We are hiring Security Analysts to run the daily security operations work that keeps Nscale protected.

This is a hands‑on analyst role, one level below Staff, working across alert triage, incident investigation, escalation, evidence collection, response coordination, vulnerability follow‑up, and operational reporting. The role connects closely with Incident Response, Cyber Defence, Enterprise Security, IT, Platform Engineering, identity, endpoint, vulnerability management, network security, GRC, and platform teams.

Security operations is where controls become real. This role helps ensure security events are investigated consistently, incidents are escalated quickly, and daily operational risks do not get lost in the noise.

• Produce daily and weekly operational reporting covering alert volumes, true positives, escalations, open cases, recurring issues, and response SLAs.
• Improve runbooks, investigation guides, alert tuning feedback, and automation opportunities.
• Identify recurring false positives, missing context, or weak handoff points and propose fixes.
• Follow up on vulnerabilities and exposures where daily operations identifies active risk, missing ownership, or overdue remediation.

• Build fluency across the core telemetry sources used for endpoint, identity, SaaS, cloud, and infrastructure investigations.
• Triage and document daily alerts with clear findings, confidence level, and recommended next action.
• Improve at least three runbooks or investigation guides based on real operational friction.
• Support at least one tabletop, incident review, or readiness exercise.
