Senior🎓
Top SchoolCaitie Mccaffrey is a seasoned software leader and architect with 12+ years building large-scale, secure distributed systems across Microsoft, Twitter, HBO, and game studios. She has led teams from incubation to GA—most notably growing Azure Sphere Security Services from a 2-person research project into a 20-engineer product protecting IoT devices at scale. At Twitter she drove observability improvements for services ingesting billions of writes per minute and halved critical alerts through reliability engineering and cross-DC replication work. More recently she’s been shaping CoreAI at Microsoft, co-leading the Model Context Protocol and advising executive leadership on AI strategy and tech transfer. Her background spans both entertainment-grade real-time systems (credits on Halo and Gears titles) and high-assurance security services, a blend that gives her a rare perspective on performance, reliability, and product security. Based in Seattle with a CS degree from Cornell, she also participates in standards and governance via Agentic AI and MCP stewardship.
