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 an experienced threat hunter, you will be tasked with delivering SentinelOne’s proactive threat hunting services to our Threat Hunting clients (including FedRAMP-authorized environments). You’ll build and maintain a high-quality library of hunts and rules across Windows, macOS, and Linux, with a strong emphasis on EDR telemetry (bonus if you know SentinelOne deeply). You’ll partner closely with MDR, Incident Response, Labs, and Detection Engineering to respond to emerging threats, convert research into actionable hunts, and communicate clearly with clients. What will you do? Threat Hunting Hunt Library Ownership Design, implement, and continuously improve a structured library of hypothesis-driven hunts and reusable rules aligned with the ATTCK framework. Execute proactive hunts across diverse telemetry (primarily EDR) to uncover malicious activity such as living-off-the-land techniques and stealthy persistence. Carry out all threat hunting activities in controlled FedRAMP environments. Translate findings into repeatable playbooks, automations, and platform-ready detections where applicable. Emerging Threat Response Triage emerging threats (e.g. zero-days) and assess potential exposure. Build focused hunts and detections mapped to relevant TTPs, with clear rationale and validation steps. Produce concise, actionable client advisories explaining scope and potential impact of the emerging threat, recommended mitigations, and the steps being taken by SentinelOne to protect our customers. Operational Partner Collaboration Partner with Detection Engineering, MDR, Labs, and CTI to evaluate and tune rules for fidelity and coverage. Curate and operationalize relevant IOCs/TTPs from CTI, Labs research, and OSINT into hunts and when appropriate convert those into platform detections. What experience or knowledge should you bring? 3+ years in security operations and/or adjacent disciplines (threat hunting, incident response, DFIR, malware analysis, SOC, or penetration testing). Strong familiarity with EDR telemetry (process, file, network, persistence)—SentinelOne experience is a plus. Proficiency with Python and Git/GitHub workflows (branches, PRs, code review); ability to turn hunt logic into robust, reusable code. Broad OS internals knowledge across Windows, Linux, and macOS.
