TL;DR · Security Research Analyst, WAF Managed Rules

The Security Research Analyst, WAF Managed Rules joins the team responsible for researching web application attacks and developing protections within the Web Application Firewall. This role involves analyzing public CVEs, threat intelligence, and internal telemetry to identify exploitation patterns and develop mitigations. You will design, test, and deploy managed rules and exploit signatures while investigating false positives to minimize disruption to legitimate traffic. Key responsibilities include reproducing exploits in controlled environments, performing targeted penetration testing, and building research tools to automate validation. You will utilize SQL to investigate large datasets and languages such as Python, Go, or Rust for automation. The work focuses on the detection lifecycle, addressing common vulnerability classes like SQL injection, cross-site scripting, and remote code execution to protect internet properties from emerging exploits.

What you'll do

  • Analyze public CVEs, proof-of-concept exploits, and observed attacks to identify root causes and mitigation opportunities.
  • Design, test, and deploy WAF managed rules and exploit signatures to protect against evolving threats.
  • Investigate customer reports and telemetry to reproduce issues and refine detections while minimizing false positives.
  • Perform targeted penetration testing and adversarial testing to identify detection gaps and evaluate mitigation resistance.
  • Build tools and automated test cases to accelerate exploit analysis, rule validation, and regression testing.
  • Use SQL and production data to measure rule efficacy, track attack trends, and assess performance.
  • Document technical findings and mitigation decisions for internal research reports and public-facing blogs.

What we're looking for

  • You have hands-on experience in web application security, vulnerability research, or detection engineering.
  • You have experience writing and improving WAF rules, exploit signatures, or comparable detection logic.
  • You understand HTTP/HTTPS, web application/proxy request processing, and common vulnerability classes like SQLi, XSS, RCE, SSRF, and insecure deserialization.
  • You can analyze vulnerability advisories, reproduce exploits in controlled environments, and identify request characteristics distinguishing exploitation from legitimate traffic.
  • You use SQL to investigate large datasets and a language such as Python, Go, or Rust to build research tools and automate analysis.
  • You can communicate technical findings clearly to both technical and non-technical audiences.
  • You use AI fluently in research and coding workflows with the judgment to independently validate outputs.
  • Export control laws, including the U.S. Export Administration Regulations.
