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.\nAbout Us \nSentinelOne 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.\nOur 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.\nWhat Are We Looking For?\nWe’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.\nAs an Offensive Security Researcher, you will be tasked with proactively researching the newest and most sophisticated attack techniques and working closely with some of the best security researchers in the industry to shape the future of cyber security. You will bring curiosity, persistence, and a drive to leave no stone unturned in the search for the next bypass. By being part of our team, your work will impact protection of tens of millions of customer endpoints worldwide, incl. 4 of Fortune10 and hundreds of Global2000, and you will have a chance to work on a industry-leading endpoint security product (recognized 6x in-a-row as Gartner Leaders, scoring highly in Mitre Att&ck, in Frost Radar, SE Labs and by others).\nWhat Will You Do?\nPrimary responsibilities include:\nProactively research and deeply understand the internals of the newest and most sophisticated attack techniques and exploits, and emulate these attacks to assess and improve our detection engines (incl. designing detections and writing behavioural detection signatures).\nBuild tools to support detection assessments, create proofs of concept for the newest techniques and exploits, and develop automation flows to automate unconventional attacks and offensive frameworks.\nWork closely with the Threat Intelligence team and the research and engineering detection teams to provide guidance and highlight gaps in detection and visibility capabilities.\nWhat Skills and Knowledge Will You Bring?\nIdeal candidates will have:\n4+ years of experience in Red Teaming / Security Research / Offensive Research with a deep understanding of Windows internals.\nHands-on experience with coding in Python and C/C++.\nDeep understanding of the malware world (how malware operates, infamous families, evasion and exploitation techniques).\nExperience in malware analysis (statically and dynamically) and reverse engineering (x86/x64)\nUnderstanding of existing EDRs internals.\nExperience writing detection signatures.\nExperience leveraging agentic AI workflows for malware analysis and detection engineering tasks (reverse engineering, code auditing, signature writing).\nProven track record of conference speaking at security conferences or publications is an advantage\nWhy SentinelOne?\nAI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself.
