As a Senior Security Engineer on GitLab's Security Incident Response Team (SIRT), you will be on the frontline of protecting both GitLab.com and GitLab the company from security threats.

You will lead high-impact incidents and investigations, drive continuous improvements in defense, detection and response capabilities, and help scale security operations through automation and intelligent workflows.

Operating within a 24/7 global environment (follow the sun model), you will own incidents end-to-end - from detection and triage through containment, eradication, and recovery - while partnering cross-functionally to strengthen GitLab’s overall security posture. A key aspect of this role is leveraging automation and AI-driven approaches to improve detection fidelity, accelerate investigations, and reduce response times. You will help shape how modern tooling and data are applied to stay ahead of evolving adversary tactics.

This role is ideal for someone who thrives in high-tempo environments, brings strong DFIR expertise, and is equally passionate about operational excellence and building scalable detection and response systems and workflows.
