About the Company

Fluidstack is focused on delivering massive compute infrastructure for AI. We acquire power, design and build data centers, and operate them, rethinking every layer of the stack to scale civilization-scale infrastructure for AI.

Responsibilities

• Lead detection engineering for Fluidstack's IT surface, including cross-domain detections bridging IT, OT, or physical surfaces
• Author and tune production detections as code using CI/CD and peer review
• Apply AI and machine learning to build behavioral analytics and anomaly detection at scale
• Develop novel detection tooling, including agentic capabilities using LLMs for triage and investigation
• Set engineering standards, coverage methodology, and quality metrics for the detection engineering discipline
• Conduct threat and security research to inform detection logic and close the detection-to-response loop

Requirements

• Experience building and tuning production detections as code measured by precision and recall
• Fluency across SIEM, EDR, and cloud/IT telemetry
• Experience engineering detection pipelines with CI/CD and peer review
• Experience applying ML or behavioral analytics to detection at scale
• Proficiency with LLM-based tooling for triage and investigation
• Ability to define coverage methodology and quality metrics for a detection function
• Experience conducting threat research that drives new detections

Preferred Qualifications

• Experience with detection-as-code frameworks like Sigma or Panther
• Experience with OT or physical-surface detection
• Experience building agentic/LLM security tooling
• Experience building a detection function from the ground up
