Senior Director, Data Science - Security Analytics

Meta is seeking an experienced analytics leader to build and run Security Analytics for Central Security. You will lead Data Science and Data Engineering as one integrated function and serve as the primary data partner to Meta's Chief Information Security Officer and his leadership team. This is a high-impact, high-visibility leadership role where you'll turn Security's strategy, risk, and execution into a trusted data system for decisions. Security is operating through a period of rapid change. AI is expanding the attack surface, agentic systems are changing how security work gets done, and leadership needs a clearer view of where Meta is exposed, whether controls work, and where to invest next. You'll own the measurement system that answers those questions. The Challenge -Create one integrated Security Analytics function that makes Meta's security posture legible and actionable across a fast-paced, rapidly evolving threat landscape -Establish a persistent model of Security health that connects risk to controls, investment, and outcomes -Build the DS and DE organization, standards, and data foundations needed to sustain it Ideal Candidate -A builder and scaler who thrives in extreme ambiguity — you have created measurement systems and operating models in undefined spaces, then scaled the teams and foundations behind them -Leadership across DS + DE — you set one vision across insight, measurement, instrumentation, and data infrastructure, and you know where each discipline should lead -Security, risk, and systems thinking — you reason from threats through controls to residual risk, distinguish activity from outcomes, and make uncertainty visible without making the output unusable -AI-native leadership — you use AI to change how analytics and security work gets done, not just to make the existing process marginally faster Executive presence with the credibility to shape the questions, not just answer them
