An Agent Operator is the person who defines, deploys, evaluates, and optimizes the AI agents running a go-to-market organization. The role was named by Sophie Buonassisi at GTMnow in May 2026.
The four-stage loop: define the agent's job in writing, deploy it on the right stack, evaluate output against a measurable rubric, optimize prompts and context weekly. Without the loop, agents drift and output degrades silently.
The complementary term GTM Engineer (defined at /gtm-engineering) describes the same role from the systems side: wiring CRMs, automating workflows, building pipeline infrastructure.
xAI's job posting “Head of GTM, Systems and Agents” names both halves in one title. The role is one job, not two.
Companies hiring for it right now: xAI (Head of GTM, Systems & Agents), Notion (GTM AI and Innovation Manager), Zapier (Director of GTM Innovation).
