YOUR ROLE AND IMPACT
Our IT Team is looking for a Security Operations Analyst II based in San Mateo responsible for leading in-depth investigations and incident response to escalated events and be involved in security-based projects as well as manage security solutions/systems_._ This role correlates data across SIEM/XDR, identity, endpoint, network, and SaaS/cloud sources; determines true blast radius; separates routine administrative activity from attacker behavior; and coordinates containment and remediation with Infrastructure/IT.
- Security Operations: Lead investigations for escalated incidents such as account compromises, endpoint malware, suspicious network activity, and SaaS misuse. Correlate data across SIEM/XDR, identity/SSO, endpoint/EDR, network, and cloud/SaaS logs to build attack timelines, identify entry vectors, and assess lateral movement. Coordinate containment and remediation with Infrastructure/IT—disabling or recovering compromised accounts, isolating infected endpoints and removing malware, validating EDR coverage and system integrity, and confirming cleanup success. Produce clear, audit-ready incident documentation detailing scope, evidence, actions, timelines, decisions, and resolution rationale. Act as an escalation point for the Service Desk and junior analysts, provide real-time guidance, and apply chain-of-custody and evidence-preservation practices for high-severity events, maintaining case files with hashes, screenshots, and IOC/IOA sets.
