Job description

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.

About Us

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 Intelligence Researcher, you will be tasked with leading deep-dive investigations into both emerging and known threats, while maintaining a vigilant watch over malware developments to ensure defenses remain a step ahead of evolving attack methods. You will synthesize complex data into actionable intelligence and provide senior management with the clear briefings necessary to understand and mitigate potential risks. You will also develop refined hunting strategies to adapt to and anticipate shifts in threat actor tactics and techniques, and track adversary infrastructure to effectively counteract shifts in threat actor tradecraft through detail-oriented investigation.

What Will You Do?

Primary responsibilities include:

Synthesize complex data, from internal hunt findings to intelligence gathered from dark web forums, leak sites, and research repositories, into actionable threat briefings and risk assessments for security leadership and senior stakeholders.
Lead in-depth, hypothesis-driven threat hunts across internal networks, cloud environments, and endpoints to uncover sophisticated intrusions that evade traditional security controls.
Map threat actor footprints internally by pivoting through EDR telemetry.
Analyze adversary tactics, techniques, and procedures (TTPs) within the environment, identifying shifts in execution, persistence, and lateral movement.
Trace adversary infrastructure externally by pivoting through domain registrations, SSL certificates, and passive DNS.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

A background in threat intelligence or threat hunting.
Knowledge of the cyber threat landscape, including threat actors and their tactics, techniques, and procedures (TTPs).
Strong analytical skills, with the ability to identify patterns and trends in large datasets.
Knowledge of how our products operate internally and how to maximize their telemetry.
Strong knowledge of YARA to track new malware families, along with knowledge of validation best practices.
An understanding of software vulnerabilities and the ability to implement internal hunting strategies to track their exploitation across the estate.
Knowledge of MITRE ATT&CK, CISA KEV, EPSS, AMITT, and MISP Galaxy.
Knowledge of malware analysis tools and techniques, including static and dynamic analysis, sandboxing, and debugging.
Technical writing and content development skills.
A solid technical understanding of how EDR works is preferred.
Relevant certifications, such as Certified Malware Analyst (CMA), Certified Reverse Engineering Analyst (CREA), or GIAC Certified Malware Reverse Engineer (GREM), are preferred.

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. If you want to build where innovation and impact move together, this is that place.
