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.

You will bring deep front-end and back-end expertise to drive this product from technical design through delivery, integrating it with our existing platform and collaborating closely with product, security, and other engineering teams. This is an opportunity to leverage modern technologies and help revolutionize how we defend against threats.\nWhat Will You Do?\nPrimary responsibilities include:\nLead the design, development, and testing of SentinelOne's next generation security orchestration and automation (SOAR) tools, taking features from technical design through delivery with minimal guidance.\nIntegrate the SOAR solution with our existing product offering to extend the value of SentinelOne's cybersecurity platform, working through moderately complex technical challenges independently.\nCollaborate closely with cross functional teams, including product, security, and other engineering teams, acting as a technical resource for the SOAR product area.\nWork across the full stack, including React, TypeScript, Python (FastAPI with SQLModel), and NodeJS for the front end and services layer, Codemirror and Reactflow for the product's workflow building experience, and PostgreSQL, Docker, Kubernetes, Redis, AWS, and GCP for the underlying infrastructure.\nWhat skills and knowledge should you bring?\nIdeal candidates will have:\n6 or more years of professional full stack or front end engineering experience\nExtensive coding experience in TypeScript using React, with the depth to independently lead design and implementation of complex front end systems.\nPrevious coding experience building backend APIs in Python - advantage.\nAbility to mentor and act as a technical resource for colleagues with less experience.\nExperience with Codemirror or Reactflow is preferred.\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.
