Corporate Security Engineer

Branch is a fintech company on a mission to empower workers with financial freedom by providing accessible financial services. The Corporate Security Engineer will manage endpoint security and insider risk programs, ensuring the safety of corporate identities and devices from threats while collaborating with various teams to implement security policies and respond to incidents.

Responsibilities:

• 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
• 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 our IAM team
• Triage and investigate insider risk cases with discretion, partnering with Legal, HR, and GRC on documentation, evidence handling, and outcomes; preserve chain-of-custody on every case
• Develop user-facing guidance and training that reduces accidental risk — phishing reporting, secure handling of customer data, and acceptable use of AI and SaaS tools
• Harden Google Workspace — admin role hygiene, context-aware access, OAuth third-party app governance, advanced phishing/malware protection, and audit logging into the SIEM
• Automate repetitive corporate security work using Python or Bash and orchestration platforms (e.g., Tines, Torq, XSOAR) — alert enrichment, user notifications, evidence collection, and offboarding checks
• Contribute to the corporate vulnerability management program for endpoints and SaaS — prioritization, SLA tracking, and cross-functional remediation
• Serve as a security consultant and escalation point for the broader business on secure configurations, patching, exception requests, and acceptable-use questions

Requirements:

• 3–5 years of experience in a corporate security, endpoint security, security operations, or insider risk role with increasing responsibility
• Hands-on experience with EDR — ideally CrowdStrike Falcon — including detection tuning, custom IOAs/IOCs, and Real Time Response investigations
• Working experience with application control or zero-trust endpoint tooling (ThreatLocker, Airlock, AppLocker, or equivalents) — you understand the operational reality of allowlisting at scale
• Familiarity with enterprise / managed browsers (Island, Talon, Chrome Enterprise) and the data-egress and SaaS access controls they enable; comfort designing browser policy is a strong plus
• Strong Google Workspace security background — admin console controls, context-aware access, OAuth governance, and DLP
• Demonstrated ability to investigate incidents end-to-end — phishing, malware, account compromise, DLP events, and insider risk cases — with disciplined documentation
• Solid fundamentals in identity and access management, endpoint hardening, MDM, logging, and SIEM-based detection
• Scripting proficiency in Python and/or Bash for automation and tooling; experience with security orchestration platforms (Tines, Torq, XSOAR) is a plus
• Strong written and verbal communication — able to explain endpoint and insider risk concepts to non-security partners in HR, Legal, and the executive team
• Strong ethics and discretion — this role regularly handles confidential personnel and investigative information
• Familiarity with security frameworks such as ISO 27001, SOC 2, PCI-DSS, NIST CSF, and CIS Benchmarks
