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.

Responsibilities

• 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.
• 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.

Requirements

• Bachelor’s Degree in the field of Computer Science, technology, or a related area with a master’s degree preferred.
• 2–5 years in Security Operations or Infrastructure/IT Operations with a security focus.
• 2+ years Windows/sysadmin experience; macOS/Linux a plus.
• 2+ years core networking (IP, DNS, ports, VPN, firewalls).
• Hands-on experience with SIEM/XDR, EDR, identity/SSO, and cloud/SaaS logs.
• Able to read Windows event logs, perform basic endpoint triage, and apply MITRE ATT&CK for triage.
• Strong written/verbal communication and incident leadership skills.
• CompTIA Security+ required and other security certifications preferred.
