, contributing to a platform that handles complex workflows and diverse data.

The engineer will design and implement systems enabling customers to configure, train, test, and monitor AI agents with ease and confidence. Daily work involves collaborating closely with product and design teams to define requirements, review designs, and iterate on features. Responsibilities include building self-serve functionality, creating abstractions for diverse enterprise use cases, developing AI-powered tooling for non-technical users, and integrating new text and voice models into production. Ownership spans from architecture through deployment and ongoing iteration.

Candidates should have at least four years of software product development experience, proficiency in Python, and strong product thinking. They must be skilled at simplifying complex technical capabilities into user-friendly interfaces and adept at debugging large-scale systems. Experience with LLMs, prompt engineering, developer tools, observability, or security-sensitive systems is a plus. The position is full-time, based in San Francisco or New York City, and involves working onsite in a collaborative environment focused on excellence and velocity.
