Jobs Companies Navan Sr. Security Engineer, Incident Response

About this Sr. Security Engineer, Incident Response role at Navan

Navan · Onsite · Austin, TX
At Navan, you will serve as the technical lead for our incident response lifecycle, driving the containment and remediation of security threats across our multi-cloud infrastructure, products, and operational environments. You will balance hands-on technical investigations with the leadership required to coordinate response efforts, leveraging a modern security stack to protect our global travel and expense platform.

What You’ll Do:
  • Incident Response Leadership: Act as the primary Incident Lead during high-severity events. Own the end-to-end response lifecycle: driving triage, containment, evidence capture, and post-incident root-cause analysis.
  • Automation & SOAR Engineering: Use Tines to build and design workflows that automate triage, enrichment, and containment actions, significantly reducing operational toil and improving time-to-contain.
  • Detection & Endpoint Monitoring: Manage and fine-tune detection rule lifecycles utilizing CrowdStrike EDR and SIEM/SOAR capabilities to maintain high-precision, low-latency coverage against modern adversary tradecraft.
  • Data Protection & Visibility: Monitor and respond to data risks across endpoints, identity, and SaaS applications using Cyberhaven DLP. Identify gaps in IAM and vulnerability management and advocate for direct fixes.
  • Architecture Partnership: Partner with infrastructure owners to ensure new systems ship across all cloud environments with the right telemetry, encryption, authentication, and response playbooks from day one.
  • Emergent Threats: Evaluate and design response strategies for frontier security concerns, such as automated agents or bots operating across infrastructure at scale.
  • On-Call Rotation: Actively participate in the scheduled Incident Response on-call rotation, ensuring reliable coverage and operational readiness for emergent threats.

What We’re Looking For:

  • 5+ years of experience in a dedicated Incident Response, SOC, or Security Engineering role, with a proven track record of leading high-severity incident containment in fast-paced environments
  • Strong familiarity with the MITRE ATT&CK framework, modern adversary tactics, techniques, and procedures (TTPs), and common attack vectors targeting SaaS platforms
  • Proven experience managing and tuning detection logic within CrowdStrike Falcon (or equivalent enterprise EDR/XDR) and enterprise SIEM platforms.
  • Excellent leadership skills with the ability to remain calm under pressure, coordinate cross-functional teams (Engineering, Legal, PR), and clearly communicate complex technical risks to stakeholders.

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.
