Meta gives each on-call rotation its own AI teammate with a three-level autonomy ladder
AI Engineer · youtube · 2026-11-11
Meta engineers Swaapnika Motapothula, Chinmay Gandhi and Vlad Tsvang presented their on-call AI teammate design at the AI Engineer Code Summit.
Core design
- Instead of scattering tools, each rotation gets one AI teammate with shared context, its own identity, persistent memory, and explicit limits
- The system connects alerts, tickets, incident history, and code changes, so engineers no longer coordinate isolated automations
Autonomy ladder
- Investigation
- Drafting fixes for human approval
- Selective low-criticality execution, only when mistakes are cheap to detect and the agent has earned trust on that action
Critical production decisions stay human; code changes still go through normal review and CI.
Automation loops: triage, recovery from stuck runs, and shift handoffs are automated. Team-specific skills and memory carry expertise across engineers; corrections reopen work and become new evidence; memory entries can be promoted or retired.
The speakers stressed these demos show intended experience, not measured time savings — a rigorous study is reserved for later. Next steps focus on accepted mitigations, better feedback, and earning further autonomy.
