systems.
The squad also owns critical reliability and trust layers around AI systems: reasoning systems,
AI tools, evaluation frameworks and quality monitoring.
One of the team’s recent focuses has been making agents trustworthy enough to ship at scale
through evaluation pipelines and automated quality controls integrated into engineering
workflows.
