  • Author and present detailed technical reports, incident summaries, and security posture assessments to both technical peers and executive leadership.
  • Evaluate, recommend, and assist in the implementation and optimization of new security technologies, including SOAR, EDR, and threat intelligence platforms.
  • Maintain a deep and current understanding of the global cyber threat landscape, including emerging TTPs (Tactics, Techniques, and Procedures), threat actors, and vulnerabilities.
  • Lead formal post-mortem and root cause analysis sessions following significant incidents to identify and implement long-term preventative measures.
  • Collaborate closely with infrastructure, network, and application teams to orchestrate the remediation of identified vulnerabilities and security misconfigurations.
  • Automate routine security operations tasks and workflows through scripting (e.g., Python, PowerShell) to improve team efficiency and response times.
  • Oversee the vulnerability management program, including the prioritization of discovered vulnerabilities and the tracking of remediation efforts.
  • Perform advanced malware analysis (static and dynamic) on suspicious files to understand their functionality, indicators of compromise, and potential impact.
  • Contribute directly to the development and refinement of the organization's overarching cybersecurity strategy, policies, and standards.
  • Ensure all security operations activities are documented thoroughly and adhere to established incident response plans and regulatory requirements.
  • Develop and deliver specialized training sessions and workshops for junior analysts to enhance their technical skills and analytical capabilities.
