About the role
As a Senior Enterprise Security Engineer, you will be a foundational architect of Navan’s security posture, directly safeguarding our corporate infrastructure, sensitive financial data, and global user base. This is a highly hands-on, configuration-driven role that requires working directly with systems that power our security program in a modern, cloud-native environment.
Your work will be critical in ensuring Navan becomes globally recognized for secure, unparalleled corporate travel and expense management.
What You’ll Do:
•
Vulnerability Management & Exposure Reduction: Architect, manage, and scale the end-to-end vulnerability management program. Oversee continuous asset discovery, vulnerability scanning, threat exposure assessment, and risk-based prioritization (CVSS, EPSS, threat intelligence). Partner closely with infrastructure, engineering, and IT teams to establish SLAs, streamline patch management workflows, and validate effective remediation.
•
Security Incident Response & On-Call Rotation: Participate in the security engineering on-call rotation. Serve as a responder responsible for identifying, scoping, triaging, managing, and mitigating security incidents, followed by leading thorough post-incident reviews and root-cause analyses.
•
Detection & Automation Optimization: Help improve and maintain our existing detection pipeline by providing feedback on alert quality, reviewing current monitoring coverage, and performing direct tuning in SIEM platforms to reduce noise and increase signal fidelity. Evaluate existing SOAR playbooks and workflows, offering recommendations and performing targeted updates to streamline response processes.
•
Identity Governance & Access Control: Define and enforce strong IAM principles (e.g., Least Privilege, Zero Trust) and contribute to identity governance platforms to ensure secure authentication, authorization, and access across the enterprise.
•
Email Security: Strengthen email security by managing alerts and workflows in platforms like Material Security, reviewing post-delivery threats, and improving automated response to suspicious messages and mailbox activity.
•
Cross-Functional Security Leadership: Proactively partner with Engineering, IT, and Compliance teams to embed security best practices early in the lifecycle, align vulnerability SLAs with business risk objectives, and foster a culture of shared security ownership.
•
Process Improvement & Metrics: Establish and track key performance indicators (KPIs) for vulnerability management and incident response. Participate actively in incident and posture reviews, drive continuous operational improvements, and work with external vendors to align system capabilities and security expectations.
What We’re Looking For:
•
5+ years of hands-on experience in information or enterprise security, preferably within a high-growth tech environment utilizing cloud infrastructure.
•
Proven track record of designing, implementing, or maturing an enterprise-wide Vulnerability Management program, including expertise with modern exposure management and scanning platforms (e.g., Tenable, Qualys, Rapid7, Wiz) and vulnerability remediation workflows.

•
Deep, up-to-date knowledge of modern attacker tactics, techniques, and procedures (TTPs), common exploit vectors, and risk prioritization frameworks (CVSS, EPSS, KEV). You excel at translating technical vulnerabilities and risks into clear business context for a range of stakeholders.
•
Ability to review SIEM and EDR/XDR platform outputs, provide constructive feedback on detection efficacy, and execute direct rule tuning and configuration refinements to optimize signal-to-noise ratio.
•
