About the squad: Phantom Intelligence: This squad is responsible for building the AI orchestration layer powering our future products and agents. The team works on: autonomous agents, conversational workflows, LLM-driven automation systems, internal AI tooling, and the progressive replacement of legacy 'phantoms' with intelligent agent-based 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.
