About the role
Our Purpose 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.
About Us 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. SentinelOne is building a new AI Platform team whose mission is to accelerate AI feature delivery across the company while ensuring every AI feature meets our security, cost, and quality standards. We are looking for a Principal Engineer to be the founding technical leader of this team: you will partner directly with
the team's engineering leader to define the technical vision and roadmap for the platform that every AI-powered capability at SentinelOne will build on. SentinelOne already ships AI at scale - from our patented detection models to Purple AI, our industry-awarded generative AI security analyst - and your challenge is to turn these proven but distributed capabilities into one coherent platform: deciding what to reuse, what to rebuild, and what to create new. This role is as much about product as it is about platform: you should be able to build AI experiences customers love, and then platformize what was built into capabilities that every team can reuse. If you want your technical judgment to set the direction of AI at a leading cybersecurity company, this is a role for you. What Will You Do? Primary
