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.
• Detection, Playbooks, Threat Intelligence, and Continuous Improvement Response: Tune and improve detections, automate repetitive workflows, and drive incident response improvements. Refine existing rules and propose new use cases based on investigations and recurring patterns; enrich cases with threat intelligence (IOCs and TTPs) and incorporate those learnings into future detections and playbooks; Contribute and evolve response playbooks for major incident types (account compromise, endpoint malware, SaaS abuse, suspicious network activity), participate in post-incident reviews with root-cause analyses and practitioner-level technical narratives, and recommend prioritized, practical prevention and mitigation improvements. Conduct targeted threat hunts (e.g., OAuth abuse, living-off-the-land binaries, credential-stuffing against legacy protocols), define and track alert-quality KPIs (true/false positive ratios, suppression coverage), and collaborate to improve MTTD/MTTR.
