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.\nAt Prompt Security, our mission is to empower organizations to safely harness the transformative power of Generative AI. As a one-stop security platform, we provide visibility, governance, and real-time protection against all Generative AI concerns, enabling organizations to innovate and prosper in the age of AI without compromising on security.\nAs a Staff Endpoint Software Engineer, you'll design and build the low-level security sensors and enforcement engines that sit at the heart of our Generative AI Security platform - running deep inside endpoints, browsers, and production workloads to detect and stop threats in real time. You'll own critical architecture decisions, work hands-on with OS internals (kernel-level hooks, system calls, process/network monitoring), and set the technical bar for how we build secure, lightweight agents at scale. This is a high-ownership role for engineers who love working close to the metal and want their code protecting real enterprise environments from day one.\nWhat Will You Do?\nArchitect and continuously optimize sensor components for minimal system footprint, high performance, low resource consumption, and maximum reliability.\nDrive the technical evolution of our AI Security Posture Management (Agentic) engine - designing adaptive policy logic, improving decision engines, and expanding platform coverage.\nBuild and own endpoint security solutions (macOS & Windows), integrating deeply with OS-level APIs for real-time threat detection and data protection.\nSet technical direction and mentor engineers on best practices for building secure, high-performance, low-level system components.\nPartner closely with security researchers, QA, and product teams to translate emerging threats into shipped protection.\nStay ahead of the latest developments in Generative AI security and OS-level threats, bringing new techniques into our agents and extensions.\nWhat Skills and Knowledge Will You Bring?\n6+ years of experience in Python, Node.js, or a comparable language, with deep hands-on work at the OS/systems level\nStrong experience with macOS and/or Windows Endpoint Security frameworks (e.g., EndpointSecurity.framework, ETW, minifilter/kernel drivers)\nDeep understanding of OS architecture and internals (processes, system calls, memory, file system, networking stack)\nTrack record of owning complex, low-level systems from design through production at scale\nExcellent problem-solving skills, strong technical judgment, and attention to detail\nExperience with browser extension development (Chrome, Firefox, etc.) - Advantage\nWhy us?\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. If you want to build where innovation and impact move together, this is that place.We invest in our Sentinels with comprehensive, competitive benefits designed to support you and your family:\nEquity & Rewards \n\nRestricted Stock Units (RSUs)\nEmployee Stock Purchase Plan (ESPP)\nTime Off & Wellbeing\n\nCompetitive leave benefits\nGender-neutral parental leave\nEmployee Assistant Program\nWorkout sessions and a Wellness App\nInsurance & Financial Security \n\nMedical and insurance benefits\nPension\nEmployee Assistance Program (EAP)\nWork Perks & Flexibility \n\nGlobal home office allowance\nMobile phone reimbursement\nSentinelOne is proud to be an Equal Employment Opportunity and Affirmative Action employer.
