Staff AI Security Researcher

At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future. As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.

• Conduct advanced research to identify vulnerabilities within AI (LLMs, SLMs) models, agentic systems and their infrastructure, including prompt injection, jailbreaking, data exfiltration, and misuse vectors.
• Build threat models for emerging AI capabilities and deployment surfaces (agents, tool use, multimodal systems).
• Innovate and design novel methodologies and automated tools to systematically and continuously probe AI security mechanisms at scale.
• Partner with engineering and product teams to translate research findings into our Agentic Detection and Response offering.
• Stay informed on the latest academic, industry and threat landscape trends on adversarial ML, agentic and AI security.
• Mentor other researchers and engineers and help grow the team's technical capabilities.
• Publish research findings internally and externally through papers, blog posts, or industry conferences.

What Skills and Knowledge Will You Bring?

• 6+ years of experience in offensive research, red teaming or pentesting, with focus on AppSec or Identity.
• Hands-on experience with adversarial techniques against AI (LLMs, SLMs) and ML systems - prompt injection, jailbreaking, membership inference, model extraction, data poisoning, etc.
• Good understanding of identity/access management (IAM) protocols and tools.
• Familiarity with agentic attack taxonomies such as OWASP Top 10 for LLMs and MITRE ATLAS.
• Proficiency in programming and scripting languages (Python, JavaScript and Java) and Cloud environments (AWS, GCP, Azure, Kubernetes).
• Technical writing & content development skills.
• Publication record or demonstrable body of work in security research, adversarial ML, or AI safety (papers, disclosed vulnerabilities, open-source tools, etc.) - advantage.
• Experience in leading cross-functional technical initiatives - advantage.

Our Purpose

SentinelOne is a company at the intersection of AI and security, pioneering a new operating model for cybersecurity. Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.

Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.

What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Staff AI Security Researcher, you will be tasked with leading efforts identifying and understanding security risks unique to AI systems. Investigate demonstrate attacks - prompt injections, jailbreaks, data leakage, agentic workflow hijacking and architecture/ecosystem flaws (plugins, connectors, MCPs, skills). Translate findings into detections and safeguards, and help build our agentic detection and response capabilities from the ground up.
