• Administer and optimize monitoring stacks; finetune alert thresholds, develop custom probes, and deliver concise "quicklook" reports to stakeholders.
• Harden operating systems (Windows, RHEL/CentOS, Ubuntu) and container images, applying CIS Benchmarks and conducting baseline compliance scans.
• Review source code snippets (Python, Ruby, Java) for OWASP and CIS guideline violations; recommend secure coding practices.
• Automate repetitive security tasks using lightweight scripts (Python, Bash) to increase efficiency and reduce human error.
• Collaborate with DevSecOps teams to embed security controls throughout CI/CD pipelines (Jenkins, GitLab, Azure DevOps), ensuring secure deployment of applications.
• Provide expert guidance to developers on secure coding, threat modeling, and testing methodologies.
• Mentor junior analysts on monitoring, logging, and documentation best practices.
• Author internal knowledgebase articles, develop training materials, and conduct short workshops to elevate team capability.

REQUIRED SKILLS & EXPERIENCE:

• Minimum of 4years of experience in IT security, including 2years in a federal or ISSOequivalent role such as System Security Officer or Security Analyst.
