About the Role

We at Abnormal AI are looking for a hands-on Security Operations/ Cyber Defense Analyst who thrives in a fast-paced, engineering-driven environment. You’ll be responsible for monitoring, investigating, and responding to security alerts across cloud, endpoint, identity, and application layers. You’ll work closely with detection engineers, cloud security, and IT teams to protect our hybrid environment from threats in real time.

Key Responsibilities

Detection & Triage:
Monitor alerts from tools like SIEM, EDR, IAM, CSPM, CDR etc.
Perform initial triage, enrichment, and correlation across multiple data sources.
Identify false positives and fine-tune rules with detection engineering.
Incident Response:
Lead containment, eradication, and recovery for endpoint, cloud, and identity incidents.
Document and communicate incidents through SOAR/Jira/ServiceNow workflows.
Perform root cause analysis and propose permanent preventive controls.
Threat Hunting & Analysis:
Proactively hunt using hypotheses mapped to MITRE ATT&CK.
Investigate anomalies across CloudTrail, Okta, GitHub, and other telemetry sources.
Collaborate with threat intelligence to identify emerging TTPs.
Automation & Process Improvement:
Build or enhance playbooks in SOAR (Torq or equivalent).
Create custom enrichment scripts and automations (Python, Bash, etc.).
Suggest new detection logic and operational improvements.
Reporting & Metrics:
Track and report operational metrics (MTTD, MTTR, incident categories).
Maintain documentation and lessons learned.
