About this role

The Security Operation Engineer will move beyond passive monitoring to actively manage, maintain, and remediate security events within a dynamic project environment. Unlike a traditional Level 1.5 SOC monitoring role focused solely on escalation, this position requires hands-on engineering, active remediation, vulnerability handling, and security tool management in a cloud environment. Key Responsibilities & Workflow Active Tool & Cloud Management: Manage and configure security infrastructure tools, endpoint protection, and Privileged Access Management (PAM) tools within a cloud environment. Incident Remediation: Take ownership of security alerts and perform active, hands-on remediation tasks (rather than just routing notifications to external desktop or system engineers). Vulnerability & Audit Management: Execute daily vulnerability assessments, run security scans, handle vulnerabilities, and collaborate/coordinate with third parties to conduct security scans and audits. Log Analysis & Infrastructure Monitoring: Utilize SIEM and log analysis platforms (such as RSA NetWitness, Splunk, or Elastic Search) to filter, analyze, and investigate security event data across network devices, firewalls, routers, and operating systems. x` Technical Qualifications & Competencies Security Tooling: Proven experience with SIEM platforms (RSA NetWitness, Splunk architecture/forwarders, Elastic Search), PAM tools (e.g., CyberArk), and Endpoint/Malware protection suites (e.g., Trend Micro). Operating Systems & Scripting: * Linux: Solid understanding of Linux environments, including basic bash scripting for file filtering and security frameworks (e.g., Metasploit). Windows: Advanced Windows administration capabilities, including system configuration, security commands, and directory security. Investigation Depth: Ability to perform deep, independent investigations of complex scenarios (e.g., intranet/air-gapped environment brute-force attempts) rather than relying strictly on Level 2 escalation.
