Our IT Team is looking for a Security Operations Analyst II 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.
