360 Soc Jobs (NOW HIRING)

Job Summary:
ECS is a global organization specializing in advanced technology solutions, and they are seeking a SOC Threat Hunter to proactively identify and mitigate advanced cyber threats. The role involves developing threat hypotheses, analyzing security event data, and conducting structured hunts to uncover suspicious behaviors and control gaps.
Responsibilities:
• Develop and execute hypothesis-driven hunts across enterprise, cloud, endpoint, identity, and network data sources
• Analyze anomalous behavior, suspicious activity, and attacker tactics, techniques, and procedures (TTPs)
• Use SIEM, EDR, network, log analytics, and threat intelligence tools to identify potential compromise or unauthorized activity
• Validate hunt findings, assess potential impact, and determine whether escalation to incident response or SOC operations is required
• Translate hunt findings into detection logic, analytic requirements, alert tuning recommendations, and monitoring use cases
• Identify gaps in logging, visibility, correlation logic, and alert coverage
• Partner with SOC analysts, Splunk engineers, security engineers, and threat intelligence analysts to improve detection fidelity and coverage
• Support development of repeatable hunt playbooks, queries, dashboards, and analytic procedures
• Research emerging threats, adversary behaviors, malware trends, vulnerabilities, and exploitation techniques relevant to the environment
• Map threat activity and hunt hypotheses to recognized frameworks such as MITRE ATT&CK
• Incorporate threat intelligence into hunt planning, detection enhancement, and investigative workflows
• Provide feedback to threat intelligence teams on observed activity, intelligence gaps, and collection priorities
• Support advanced investigations by correlating security events, system activity, user behavior, and contextual data
• Document investigative steps, evidence, conclusions, and recommended follow-up actions
• Coordinate with SOC Tier 2 and Tier 3 analysts, forensics personnel, and incident response teams during escalations
• Assist with post-incident hunt activity to identify related indicators, lateral movement, persistence, or additional affected assets
• Produce clear hunt reports, summaries, findings, and recommendations for technical and leadership audiences
• Track hunt outcomes, recurring patterns, detection gaps, and operational metrics
• Contribute to continuous improvement of SOC processes, analytic standards, and knowledge management resources
• Stay current with adversary tradecraft, detection engineering practices, and security analytics techniques
Qualifications:
Required:
• U.S. Citizenship with ability to obtain and maintain a DOE “L” clearance after start.
• 5+ years of experience in cybersecurity operations, threat hunting, incident response, detection engineering, security monitoring, or related roles
• Hands-on experience using SIEM, EDR, network security, endpoint telemetry, cloud logging, and/or log analytics platforms
• Strong understanding of adversary tactics, techniques, and procedures; common attack paths; and enterprise security controls
• Experience developing or using hunt hypotheses, detection logic, investigative queries, and analytic playbooks
• Ability to analyze large volumes of security data and distinguish suspicious activity from benign behavior
• Strong written communication skills, including the ability to document findings, evidence, and recommendations clearly
Preferred:
• Experience with Splunk, EDR platforms, packet analysis, cloud security telemetry, identity logs, or scripting for data analysis
• Familiarity with MITRE ATT&CK, Cyber Kill Chain, NIST, or other cybersecurity frameworks
• Experience supporting SOC operations, incident response, malware analysis, forensics, or threat intelligence functions
• Knowledge of Windows, Linux, networking, authentication, cloud services, and common attacker tooling
• Certifications such as GCIH, GCIA, GCFA, GNFA, GREM, CISSP, CySA+, Security+, or equivalent experience
