About this Senior Enterprise Security Engineer role at Navan

Navan · Onsite · Tel-Aviv, Israel

As a Senior Enterprise Security Engineer, you will be a foundational architect of our corporate security posture, directly safeguarding our infrastructure, sensitive data, and global workforce. This is a highly hands-on, configuration-driven role focused on hardening our environment through identity governance, endpoint security, and automated threat response.

What You’ll Do

  • Identity & Zero Trust: Architect robust IAM principles (Okta, Entra ID) and Zero Trust strategies. Enforce granular authentication, lifecycle management, and device trust to ensure secure access across all corporate resources.
  • Endpoint Security & Fleet Hardening: Lead the administration of our EDR (CrowdStrike Falcon) and MDM/UEM (Intune, Jamf). Manage patch lifecycles, endpoint state attestation, and proactive threat hunting to neutralize threats across all corporate devices.
  • Threat Detection & Automation: Develop advanced detection logic (SIEM/XDR) and build SOAR workflows to reduce Mean Time to Detect (MTTD) and Respond (MTTR).
  • SaaS Security & DLP: Secure our ecosystem by managing email security (e.g., Material Security) and implementing Data Loss Prevention (DLP) across SaaS platforms (Google Workspace, Salesforce, Box).
  • Cross-Functional Leadership: Partner with Engineering and IT to embed security-by-design, automate compliance checks for new infrastructure, and manage security integration for mergers and acquisitions.

What We’re Looking For

  • Experience: 5+ years in corporate security engineering within high-growth, cloud-native environments.
  • Identity Expertise: Expert-level proficiency with Okta (SSO, MFA, IGA) and experience with federation protocols (SAML, OIDC, SCIM).
  • Endpoint/Device Security: Deep hands-on experience with EDR (CrowdStrike) and MDM solutions (Intune, Jamf).
  • Automation: Strong track record of automating security workflows using SOAR or scripting (Okta Workflows, Python, etc.) to drive efficiency.
  • Technical Breadth: Proficiency in Zero Trust models, SaaS/Cloud security, and vulnerability management.
  • Soft Skills: Proven ability to translate complex technical risks into business context and collaborate effectively across technical and non-technical teams.

ABOUT TRIPACTIONS

TripActions is the fastest-growing corporate travel platform disrupting a $1.5T industry and shaping the future of business travel.

TripActions is a story of inspiration born of frustration. Road warriors and co-founders Ariel Cohen and Ilan Twig believed that companies deserved a travel solution that takes the pain out of work trips –– so that their travelers can focus on being productive and meeting in-person, not wasting valuable time booking travel. So in 2015, they created TripActions. Since then, we’ve been a mission to power the face-to-face, in-person connections that move people, ideas and businesses forward.

TripActions’ platform offers a vast selection of inventory that travelers can choose from, a personalized, intuitive user interface driven by machine learning, and 24/7 proactive real human, customer support. Companies enjoy complete travel program visibility, over 30% cost savings on average and seamless integrations with their HR and expense systems.

Globally, TripActions has grown to over 600 employees across 7 offices in 4 countries. We support over 1,500 customers, with innovative brands like Lyft, Dropbox, Sara Lee Frozen Bakery, Allbirds, Robinhood and the ACLU relying on TripActions for their business travel needs. As one of Silicon Valley’s newest “unicorns”, TripActions has a valuation north of $1B and a total of $232M in funding. We’ve recently received $154M in our Series C funding round –– led by new investor Andreessen Horowitz, with participation from repeat investors Lightspeed Venture Partners, Zeev Ventures and SGVC.

TripActions was recently recognized as one of Fast Company’s Most Innovative Companies for 2019, #12 in LinkedIn’s Top Startups 2018 and #3 in the U.S. for Happiest Employees by Comparably.

We’re redefining what it means to travel for work. Come help us build the future of business travel.
