About the role: The Corporate Security Engineer is the dedicated owner of Branch’s endpoint security and insider risk programs. You will be responsible for keeping every Branch laptop, browser session, and corporate identity safe from external threats and inadvertent or malicious misuse — across a fully remote, fintech workforce. In this role, you will operate and continuously mature our core corporate security stack — CrowdStrike Falcon for endpoint detection and response, ThreatLocker for application allowlisting and ringfencing, Island Enterprise Browser for managed web access and data egress controls, and Google Workspace for identity, mail, and collaboration security. You will partner closely with People Operations, Legal, and GRC to translate policy into enforced technical controls, investigate insider risk signals end-to-end, and respond to corporate-side security incidents in a measured, programmatic way. This is the right role for a hands-on engineer who wants to own the corporate attack surface, build the insider risk function from a blueprint into a running program, and have visible impact on how a fast-moving fintech protects its workforce. Responsibilities include, but are not limited to: Endpoint Security & Engineering Own the day-to-day administration of CrowdStrike Falcon — prevention policies, detection tuning, custom IOAs, USB device control, and Real Time Response runbooks across the entire Branch endpoint fleet. Operate and mature ThreatLocker — build and maintain application allowlisting, ringfencing, storage control, and elevation policies; reduce learning-mode exceptions over time and drive measurable hardening progress. Administer Island Enterprise Browser — define and enforce browser-level policies for SaaS access, copy/paste, downloads, screenshot, and extension governance; align browser controls with insider risk and DLP objectives. Drive endpoint hardening and configuration baselines for macOS and Windows. MDM (Jamf / Intune), patch SLAs, FileVault/BitLocker, and CIS-aligned benchmarks. Maintain a defensible inventory of endpoints, agents, and coverage gaps, and drive remediation when devices fall out of compliance. Own corporate-side incident response for endpoint, identity, email, and insider events — from initial triage through containment, eradication, recovery, and post-incident review. Insider Risk & Data Protection Build and run Branch’s insider risk program — from defining risk indicators (data exfiltration, anomalous access, departing employee behavior) to building detections and response playbooks across endpoint, browser, and SaaS telemetry. Operate Data Loss Prevention controls across Google Workspace (Drive, Gmail), Island Browser, and endpoint channels; investigate DLP events end-to-end, balancing user friction against data-protection outcomes. Lead onboarding, offboarding, transitions security workflows in partnership with People Operations — enforce least-privilege access, data return at offboarding, and time-bounded monitoring of high-risk departures, ultimately skilling up
