analytics, dashboards, reports, watchlists, and monitoring use cases.\nMap detection content to MITRE ATT&CK and validate coverage against relevant attack techniques and business risks.\nPerform technical tuning to reduce false positives, duplicate alerts, and unnecessary noise while preserving or improving detection coverage.\nWork with the SOC Analyst Supervisor and analyst team to translate operational feedback, incident findings, and investigation pain points into engineering improvements.\nDevelop and maintain SOAR playbooks, API integrations, scripts, and automated workflows for enrichment, triage, containment, notification, and case management.\nMonitor platform health, connector status, ingestion, licensing, performance, capacity, availability, and security-control effectiveness.\nProvide L2/L3 technical support for complex investigations, security-platform issues, high-severity incidents, and advanced escalations.\nSupport threat hunting, malware and telemetry analysis, incident response, root-cause analysis, and post-incident technical improvements.\nMaintain technical documentation, architecture diagrams, configuration baselines, build procedures, support runbooks, and change records.\nCoordinate with infrastructure, network, cloud, identity, and application teams to resolve telemetry gaps and implement required security controls.\nContribute to technology evaluations, proof-of-concept activities, platform migrations, upgrades, and the continuous maturity of SOC capabilities.\nRequirements\nYour experience, skillset, and qualifications will help you succeed in this position and grow with the team.\nBachelor’s degree in Cyber Security, Information Technology, Computer Science, Engineering, or a related field.\nA Master’s degree in Information Security or a related discipline will be considered a plus.\nAt least 5 years of proven professional experience in cybersecurity, including a minimum of 3 years of hands-on experience within a SOC environment, covering SOC engineering, security operations, incident response, or related security engineering activities.\nProven experience implementing, administering, integrating, or

technologies.\nExperience with SOAR platforms, security orchestration, automated enrichment, incident workflows, and API-based integrations.\nStrong experience with EDR/XDR technologies, preferably CrowdStrike Falcon, Palo Alto Cortex XDR, Microsoft Defender XDR, or similar platforms.\nExperience with Palo Alto Networks firewalls, Panorama, Cortex technologies, or comparable network-security platforms.\nFamiliarity with NDR, IDS/IPS, vulnerability-management, email-security, threat-intelligence, and case-management technologies.\nStrong knowledge of security monitoring, detection engineering, alert tuning, incident investigation, threat hunting, and technical escalation practices.\nExperience onboarding and troubleshooting log sources through syslog, APIs, agents, collectors, and cloud-native connectors.\nGood understanding of Windows, Linux, Active Directory, Microsoft 365, identity platforms, networking, DNS, proxies, VPNs, and common network protocols.\nFamiliarity with Microsoft Azure, AWS, or other cloud environments and their native security-monitoring capabilities.\nGood understanding of MITRE ATT&CK, attacker tactics and techniques, and common scenarios such as phishing, malware, credential theft, lateral movement, command-and-control, and data exfiltration.\nScripting and automation experience using Python, PowerShell, Bash, KQL, SPL, or similar languages and query technologies.\nRelevant industry certifications will be highly appreciated, such as Microsoft SC-200 or AZ-500, Palo Alto Networks, CrowdStrike, Splunk, IBM QRadar, GIAC, CompTIA CySA+ or Security+, or other vendor-specific certifications related to SIEM, XDR, cloud security, automation, and incident response.\nStrong troubleshooting, analytical, technical documentation, and
