Senior Machine Learning Engineer

Job Title: Senior Machine Learning Engineer Company: Zendesk Job Category: Machine Learning Roles & Responsibilities: Job Description The Mission: The enterprise software landscape is fracturing. We are transitioning from "Systems of Record" to "Systems of Action." Zendesk is leading this shift with the Resolution Platform, aiming to be the first CX company to secure $1B in AI\-driven revenue. To achieve this, we must solve the "Orchestration Trap." We are not just building features; we are building the high\-performance runtime that allows fleets of AI Agents to Perceive, Reason, and Act. Pushing the architecture further. The iterative planner works, but there are open questions we have not solved yet: how to handle plan decomposition when the goal is ambiguous, how to manage interference between memory tiers under concurrent sessions, how to make skill acquisition more selective (the agent acquires skills too eagerly today), and how to design multi\-agent delegation patterns where one agent hands off subtasks to specialized agents via A2A (the Agent\-to\-Agent protocol).
