• Identify emerging trends, tactics, techniques, and tooling used by adversaries, and articulate their potential impact on customers and verticals.
• Provide actionable findings to detection, product, and engineering teams to improve customer protection and inform AI-driven defense strategies.
• Collaborate with engineering teams developing Proofpoint’s agentic AI solutions, ensuring security considerations are integrated and AI capabilities are leveraged effectively in research workflows.
• Explore and apply modern AI techniques to augment threat research, including clustering, attribution, campaign discovery, and prioritization.
• Occasionally deliver technical briefings to customers, user groups, and internal or external stakeholders.
• Collaborate on research projects with the wider threat research team and cross-functional AI security initiatives.
• Work effectively as part of a global, remote-first team using chat, video, and asynchronous collaboration tools.
Qualifications
• Proven experience in cybersecurity, threat intelligence, incident response, or related fields.
• Strong foundation in threat research, cybercrime, fraud, or adversary-focused security work, with hands-on experience analyzing real-world attacks.
• Well-rounded understanding of the modern threat landscape, including phishing, BEC, account takeover, malware, and other email-borne threats.
• Practical working knowledge of modern AI technologies, including LLM frameworks, agentic AI systems, and AI-assisted tools.
• Experience building or experimenting with simple agentic AI applications leveraging LLM frameworks, MCP servers; AI engineering experience.
• Ability to translate complex technical findings into actionable insights and risk narratives for customers, internal teams, and executives.
• Strong written and verbal communication skills • Collaborative mindset, capable of working closely with detection, product, and engineering teams.
• Participation in the information security community, such as published papers, blogs, conference presentations, or open-source contributions.
