About The Position

We are looking for someone to join our global cybersecurity team. We are a highly effective team that works to protect and defend against intrusions into Trek's systems. The Information Security Engineer owns two of the security program's most operationally critical functions: Identity & Access Management (IAM) and Security Operations (SOC). This is a senior individual contributor role — you won't manage people, but you will own the technical controls that govern who can access Trek's systems and how threats against those systems are detected and contained. You will be the hands-on owner of Trek's identity infrastructure — Microsoft Entra ID, privileged access, joiner-mover-leaver processes, and access governance — while simultaneously operating as Trek's primary security analyst: monitoring for threats, investigating incidents, and running detection and response workflows across CrowdStrike Falcon, Zscaler, and Microsoft Sentinel. This role demands both the precision of an IAM engineer and the instincts of a SOC analyst. You will work closely with the Director of IT Security and collaborate cross-functionally with IT, HR, Legal, and engineering teams across Trek's global environment. If you want a role where no two days are the same, where you own real enterprise security infrastructure, and where the work you do directly protects a globally recognized brand — this is it. At Trek we view artificial intelligence as a competitive advantage and a personnel multiplier, not a replacement for human expertise or judgment. Our Security team is expected to actively leverare AU tools to increase efficiency and sharpen analysis. Specific AI released tasks will include: Using AI to analyze access patterns and entitlement data at scale — identifying over-provisioning, dormant accounts, anomalous permission combinations, and least-privilege violations across large user populations Applying AI to accelerate alert triage, reduce noise, and surface high-confidence detections across SIEM and EDR platforms Leveraging AI to enrich threat intelligence, correlate indicators of compromise (IOCs), and contextualize threats against Trek's environment Using AI to draft and refine IAM policies, role definitions, access request templates, incident response playbooks, and governance documentation Employing AI coding assistants to automate JML workflows, build security integrations, and maintain detection and reporting pipelines Continuously evaluating new AI-driven security capabilities and recommending adoption where they meaningfully reduce risk or analyst toil

Requirements

5+ years' experience in IT or information security, with demonstrable hands-on ownership across both IAM and security operations functions
Deep hands-on experience with Microsoft Entra ID (Azure AD) including SSO, MFA, Conditional Access, and directory operations
Strong understanding of IAM concepts: RBAC, least privilege, PAM, JML processes, access certification, and federated identity
Experience with endpoint detection and response (EDR) platforms — CrowdStrike Falcon strongly preferred
Experience with SIEM platforms for alert monitoring, investigation, and detection rule management — Microsoft Sentinel preferred
Experience with network security monitoring and proxy platforms — Zscaler ZIA/ZPA preferred
Demonstrated ability to own incident response end-to-end: triage, investigation, containment, eradication, and documentation
Strong understanding of Windows and nix systems, network architecture and protocols (TCP/IP, DNS, HTTPS), and cloud technologies
Demonstrated ability to incorporate AI tools into security workflows — not just awareness of them
Excellent written and verbal communication skills — able to explain identity risk and security incidents to non-technical stakeholders
Holds or is actively pursuing relevant certification: (ISC)² CISSP/CCSP/SSCP; SANS GIAC GCIH/GCIA/GCFA; Microsoft SC-300; CompTIA Security+; or equivalent

Nice To Haves

Experience with privileged access management platforms (CyberArk, BeyondTrust, Admin by Request, or similar)
Scripting experience — PowerShell or Python — for automating identity workflows, detection pipelines, and security integrations
Experience with physical security systems (access control, CCTV) as a secondary function
Experience supporting compliance frameworks — PCI DSS, ISO 27001, SOC 2, or similar — with technical evidence and control documentation
Experience with threat hunting methodologies and hypothesis-driven investigation
Bachelor's degree in Computer Science, Information Security, MIS, or equivalent experience

Responsibilities

Own the IAM program lifecycle: identity governance, role-based access control (RBAC), access certification, joiner-mover-leaver (JML) processes, and policy enforcement
Administer and optimize Microsoft Entra ID (Azure AD) including SSO, MFA, Conditional Access policies, and directory health
Design and maintain a least-privilege access model across SaaS, cloud, and on-premises systems, including privileged access management (PAM)
Drive access certification campaigns: scope, execute, and report on periodic entitlement reviews across all systems
Develop and enforce IAM policies, standards, and procedures — including third-party and service account governance
Detect and investigate identity-based threats: anomalous authentication, lateral movement indicators, credential abuse, and over-privileged account activity
Partner with HR, IT, and application teams to ensure processes are accurate, automated where possible, and consistently enforced
Support audit and compliance activities with identity evidence and access control documentation
Serve as Trek's primary security analyst: monitor alerts across CrowdStrike Falcon, Microsoft Sentinel, and Zscaler; triage, investigate, and escalate as warranted
Own the incident response lifecycle for security events — from initial detection through containment, eradication, recovery, and post-incident review
Develop, tune, and maintain detection rules and correlation logic across SIEM and EDR platforms to reduce noise and surface high-confidence detections
Build and maintain incident response playbooks, investigation runbooks, and post-incident documentation
Integrate identity signals and IAM data into SOC detection workflows — connecting the IAM and SOC functions into a unified threat detection capability
Conduct threat hunting using CrowdStrike, Sentinel, and Zscaler telemetry to proactively identify attacker activity that evades automated detection
Orchestrate and automate security operations workflows to improve speed and consistency across the security team
Evangelize information security practices within Trek worldwide
Perform other duties as assigned
