You will be working across security and engineering teams to drive strategy, influence stakeholders, and develop detection and response automation leveraging both industry-standard and custom detection and response platforms. You’ll also work alongside Security Engineers and Analysts to identify critical assets and TTPs, assess the top risks, and evaluate potential attacks against Meta systems.Responsibilities\nProactively identify and prioritize areas of risk across the company Lead major cross-company workstreams to deploy capabilities from multiple security teams to mitigate this risk Apply domain expertise and an attacker's mindset to lead cross-functional initiatives aimed at strengthening incident detection and response capabilities for complex threats Perform TTP-based threat modeling for a wide variety of assets, including endpoints, mobile, servers, internal services, public and private cloud environments, and networking equipment Review the security architecture of large-scale custom and commercial systems, and independently propose logging, detection, and prevention controls Work with policy and legal teams to strengthen our standards and our governance Build response workflows and actions that auto-resolve false positives and provide context, scaling our ability to investigate Influence asset-owning teams and their leadership across Meta to adopt appropriate access control designs and operational processes Support security incident response in a cross-functional environment and drive incident resolution Build logging pipelines using our custom datasets and infrastructure\nQualifications\nUnderstanding of how to manage security risks in a fast-moving environment 10+ years of experience in offensive or defensive cyber operations, detection and response
