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 solid 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 ofSIEM 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)
SolidLinux investigation skills— process, network, and log-level analysis on Linux hosts is core to this role
Practical understanding ofcloud security fundamentals, ideallyAWS(IAM, CloudTrail, VPC Flow Logs, GuardDuty, etc.)
Exposure toKubernetes/container securityconcepts (pod logs, k8s audit logs, common container attack patterns)
Familiarity withCloudflarelogs (WAF, DNS, edge traffic) or similar CDN/edge security tooling
Working knowledge ofMicrosoft Defenderand basic Windows/macOS endpoint investigation
Strong analytical and investigative mindset — able to pivot from a single alert to a full incident narrative using raw log data
Understanding of the MITRE ATT&CK; framework and common attack patterns (cloud, container, endpoint), including mapping detections for coverage visibility
Experience acting as an escalation point for L1 analysts — validating their triage, coaching on quality, and owning shift handovers
Ability to author and maintain runbooks, SOPs, and knowledge base articles from incident learnings
Clear, structured incident documentation and communication skills
Experience and Qualifications:

3–5 yearsof hands-on SOC experience, with at least 1–2 years in anL2 analystcapacity handling escalations independently
Bachelor of Technology (BE/B.Tech), M.Tech/ME in Computer Science or equivalent.
Prior SOC experience in afintech, banking, or regulated industryenvironment
Exposure toAzure Sentinel/Azure logsin addition to AWS
Scripting ability (Python, Bash) for automation of repetitive investigation tasks
Certifications such asSecurity+, GCIH, GCIA, CySA+, or equivalent
Experience contributing to detection engineering (writing/tuning correlation rules, not just consuming them)
Familiarity with case management/ticketing tools (e.g., TheHive, Jira, ServiceNow)
Experience developing or tuningUEBA rules
Experience identifying and reporting log pipeline health issues (missing sources, parser errors, ingestion outages)
Experience supporting compliance/audit evidence requests (PCI-DSS, SOC 2, RBI/regulatory — relevant to fintech)
