Role Summary

As a SOC Analyst (Level 2), you are the escalation point for complex investigations and active incidents. You’ll take ownership of high-severity alerts, lead technical triage through containment, and coordinate with Incident Response, Cloud/Platform, Identity, and Engineering teams. You’ll also improve SOC quality by tuning detections, refining playbooks, mentoring Level 1 analysts, and driving post-incident learnings into better controls.

What You’ll Do (Core Responsibilities)

Advanced detection and investigation

• Take escalations from L1 and independently investigate complex, multi-signal alerts (identity compromise, cloud control-plane abuse, endpoint persistence, lateral movement, suspicious automation, data exfiltration).

• Perform deep log/telemetry analysis across SIEM, EDR, cloud logs, IAM signals, network telemetry, email security, and SaaS audit trails.

• Build and validate hypotheses, pivot across data sources, and produce clear incident timelines and scope assessments.

Incident response and containment

• Serve as technical incident lead for defined incident types/severities (or co-lead with IR), driving containment and eradication steps within authorized bounds.

• Execute and improve response playbooks for key scenarios (phishing/BEC, credential theft, token/key compromise, suspicious API activity, ransomware indicators, insider risk signals).

• Coordinate evidence collection and preservation to support legal/compliance needs and potential third-party investigations.

Threat intelligence and adversary tradecraft

• Enrich investigations with threat intel (IOCs, TTPs) and map observed behavior to frameworks (e.g., ATT&CK) to improve detection fidelity.

• Maintain watchlists and detection logic for priority threats relevant to cloud-first financial and digital-asset operations.

Detection engineering and SOC improvement

• Tune SIEM correlation rules, EDR policies, and alert thresholds to reduce false positives and increase signal quality.

• Propose and implement new detections for emerging techniques (identity + cloud abuse, OAuth/app consent attacks, API key leakage, CI/CD pipeline tampering).

• Improve runbooks and automate repetitive enrichment steps (SOAR workflows, scripts, queries).

Operational leadership

• Provide mentorship and real-time guidance to L1 analysts; improve escalation quality through coaching and feedback.

• Manage shift handovers for active investigations and ensure high-quality case documentation.

• Contribute to SOC metrics (MTTD, MTTR, false-positive rate, escalation accuracy) and continuous improvement efforts.

What We’re Looking For (Minimum Qualifications)

• 2–5+ years of SOC / incident response / security operations experience (or equivalent hands-on experience in a fast-paced production environment).

• Strong ability to investigate across cloud security operations, endpoint security, identity, and core network fundamentals.

• Proficiency with at least one SIEM and common SOC tooling (e.g., Splunk/Elastic/Sentinel; CrowdStrike/Defender; Jira/ServiceNow).

• Ability to write clear incident documentation: timelines, scope, impact, containment actions, and recommended remediations.

• Comfort operating in an on-call or shift environment (depending on coverage model).

Nice to Have (Preferred)

• Detection engineering experience: correlation rules, Sigma/KQL/SPL, alert pipelines, SOAR automation.

• DFIR fundamentals: triage acquisition, volatile vs. non-volatile evidence, endpoint artifact analysis.

• Container/Kubernetes logging and runtime security exposure.

• Practical scripting (Python/Bash) for analysis and automation.

• Digital-asset ecosystem exposure and 24/7 trading operations familiarity.

• Certifications (optional): GCIH, GCIA, GCED, SC-200, AWS Security Specialty, or equivalent.

What Success Looks Like (First 90 Days)

• Independently lead investigations for high-severity alerts with strong scoping, decisive containment, and clean cross-team coordination.

• Reduce recurrence of common incidents by driving tangible improvements (detections, playbooks, IAM hardening recommendations).

• Improve L1 escalation quality through coaching and better runbooks.

• Deliver measurable SOC enhancements (e.g., tuned rules reducing false positives, new detection coverage, automation that reduces triage time).

Working Style We Value

• Calm, structured response under pressure.

• High ownership and strong communication across technical and non-technical stakeholders.

• A continuous-improvement mindset: every incident becomes better detections, better controls, and better resilience.
