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 Windows, Linux, and macOS researchers; people who are always looking to analyze and break things while looking for a complete understanding of how they work; people who live to beat the system and challenge it, and people who are in pursuit of outsmarting malware and overcoming it to protect our customers.

What will you do?

You’ll be part of an exceptional malware research team that will ensure we provide the best detection, protection, and visibility capabilities to our customers at any given time.

The team does it by performing in-depth analysis and research of threats and vulnerabilities while also being responsible for closing the loop through the development and deployment of signatures 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 mostly focused on research and development:


  • You’ll research and analyze (through reverse engineering and other methods) files, TTPs, exploits, and malwares to understand how they operate and behave. The research will mostly be based on binaries and files but may also be based on other types of data sources like events and behaviors.
  • Your research findings will be used for delivering new signatures and/or shared with other detection teams to improve our products’ detection capabilities.
  • As malware research experts, you’ll collaborate with many teams to help and support their work using your expertise, knowledge, or research.


  • You’ll be responsible for developing the signatures 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).
