Senior SOC Analyst
Lennar is a leading homebuilder dedicated to building quality homes and providing exceptional customer service.
The Senior SOC Analyst plays a critical role in leading advanced incident response efforts, managing escalations, and working closely with our MDR partner to ensure rapid detection, containment, and remediation of security threats.
Responsibilities
Incident Response & Threat Management
- Lead investigations of complex, high severity security incidents from detection through containment, remediation, and recovery, coordinating across internal teams and the MDR partner.
- Act as the primary escalation point for Tier 3 alerts and incidents and perform root cause analysis with actionable remediation plans.
- Serve as the primary liaison to the MDR provider: validate and triage MDR alerts, ensure alignment on response protocols and escalation procedures, and provide tuning recommendations to improve detection fidelity.
- Develop and maintain incident response playbooks, runbooks, and workflows.
- Analyze threat actor tactics, techniques, and procedures (TTPs) and translate findings into improved defenses and detection content.
Threat Hunting
- Conduct proactive, hypothesis-driven threat hunts across endpoint, identity, network, and cloud telemetry, leveraging threat intelligence and the MITRE ATT&CK framework to surface threats that evade automated detection.
- Operationalize hunt findings into durable detection logic and response procedures.
Automation & Process Improvement
- Identify recurring, manual, or heavily manual SOC processes and design automation to reduce analyst effort and accelerate response.
- Build, test, and maintain automated playbooks and response workflows in a SOAR platform (e.g., Torq, Microsoft Sentinel Automation Rules, Logic Apps) for enrichment, triage, containment, and case management.
- Develop, tune, and operationalize detection and correlation rules through automated validation and deployment.
- Measure the impact of automation against SOC performance metrics (MTTD, MTTR, alert volume, false-positive rate) and iterate based on results.
- Partner with Detection Engineering and Security Engineering to integrate tooling, close telemetry gaps, and standardize repeatable response.
Security Monitoring & Analysis
- Monitor and analyze logs and alerts across SIEM, EDR, identity, and cloud platforms.
- Correlate data across multiple sources to identify patterns, anomalies, and emerging threats.
- Maintain situational awareness of the external threat landscape and internal security posture.
Mentorship & Reporting
- Mentor Tier 1 and Tier 2 analysts, lead knowledge-sharing, and uplevel team investigative tradecraft and tooling proficiency.
- Document incident timelines, findings, and lessons learned.
- Track, analyze, and drive improvement of core SOC performance metrics (MTTD, MTTR, detection coverage, false-positive rate), and use them to prioritize tuning and automation efforts.
- Generate executive-level and technical reports on SOC performance and incidents, supporting compliance and audit efforts through accurate record-keeping and evidence handling.
Requirements
- Minimum 5-7 years of experience in a cybersecurity operations role, with at least 3 years in a Tier 2/Tier 3 SOC or escalation capacity.
- CompTIA Security+ or equivalent certification.
- Proven experience leading incident response triage, investigation, and remediation, including working directly with MDR partners.
- In-depth knowledge of security tools and technologies, including SIEM/SOAR platforms (e.g., Microsoft Sentinel), endpoint detection and response solutions (e.g., Microsoft Defender XDR, Palo Alto Cortex XDR), and ticketing systems (e.g., ServiceNow).
- Demonstrated ability to author and tune detection content (e.g., KQL in Sentinel/Defender) and operationalize it into production.
- Experience analyzing cloud security telemetry (e.g., Azure/Entra sign-in logs, AWS CloudTrail).
- Hands-on experience building or maintaining automated playbooks and response workflows in a SOAR platform.
- Strong understanding of network security concepts, operating systems, and malware analysis techniques.
- Familiarity with the MITRE ATT&CK framework and threat intelligence platforms.
- Excellent analytical, problem-solving, and communication skills, with the ability to work under pressure and manage multiple priorities.
Preferred Qualifications
- Certifications such as CISSP, GCIA, GCIH, GCFA, CySA+, eJPT/PJPT, CEH, SC-200.
- Scripting and automation skills (Python, PowerShell) for tooling, enrichment, and analysis.
- Experience supporting an EDR platform migration (e.g., Cortex XDR to Microsoft Defender XDR).
- Experience with or strong interest in AI-assisted triage and agentic SOC tooling to augment analyst workflows.
- Broader cloud security experience across AWS, Azure, and OCI.
- Experience with Microsoft Sentinel, Proofpoint, and Palo Alto Cortex XDR.
Work Environment
- Mandatory 4 days onsite; 1 day remote.
- On-call rotation may be required for critical incident response.
- Collaborative team environment with opportunities for growth and specialization.
