The role emphasizes critical thinking, analytical reasoning, and hands-on scripting to enhance SOC efficiency and detection quality.
Core Responsibilities

SOC Operations & MSSP Oversight

• Triage and investigate alerts from SIEM, EDR, identity, and cloud platforms
• Act as the internal escalation point for MSSP-generated alerts
• Provide direction and feedback to MSSP to improve alert quality and response consistency

Incident Investigation & Response

• Conduct structured investigations across endpoint, identity, and network telemetry
• Correlate data across multiple sources to determine root cause and scope
• Document incidents with clear timelines, impact assessments, and recommendations

Security Analytics & Detection Engineering

• Analyze logs and datasets to identify detection gaps and improve signal quality
• Tune detection logic and reduce false positives
• Develop and maintain detection use cases aligned to threat frameworks (e.g., MITRE Telecommunication&CK)
• Design, test, and deploy new detection rules and analytics based on emerging threats and internal findings

Automation & Engineering (Required)

• Build scripts (Python, PowerShell, or similar) to automate triage, enrichment, and case workflows
• Integrate tools and APIs to streamline SOC processes
• Improve case management workflows and response playbooks through automation

Continuous Improvement

• Propose and implement improvements to monitoring coverage and response processes
