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.
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.
As a Senior Threat Researcher, you will be tasked with taking apart emerging and known cyber threats - leading in-depth investigations into threat actors, their capabilities, tools and operations, spanning across Endpoint and Cloud domains. This role combines hands-on technical analysis with strategic intelligence production, enabling our ThreatOps teams to protect our customers from adversaries across the ever evolving threat landscape.
What Will You Do?
Conduct deep-dive technical analysis of malware samples, attacker infrastructure and protocols.
Track adversary progression, develop and maintain technical reports on threat actor profiles, malware families, and campaign timelines - curate and expand our internal Knowledge Base and IOCs collections.
Collaborate with threat intelligence, detection engineering, threat hunting and incident response teams in investigating intrusions and to translate research into actionable detections and defenses.
Work with our lab teams to improve our internal infrastructure and tooling.
Present findings to technical teams, leadership, and occasionally external partners or customers.
What Skills and Knowledge Will You Bring?
Ideal candidates will have:
5+ years of experience in malware analysis, threat intelligence, threat hunting or incident response.
Deep understanding of the cybersecurity landscape, attack vectors and TTPs, especially on Windows.
Experience in reverse engineering (x86/x64, ARM\ARM64) and malware analysis (statically and dynamically).
Proficiency in C/C++ and scripting languages (Python, Powershell).
Experience with creating signatures (YARA, Snort, Sigma) to identify and track malware families.
Technical writing & content development skills.
Proven track record of publication or speaking at security conferences - advantage.
Experience leveraging agentic AI workflows for malware analysis and detection engineering tasks (reverse engineering, code auditing, signature writing) - advantage.
Knowledge about internal working of EDR products - advantage.
Why SentinelOne?
AI 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.
