About the role

Key responsibilities & impact
  • Design and direct AI-assisted, agentic detection workflows at scale, with human quality oversight
  • Author and ship network signatures and detections against internet-scale scan and probe data
  • Identify services, versions, and vulnerable hosts
  • Build detections against Canary telemetry to distinguish real exploitation from internet noise
  • Synthesize exploitation signals into actionable threat intelligence for customers
  • Drive feedback loops into probing and collection capabilities
  • Identify necessary data collection, unnecessary collection, and coverage gaps
  • Evaluate detection quality and tune false-positive and false-negative rates
  • Respond rapidly to high-impact vulnerabilities by analyzing, building coverage, and shipping detections
  • Collaborate with vulnerability researchers and threat hunters to connect detection engineering with exploit intelligence

Requirements

What you’ll need
  • 5+ years of experience building and shipping durable detections over network and host data
  • Experience scaling detection development and continuous evaluation processes using AI and agentic workflows with humans on the loop
  • Track record of researching, engineering, and validating durable detections across network and host telemetry
  • Disciplined approach to false positives and false negatives
  • Expertise in device fingerprinting and protocol analysis
  • Knowledge of attacker command-and-control techniques, covert channels, and exploitation artifacts
  • Experience with network traffic analysis
  • Background in host-based analysis and DFIR
  • Strong programming or scripting ability
  • Familiarity with CVE, NVD, KEV, or exploit intelligence datasets
  • Response mindset toward newly disclosed vulnerabilities
  • Preferred: Experience with Suricata, Snort, Zeek, Nuclei templates, or similar tools
  • Preferred: Published detection research, signatures, or open-source detection content
  • Preferred: Experience with streaming systems or real-time data processing
  • Preferred: Background in high-growth or startup environments
