Job Description
At Zendesk, we’re on a mission to build the most advanced AI agents in CX, and the AI Agent Testing team within the AI Agents organization plays a critical role in ensuring those agents are reliable, robust, and ready to deliver real customer value. Our focus is on synthetic testing, evaluation workflows, validation frameworks, and tooling that help us measure quality, uncover failure modes, and ship with confidence.
As a Senior Fullstack Engineer on this team, you’ll be a key technical contributor shaping the systems, tooling, and workflows that power AI agent evaluation at scale. While this is a fullstack role, it leans more on backend development as we’re looking for someone who is deeply comfortable with APIs, event-driven systems, testing infrastructure, data workflows, and platform thinking, while also being able to design and deliver polished user-facing tools when needed.
You’ll collaborate closely with product managers, designers, data engineers, applied AI/ML partners, and fellow engineers to build internal and customer-facing capabilities that improve the quality of our AI agents. In this role, you’ll not only ship features end-to-end, but also help shape technical direction, raise the bar on engineering quality, and influence how the team solves complex problems.
Your work will directly impact how Zendesk validates and improves its AI agents, helping ensure our products are trustworthy, measurable, and effective.
