About the Role

Serve as the technical lead for the incident response lifecycle, driving the containment and remediation of security threats across multi-cloud infrastructure, products, and operational environments. Balance hands-on technical investigations with leadership to coordinate response efforts, leveraging a modern security stack to protect a global travel and expense platform.

Responsibilities

  • 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.
  • Use Tines to build and design workflows that automate triage, enrichment, and containment actions.
  • Manage and fine-tune detection rule lifecycles utilizing CrowdStrike EDR and SIEM/SOAR capabilities.
  • 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.
  • Partner with infrastructure owners to ensure new systems ship with the right telemetry, encryption, authentication, and response playbooks.
  • Evaluate and design response strategies for frontier security concerns.
  • Actively participate in the scheduled Incident Response on-call rotation.

Requirements

  • 5+ years of experience in a dedicated Incident Response, SOC, or Security Engineering role.
  • 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.
  • Ability to coordinate cross-functional teams (Engineering, Legal, PR).
  • Ability to clearly communicate complex technical risks to stakeholders.
