We're looking for people that will drive team success and collaboration across SentinelOne. If you’re enthusiastic about innovative approaches to problem-solving, we would love to speak with you about joining our team!

What are we looking for?

We are looking for talented security researchers, people who look at the world differently, who explore, "hunt" and live to beat the system and challenge it. People who are in pursuit of outsmarting the malware and overcoming it.

What will you do?

You’ll be part of an exceptional research team that will ensure we provide the best detection, protection, and visibility capabilities to our customers at any given time. The team leads the vulnerabilities, exploits and anti-tampering research for all of our security products under all platforms.

The team does it by performing in-depth analysis and research of vulnerabilities and exploits, while also being responsible for closing the loop through the development and deployment of detection assets to millions of endpoints across the globe. You’ll be working closely with other detection teams to ensure our customers get the best security products they can.

Your time will be focus on research and detection & protection assets:

Research

• Assessing and evaluating our detection and protection coverage against in the wild vulnerabilities, exploits, and anti-tampering techniques (primarily for Windows and Linux).
• Closing the loop by conducting research to discover and implement innovative solutions for these security challenges.
• Initiate and propose new features and capabilities, leveraging personal experience and expertise in security research.
• Perform strategic long-term research projects that involve deep research of OS internals, new detection techniques, and novel threats. 
• Continually learn about emerging vulnerabilities, exploits, threats, techniques, and new technologies on a regular basis.
• As a security research expert, you’ll collaborate with many teams to help and support their work using your expertise, knowledge, or research.

Detection And Protection assets

• You’ll be responsible for developing the new detection content for all of our engines that will improve our detection, protection, and visibility, reaching all of our millions of endpoints across the globe. 
• You’ll be responsible for the quality and accuracy of the deliverables that you’ll create and be accountable for them.
• You’ll create, maintain, and improve existing infrastructure and tools that are being used by the team.

You will also be encouraged to write white papers, blogs, and articles (but only if you wish to).
