We are seeking an accomplished Senior Cyber Operations Analyst to join a high-performing Blue Team operating at the forefront of modern security operations. This is a technical role suited to an experienced analyst with strong engineering instincts, hands-on coding capabilities, and a deep understanding of incident response, detection engineering, and adversary tradecraft.

• Conduct security monitoring, alert triage, and continuous improvement of detection rules (core hours 9:00-17:30 on rotation).
• Lead and support incident response investigations, ensuring high-quality documentation and escalation.
• Mentor and support junior analysts, providing guidance, coaching, and technical oversight.
• Serve as a technical SME on client engagements; present findings and recommendations to senior stakeholders.
• Participate in alert testing, readiness exercises, and incident response tabletop sessions.
• Stay current on emerging threat intelligence, attacker techniques, and relevant research.
