Security Administrator

ABOUT THE ROLE

We're expanding our security team with a Security Administrator / SOC Analyst. You'll be the front line of Posh's day-to-day security operations: triaging alerts, hunting for threats and anomalies in log data, managing our security tooling, and fielding security questions from teams across the company.

This hire reflects Posh's continued investment in security as we scale. Working alongside senior security staff who will provide support and mentorship, you'll take point on daily security operations while contributing to strategic initiatives — expanding our threat hunting and detection capabilities, assisting in our compliance program, and supporting our SOC 2 audits. If you're an early-career security professional looking for broad exposure to security operations, compliance, and IT at a growing AI company, this is a role where your work is visible, your impact is immediate, and you'll learn directly from experienced practitioners.

Monitor, triage, and respond to alerts; tune existing detections and assist in building new detection rules and dashboards with guidance from senior security staff; and help manage log ingestion sources across the organization

- Administer, configure, and troubleshoot the broader CrowdStrike platform — including endpoint protection/anti-virus and cloud security (CSPM) components — to ensure continuous coverage across the organization

- Serve as the first point of contact for day-to-day security questions from employees

- Assist with compliance team efforts, including evidence gathering and controls support for SOC 2 audits
