The AI Security Research & Red Team Engineer will conduct AI-focused security research, agentic and LLM testing, adversary simulations, and efficacy testing to identify vulnerabilities and improve Cloudflare’s security posture. The role also partners with incident response, threat detection, engineering, and governance teams while mentoring others and communicating risk to executives.
Responsibilities
- AI Security and Vulnerability Research: Stay current with emerging threats and perform deep-dive research to identify AI-specific vulnerabilities and risks in addition to general vulnerabilities across Cloudflare’s products and services
- Agentic testing and adoption: As a core function, identifying AI-related attack surfaces through rigorous testing of agentic implementations and LLM usage which will help define requirements and implementation guidance while proactively
- Adversary Simulation: Execution of full-chain red team operations targeting Cloudflare’s global infrastructure, corporate networks, and product ecosystems
- Efficacy Testing: Establish a rigorous framework for testing "Security Efficacy"—measuring exactly how well our WAF, EDR, and SIEM detections perform against known TTPs (Tactics, Techniques, and Procedures)
- Purple Teaming: Foster a highly collaborative relationship with the Blue Team (Detection & Response) to ensure findings are translated into immediate defensive improvements
- Mentorship & Growth: Be a technical leader, providing technical expertise while fostering a culture of curiosity, ethical hacking and partnering to improve Cloudflare’s security posture
- Executive Reporting: Translate complex technical exploits into risk-based narratives for leadership, helping prioritize engineering resources where they matter most
Skills
- 4+ years in offensive security, application security or other relevant field
- Deep knowledge of AI, Coding agents, LLMs, prompt engineering, AI-related attack vectors (e.g., prompt injection, jailbreaking), and Agentic concepts all for use in the red team but also testing Cloudflare uses
- A strong background in manual penetration testing, exploit development, or cloud security (AWS/GCP/Bare Metal)
- Experience using the MITRE ATT&CK framework to map coverage and identify 'blind spots' in defensive telemetry
- The ability to explain a complex '0-day' exploit to a non-technical stakeholder while maintaining the respect of a deep-dive engineering team
- Knowledge of automated breach and attack simulation (BAS) tools, as well as custom-built frameworks for payload delivery and C2 infrastructure
Benefits
- This role is eligible to participate in Cloudflare’s equity plan.
