About the role

  • You will join the growing Detection Engineering team at GitLab, responsible for building and maintaining a best-in-class detection engineering program.
  • If you love writing threat detections, hunting for patterns of behavioral anomalies across corporate, cloud, and customer environments as well as closing detection gaps, this team is for you.

Responsibilities

  • Identify MITRE ATT&CK/top threat actor detection gaps and write behavioral detections to close them.
  • Be a detection SME and deeply understand GitLab’s detection methodology, DaC framework, detection types, and quality thresholds.
  • Act as a “detection architect” - orchestrating agents across the entire detection lifecycle and ensuring detection quality and consistency.
  • Use a SIEM/data lake platform like Splunk or Elastic to write and troubleshoot threat detections.
  • Collaborate with peer GitLab teams to identify and close security observability improvement opportunities.
  • Collaborate with incident response, red team, as well as threat intelligence to cross functionally improve GitLab’s detection program and coverage.
  • Use, maintain, and build new DaC, AI, and process efficiency automations for the signals engineering program.

Requirements

  • SOC, incident response or detection engineering expertise.
  • SIEM/security data lake detection and query expertise.
  • A proven ability to proactively detect potentially malicious patterns and collaborate with incident response to complete incident RCAs to identify and implement new detection opportunities.
  • Strong Cloud (AWS/GCP) and some PaaS (Kubernetes/terraform) experience.
  • Experience orchestrating teams of agents to write detections.
  • Bring a passion for deep dive threat hunting and cross functional purple teaming and turning results into detections.
  • Experience with mature detection capabilities such as: Detections as Code, Signal vs detection development, risk based alerting, and behavior analytics.
  • Due to government requirements, you must be a United States Citizen (defined as any individual who is a citizen of the United States by law, birth, or naturalization) to fill this position.

Preferred qualifications

  • Bonus points if you are experienced in writing SaaS application detections, double bonus points if that application is GitLab.
  • An understanding of the GitLab application, bonus points if you are comfortable detecting and hunting for attacks against GitLab or if you’ve maintained GitLab yourself.
  • Bonus points for experience building full end to end agentic detection pipelines.
