Intermediate Security Engineer, Security Incident Response Team (SIRT)

An overview of this role

As an Intermediate 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. This role operates on a compressed 4-day work schedule, with a full-time week's hours condensed into four longer working days. Shifts run Sunday through Wednesday to provide 24/7/365 security coverage.

Your primary focus will be detecting and responding to security incidents during your scheduled shifts. You'll work extensively with our incident response automation tools to investigate, analyze, and resolve security events. You'll also have opportunities to contribute to our security tooling and automation, helping to improve our detection and response capabilities.

In this role, you'll develop expertise using our security infrastructure to monitor for threats, analyze potential incidents, and coordinate response efforts across teams. This position is ideal for someone who wants to grow their incident response skills while working within GitLab's established security framework. You'll learn to think both tactically and strategically about security, while getting hands-on experience handling real-world incidents.

Successful Security Engineers thrive in high-pressure environments, remaining calm while following prepared runbooks and thinking critically about security challenges. In this role, you will learn to think like both an attacker and defender, developing proactive and preventative security measures to keep GitLab and its users' data safe in our ever-changing threat landscape. Through hands-on experience and mentorship, you'll develop the skills needed to anticipate security risks, respond effectively to incidents, and contribute to GitLab's robust security posture.
