Cyber Security Engineer II

Job Summary We are looking for a Sr. SOC Engineer with 3-5 years of experience to serve as the senior resource for our threat detection ecosystem. You will be responsible for the end-to-end lifecycle of our security operations infrastructure, from engineering high-fidelity correlation rules in the SIEM to orchestrating automated response playbooks in SOAR. Your goal is to move the SOC beyond reactive alerting by building a proactive, intelligence-driven defense posture that can identify and neutralize sophisticated adversaries in real-time. Key Responsibilities & Business Impact 1. Detection Engineering & Framework Alignment • Correlation Logic: Design, build, and maintain advanced detection rules within the SIEM/XDR environment that correlate disparate data sources (Identity, Network, Cloud, and Endpoint). • MITRE Integration: Map all detection capabilities to the MITRE ATT&CK Framework to identify visibility gaps and ensure comprehensive coverage against modern TTPs (Tactics, Techniques, and Procedures). • Logic Tuning: Conduct continuous "noise reduction" by fine-tuning alerting logic and suppression lists to maximize the signal-to-noise ratio for frontline analysts. 2. Security Orchestration & Lifecycle Management • SOAR Architecting: Develop and maintain automated response playbooks (SOAR) to standardize incident handling, from automated enrichment and evidence collection to one-click containment. • Tooling Ecosystem: Manage the health and integration of the SOC tech stack, ensuring seamless data ingestion from cloud providers (AWS/Azure/GCP) and SaaS applications into central monitoring hubs. • Continuous Improvement: Regularly audit log sources for "telemetry health," ensuring that critical security logs are being ingested correctly and meet compliance retention requirements. 3. Advanced Hunting & Incident Leadership • Proactive Hunting: Lead hypothesis-based threat hunting engagements, utilizing EDR and SIEM data to find "silent" lateral movement or credential harvesting that automated tools might miss. • SME Escalation: Act as the Tier 2 escalation point for high-priority security incidents, performing deep-dive forensic analysis and providing technical leadership during the containment and recovery phases. • Root Cause Analysis: Lead post-incident reviews to identify systemic weaknesses and implement automated technical controls to prevent recurrence. Required Qualifications Technical Experience • Experience: 3-5 years of hands-on experience in a Security Operations Center (SOC) or Security Engineering role. • SIEM/XDR Mastery: Deep technical proficiency with platforms such as Splunk ES, Microsoft Sentinel, Google Chronicle, or Palo Alto Cortex XDR. • Cloud Security: Solid understanding of monitoring cloud-native environments (log types like CloudTrail, VPC Flow Logs, and GuardDuty). • Querying & Scripting: Expert-level proficiency in query languages (KQL, SPL, or Lucene) and scripting languages (primarily Python or PowerShell) for automation and data manipulation. Soft Skills & Education • Education: Bachelor’s degree in Cybersecurity, Computer Science, or a related technical field. • Analytical Mindset: Ability to synthesize complex, fragmented data points into a cohesive narrative of an attack. • Collaboration: Strong ability to document complex workflows and lead technical training sessions for junior SOC analysts. Certifications (Highly Desired) • SOC & Detection: GIAC Certified Detection Analyst (GCDA), GIAC Certified Intrusion Analyst (GCIA). GCIH (GIAC Certified Incident Handler) • Vendor Specific: Microsoft SC-200, Splunk Core Certified Advanced Power User, or AWS Certified Security - Specialty.
