United States — Remote

Nasuni is seeking a Senior Security Operations Analyst to strengthen enterprise security operations across cloud, identity, endpoint, email, and collaboration environments. You will independently lead complex investigations, improve detection quality, mature SOC processes, and turn operational data into measurable gains in detection, containment, and response.

This role is for an experienced, hands-on SOC practitioner who has owned incidents and operational improvements in a distributed enterprise or SaaS environment. It is not an entry-level, GRC-only, or advisory-only position.

You will operate as a senior individual contributor with authority to make incident triage, severity, and escalation decisions within Nasuni ’s response framework. You will own cases from signal through containment, remediation coordination, documentation, and post-incident learning; improve detections, playbooks, dashboards, and procedures; and mentor other analysts. You will influence Security, IT, Cloud, Identity, Engineering, and external providers, while enterprise strategy, company-wide policy, and people management remain outside this role.

Lead advanced investigations across endpoint, identity, cloud, email, SaaS, and network telemetry; determine scope, impact, root cause, containment, and follow-up actions.
