Defense in depth and cross-team communication are core pillars of Jane Street’s production engineering model.
Talk covers trading-environment-specific characteristics that make production engineering uniquely high-risk compared to standard ops roles.
Concrete case studies illustrate how Jane Street handles incidents across global stock markets.
