About the Role

Fluidstack is building civilization-scale infrastructure for AI, delivering gigawatt-scale compute faster than anyone else. We are seeking individuals who care deeply about this mission and want to contribute to the frontier of AI.

Responsibilities

  • Build the detection engineering function from the ground up, including telemetry pipelines, detection content, alert routing, and response runbooks.
  • Own detection-as-code end to end, writing detections across cloud and endpoint sources with tests, version control, and CI.
  • Lead incident response for high-severity events, driving containment and root cause analysis.
  • Drive automation of triage and enrichment in Python or similar languages.
  • Partner directly with leadership on security strategy, translating threat landscape and detection gaps into a prioritized roadmap.
  • Work across corporate IT and infrastructure teams to obtain necessary telemetry, logging, and access, and to address root causes identified through detections.

Requirements

  • 8+ years in security operations, detection engineering, or incident response, with experience at a high-growth tech company, cloud-native infrastructure provider, or top-tier MDR/threat intel firm.
  • Proven experience building or scaling a detection engineering function.
  • Deep hands-on experience writing detections against cloud telemetry (AWS, GCP, or Azure) and endpoint telemetry.
  • Strong scripting and automation skills in Python or similar.
  • Incident response experience at a company operating at significant scale, including leading response under pressure.
  • Ability to operate as a technical lead, setting direction and executing work.
  • Ability to work effectively across corporate IT and infrastructure teams in a fast-moving environment.
  • Experience securing GPU clusters, HPC environments, or physical data center infrastructure is a plus.
  • Contributions to open-source detection content (Sigma, community rule sets) is a plus.
