Sr. Security Operations Analyst

Responsibilities

• Detection engineering: Architect and optimize real-time detection engineering playbooks across SIEM, EDR, and cloud security platforms to minimize false positives, accelerate triage, and scale threat-hunting capability.
• Investigation: Investigate suspicious activity, correlate findings across data sources, and document clear, timely case notes for each alert or incident.
• Incident command: Lead the response lifecycle for high-severity incidents as primary investigator or incident commander, ensuring seamless coordination and technical handoff across cross-functional teams.
• Containment: Execute containment actions under established playbooks, including endpoint isolation, disabling compromised accounts, and blocking malicious indicators.
• Threat hunting: Research indicators of compromise and apply threat intelligence to identify anomalous behavior.
• Rule tuning: Tune detection rules and use cases to reduce false positives and close visibility gaps, in coordination with engineering.
• Email threats: Investigate and remediate email-based threats such as phishing and business email compromise, from both user submissions and automated detection.
• Continuous improvement: Contribute to post-incident reviews and metrics reporting — MTTD, MTTR, alert volume, and false-positive rate — to support ongoing SOC maturity.
• Currency: Stay current on emerging threats, attacker TTPs, and industry frameworks such as MITRE ATT&CK.
