Specialist, Network Security Analyst

About the role

As a Specialist, Network Security Analyst within the Network Security Strategy & Analysis team within the ISO Infrastructure Security team, you will use network, security, asset, configuration, and vulnerability data to identify risk, quantify technical debt, evaluate control effectiveness, and support strategic network security decisions. You will partner with Network Engineering, Network Security Operations, Infrastructure, Cloud, Identity, Architecture, and other security teams to convert complex data into validated findings, prioritized recommendations, dashboards, and measurable risk-reduction actions. You will explain complex concepts and influence others to adopt data-supported points of view while working on complex problems that require an in-depth evaluation of security controls and business context. This role does not own day-to-day administration or operations of network security platforms; instead, this team will use analysis to drive environmental hardening and risk reduction. Success requires technical depth, strategic thinking, strong analytical judgment, and the ability to lead work through influence across multiple teams.
