The opportunity

Security Analyst, Core42 - Abu Dhabi, UAE. We are looking for a senior Security Analyst to anchor the technical depth of our 24x7 Security Operations Centre. This role detects, triages, investigates and responds to security incidents across our private-cloud platform and the enterprise services it supports. The successful candidate is a hands-on practitioner who can own an incident end to end - from the first alert in Splunk through containment, eradication and recovery - while also raising the quality of our detections and acting as a senior escalation point and mentor for less-experienced analysts. The environment is a private cloud built on OpenStack and Red Hat OpenShift, instrumented with Splunk (SIEM), Cribl (data pipeline), Elastic Security (EDR) and Corelight (NDR). Comfort working across virtualised and containerised infrastructure log sources is expected. The role reports to the SOC Manager and operates on a full-time, 24x7 rotational shift basis.

Your key responsibilities

Security monitoring, triage & detection

• Monitor security alerts and events in Splunk to identify threats, anomalies and malicious activity across the private-cloud platform and enterprise services
• Perform triage and investigation of security events, acting as the senior technical decision point on whether an alert represents a genuine incident
• Serve as the senior escalation point for front-line analysts, providing investigative guidance and validating findings before escalation
• Investigate EDR and NDR alerts involving malware, suspicious scripts, credential theft, lateral movement, persistence, ransomware and endpoint or network compromise

Incident response (full lifecycle)

• Own security incidents end to end across the full response lifecycle: identification, containment, eradication, recovery and post-incident review
• Execute containment and remediation actions in coordination with platform, infrastructure, network and application teams
• Lead the response on assigned incidents and coordinate cross-team activity to ensure timely investigation, escalation and resolution
• Develop and maintain incident response playbooks and standard operating procedures (SOPs), and drive their improvement after each major incident

SIEM, detection engineering & log pipeline

• Create, tune and optimise Splunk correlation searches, alerts, dashboards and reports to improve detection quality and coverage
• Write and maintain efficient SPL queries supporting investigation, hunting, reporting and detection engineering
• Reduce alert fatigue by tuning noisy detections, lowering false positives and strengthening correlation logic, weighing false-positive cost against miss cost when making tuning decisions
• Support onboarding of new log sources and validate log quality, parsing, field extraction and normalisation
• Manage and maintain Cribl Stream/Edge pipelines for log routing, filtering, enrichment and normalisation, optimising data flow and Splunk licence consumption

Threat hunting & intelligence

• Conduct hypothesis-driven threat hunts to uncover advanced persistent threats (APTs) and techniques that evade existing detections
• Map detection coverage to MITRE ATT&CK, identify and report gaps, and convert successful hunts into durable detections
• Apply threat intelligence and frameworks (MITRE ATT&CK, Cyber Kill Chain, Diamond Model) to enrich investigations and improve detection and response
• Identify patterns, trends and indicators of compromise (IOCs) to proactively detect and prevent recurrence

Documentation, reporting & governance

• Conduct root cause analysis (RCA) and produce clear incident reports for management and stakeholders
• Maintain accurate, detailed records of incidents, actions taken, evidence collected and lessons learned in the case-management platform
• Contribute to the continuous improvement of security monitoring use cases and detection rules
• Support audit and compliance requirements by providing evidence of incident-management activities

Working arrangement

• Operate within a 24x7 SOC, participating in rotational day, evening and night shifts, including weekends and public holidays on a rotational basis
• Meet defined acknowledgement, triage and escalation SLAs on each shift and complete structured shift handovers to maintain continuity of in-flight incidents

What we’re looking for

(a) Required skills / qualifications

• Bachelor's degree in Computer Science, Information Security, Cybersecurity or a related field; equivalent professional experience and certifications will be considered in lieu of a degree
• 5-8 years in security operations, incident response or SOC monitoring, with at least 2 years at a senior level
• Proven hands-on experience with Splunk Enterprise / Splunk Cloud - advanced SPL, dashboard development, correlation searches, alert creation and tuning, and administration
• Demonstrated experience with Cribl Stream / Cribl Edge - log routing, parsing, filtering, enrichment and pipeline management
• Strong background in incident analysis, investigation, evidence handling, escalation management and full-lifecycle response aligned with industry standards, including playbook and SOP development and RCA
• Elastic Security (EDR) and Corelight (NDR) for endpoint and network threat detection, investigation and response
• Threat frameworks: MITRE ATT&CK (including coverage mapping), Cyber Kill Chain and Diamond Model
• Strong understanding of networking: TCP/IP, DNS, HTTP/S, firewalls, proxies and IDS/IPS
• Proficiency in Windows and Linux environments
• Proficiency in Python, Bash or PowerShell for automation and analysis
• Familiarity with private-cloud and platform log sources: Red Hat OpenShift, OpenStack, Commvault, Scality and related infrastructure
• ServiceNow, Jira or equivalent ticketing/case management for incident tracking, evidence attachment, escalation notes and closure documentation

(b) Preferred skills / qualifications

• Splunk Core Certified Power User or Splunk Certified Admin
• Cribl Certified Admin
• GIAC certifications relevant to detection and response - GCIA, GCIH, GCDA or GCFA
• Blue Team Level 2 (BTL2) or equivalent hands-on defensive certification
• Experience monitoring OpenStack and Kubernetes/OpenShift environments
• Familiarity with detection-as-code practices (version control and peer review of detection content)
