About The Position

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. This is not a "click-through-the-console" SOC role — we’re looking for someone who can think critically, automate relentlessly, and own incidents end-to-end.

Requirements

• 5-7 years of hands-on SOC or Incident Response experience in a cloud-first or hybrid environment.
• Strong understanding of attacker lifecycle, MITRE ATT&CK, and threat actor TTPs.
• Experience with EDR (CrowdStrike preferred) , SIEM (Splunk preferred) , and SOAR (Torq, XSOAR, or Phantom) .
• Familiarity with AWS , Okta , and SaaS platforms .
• Proficiency in writing queries and automations using Python, SPL, or equivalent.
• Excellent analytical and investigative skills — capable of operating independently with minimal hand-holding.
• Strong documentation and communication skills for technical and executive audiences.

Nice To Haves

• Experience with CSPM/CDR/VM tools.
• Knowledge of Containers and Kubernetes security.
• Relevant certifications like CEH, Security+, GCIH, GCIA, or AWS Security Specialty .

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.
