About Us At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see signifi

Key Responsibilities

1
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.
2
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.
3
Adversary Simulation: Execution of full-chain red team operations targeting Cloudflare’s global infrastructure, corporate networks, and product ecosystems.
4
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).
5
Purple Teaming: Foster a highly collaborative relationship with the Blue Team (Detection & Response) to ensure findings are translated into immediate defensive improvements.
6
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.
7
Executive Reporting: Translate complex technical exploits into risk-based narratives for leadership, helping prioritize engineering resources where they matter most.

Requirements

Experience: 4+ years in offensive security, application security or other relevant field
Deep knowledge: 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.
Technical Roots: A strong background in manual penetration testing, exploit development, or cloud security (AWS/GCP/Bare Metal).
Operational Mindset: Experience using the MITRE ATT&CK framework to map coverage and identify "blind spots" in defensive telemetry.
Communication Skills: The ability to explain a complex "0-day" exploit to a non-technical stakeholder while maintaining the respect of a deep-dive engineering team.
Tooling Familiarity: Knowledge of automated breach and attack simulation (BAS) tools, as well as custom-built frameworks for payload delivery and C2 infrastructure.
