About the Role:
Zeta is building out its Security Operations Centre function, running onAWS OpenSearchas our core SIEM. We are looking for aSOC L2 Analystwith a strong investigative mindset and hands-on comfort operatingwithout a traditional GUI-driven workflow- this role requires fluency in query languages to search, correlate, and triage data directly.
You'll be one of the early analysts shaping detection and response practices across a modern, cloud-native, hybrid environment spanning Kubernetes microservices, multi-cloud infrastructure, and traditional corporate IT.
You will be investigating and monitoring across:
  • Cloud & Infrastructure:AWS (primary hosting for all workloads/resources), Azure (logs), Kubernetes microservices
  • Edge/CDN & Network Security:Cloudflare
  • Endpoint:Microsoft Defender (corporate IT), macOS endpoints
  • Primary OS for incidents:Linux (majority of incident volume), with Windows/macOS corporate IT coverage
  • SIEM:AWS OpenSearch (query-language driven - no dedicated analysis GUI)


Responsibilities:


1. Monitoring & Escalation Handling
  • Perform full-time monitoring alongside L1, actively working the alert queue during high-volume periods, while also handling escalations from L1 analysts.
  • Act as the primary escalation point for all L1-escalated alerts and incidents receive and validate escalated alerts/incidents, performing deeper investigation to confirm scope, impact, and root cause.
  • Perform detailed investigation, log correlation, and root-cause analysis across multiple data sources - AWS, Kubernetes, Cloudflare, Azure logs, Defender, and Linux/macOS endpoints.
  • Write and runOpenSearch Query DSL / Lucene queriesdirectly against raw log data to pivot, correlate, and build full incident timelines (this is the primary analysis method - there is no GUI-driven investigation path).
  • Determine incident severity, scope, and business impact validate true positive vs. false positive at a deeper level.
  • Escalate confirmed major/high-severity incidents to the L3/Incident Response team or CSIRT leadership per the incident response plan, including a full technical summary, supporting evidence, and recommended actions.
  • Coordinate with L3/Incident Response teams for complex or high-severity incidents.
    • 2. Threat Analysis & Detection Support
  • Conduct threat hunting based on IOCs, IOAs, and threat intelligence feeds.
  • Support ideation and testing of new detection use cases, correlation rules, and dashboards, in coordination with the detection engineering/L3 team.
  • Identify and report logging/health issues (e.g., missing logs, parser errors, data source outages) for timely resolution.
  • Tune and recommend improvements to detection rules, correlation logic, and SIEM use cases based on false positives/negatives observed during investigations develop tested tuning solutions and hand them to L3 analysts and build teams for deployment.
  • Create new detection use cases, tune existing correlation rules, build/modify dashboards, develop and refine UEBA rules, and map detections to theMITRE ATT&CK frameworkfor coverage visibility.
    • 3. Playbook, SOP & Knowledge Management
  • Develop and refine investigation steps for scenarios not covered by existing playbooks, and document these as new/updated runbooks for L1 use.
  • Update and improve SOPs, playbooks, and knowledge base articles based on incident learnings.
    • 4. L1 Oversight & Mentoring
  • Mentor and provide technical guidance to L1 analysts, including alert triage decisions and use of investigation tools.
  • Own L1 shift handovers, and train/mentor L1 analysts on alert handling and escalation.
  • Review quality of L1 alert closures and escalations provide feedback and coaching.
  • Support training and onboarding of L1 analysts on tools, triage procedures, and escalation criteria.
  • Ensure smooth shift handovers between L1 and L2, and across shifts.
    • 5. Compliance & Audit Support
  • Assist with compliance and audit requests requiring deeper technical evidence or investigation summaries.
    • 6. Continuous Learning & Feedback
  • Continuously expand knowledge of emerging threats, attack techniques, and best practices through ongoing training and self-study.
  • Stay current on emerging threats, TTPs, and vulnerabilities relevant to our environment, and translate this into actionable detection improvements.

    • Skills:


  • Strong working knowledge of SIEM query languages- direct experience withOpenSearch Query DSL, Lucene syntax, KQL, SPL, or equivalentis essential (you must be comfortable querying raw data without relying on prebuilt dashboards)
  • Solid Linux investigation skills- process, network, and log-level analysis on Linux hosts is core to this role
