Role Summary

As a SOC Analyst (Level 1), you are the first line of defense for monitoring, triaging, and escalating security alerts across Keyrock’s cloud‑first, high‑availability trading environment. You will follow playbooks/runbooks to validate alerts, enrich investigations with context, and ensure timely escalation to Level 2/Incident Response.

What You’ll Do (Core Responsibilities)

• 24/7 monitoring and alert triage across SIEM/EDR/cloud security tooling; identify false positives vs. credible threats and set appropriate severity.
• Initial investigation and enrichment: gather relevant logs/telemetry, add context, and document findings clearly in the case/ticketing system.
• Escalation and coordination: elevate confirmed/suspected incidents quickly and cleanly to L2/IR with a complete handoff (timeline, scope, IOCs, actions taken).
• Runbook execution: follow SOPs for common events (phishing, suspicious logins, endpoint detections, cloud key/token risk, malware alerts, data exfiltration signals), including containment actions you’re authorized to perform.
• Threat‑aware analysis: map alerts to adversary behaviours (e.g., MITRE ATT&CK techniques) to improve understanding and escalation quality.
• Operational hygiene: maintain accurate shift handovers, update watchlists and investigation notes, and identify recurring alert patterns for tuning recommendations.

What We’re Looking For (Minimum Qualifications)

• 0–2 years in a SOC / security monitoring / IT operations role (or equivalent hands‑on experience, internships, labs).
• Practical knowledge of security fundamentals: networking, DNS, HTTP(S), identity/authentication, and malware basics.
• Familiarity with log investigation and event triage concepts.
• Familiarity with common security tools and workflows (any of the following): SIEM (Splunk/Elastic/Sentinel), EDR (CrowdStrike/Defender), ticketing (Jira/ServiceNow), basic SOAR concepts.
• Strong written communication: produce clear, escalation‑ready tickets and timelines.
• Ability to work rotating shifts/on‑call (as required), including weekends/holidays depending on coverage model.

Nice To Have (Preferred)

• Cloud security exposure (AWS/GCP/Azure): CloudTrail/Activity Logs, IAM analysis, detections for token/key misuse.
• Familiarity with incident response frameworks/processes (e.g., NIST incident response guidance).
• Exposure to detection engineering concepts (rule tuning, false‑positive reduction), or basic scripting (Python/Bash) for investigation automation.
• Knowledge of the digital‑asset ecosystem (exchanges, custody concepts, operational risk in 24/7 trading environments).
• Certifications (optional): Security+, Blue Team Level 1, SSCP, or equivalent practical training.

What Success Looks Like (First 60–90 Days)

• Consistently accurate triage decisions with strong documentation and clean escalations.
• Reliable shift handovers and measurable reduction in re‑opened or incomplete cases.
• Clear recommendations for detection/playbook improvements based on recurring patterns.
