Overview

As a Security Engineer II – Endpoint Security, you will serve as an independent assurance layer for the security posture of every corporate endpoint — laptop, server, and workstation across Mac, Windows, Linux, and Windows Server — closing the gaps that make privilege escalation and lateral movement possible. You will validate that local administrative rights, endpoint configuration, and installed software match security intent, while directly owning browser/IDE extension governance and the tuning of endpoint security agents. Reporting into the Cyber Threat Intelligence organization, you will work end-user facing issues end to end and partner closely with Desktop Engineering, Identity & Access Management, and Security Operations. An ideal candidate combines solid Enterprise Security fundamentals with practical, cross-platform endpoint engineering and system administration experience.

Responsibilities

• Continuous Endpoint Hardening: Maintain a standing, open-ended mandate to identify and drive endpoint security improvements across the fleet — beyond any fixed checklist.
• Endpoint Sensor Engineering: Administer, tune, and troubleshoot endpoint security agents (CrowdStrike Falcon, DTEX, Zscaler ZDP) across all platforms; continuously tighten CrowdStrike prevention/detection policy and investigate agent alerts, escalating true positives with context.
• Application & Extension Governance: Own the browser/IDE extension review process end to end (risk-scoring, approve/deny/remove) and run recurring automated reviews of installed software to surface unauthorized, high-risk, or end-of-life applications.
• Exception Management: Manage approval, tracking, and reporting of endpoint security exceptions.
• Configuration Assurance & Allow-Listing: Validate Group Policy and registry-level settings against security best practices, and partner with Desktop Engineering to move the fleet to an approved application allow list.
• Extended Tooling & Firmware Exposure: Assist with DSPM, inventory/assess out-of-band management tools and applications.
• End-User Support & Documentation: Serve as the primary technical resource for end-user endpoint security issues, and document standards, runbooks, and best-practice guidance for partner teams.

Qualifications

• 2 years of experience in Information Security, Cyber Security, or Endpoint/Systems Engineering. - Preferred
