SIEM Deployment & Configuration

• Deploy and configure SIEM platforms (e.g., Splunk, QRadar, ArcSight, LogRhythm) across on-premises, cloud, and hybrid environments.
• Integrate log sources, including firewalls, endpoints, servers, applications, and cloud services.
• Maintain normalization, parsing, and correlation rules to ensure accurate alerting.

Alerting & Use Case Development

• Develop and optimize detection use cases for potential threats, vulnerabilities, and anomalous behaviors.
• Tune SIEM rules to reduce false positives while maximizing detection coverage.
• Collaborate with SOC Analysts to validate alert efficacy and adjust detection logic.

Incident Support & Forensics

• Assist SOC Analysts and Incident Response teams in analyzing events and investigating security incidents.
• Provide technical support for log analysis, threat correlation, and forensic investigations.
• Maintain documentation of detection rules, playbooks, and incident response procedures.

Monitoring & Maintenance

• Monitor SIEM health, performance, and data ingestion pipelines.
• Conduct regular audits of log sources, retention policies, and system configurations.
• Implement upgrades, patches, and security hardening of the SIEM platform.

Reporting & Metrics

• Generate reports on security alerts, system performance, and compliance metrics.
• Provide insights to management and clients regarding SIEM effectiveness and coverage.
• Assist in regulatory reporting (SOC 2, ISO 27001, HIPAA) through log retention and monitoring evidence.

Continuous Improvement

• Stay current on emerging threats, attack patterns, and SIEM platform enhancements.
• Recommend and implement improvements to detection capabilities, alert workflows, and system integrations.
• Collaborate on automation initiatives to streamline monitoring and incident response.

Qualifications

Required

• 3–5+ years of experience with SIEM platforms in a SOC or Managed Security Services environment.
• Proficiency with log source integration, normalization, parsing, and correlation.
• Strong understanding of network protocols, security technologies, and threat detection methods.
• Experience working alongside SOC teams, incident response, or threat hunting functions.
• Strong analytical, problem-solving, and documentation skills.

Preferred

• Experience with cloud-native SIEM solutions (e.g., Azure Sentinel, AWS Security Hub, Google Chronicle).
• Knowledge of scripting or automation for log ingestion, parsing, or alert workflows (Python, PowerShell, Bash).
• Security certifications such as Splunk Certified Architect, QRadar SIEM, GSEC, or CISSP.
• Familiarity with regulatory compliance standards (SOC 2, ISO 27001, HIPAA).
