People who can address tough security problems and deliver it fastly.

What will you do?

• You will be responsible for detecting the newest malware and exploits based on SentinelOne’s Endpoint Protection platform. Your role won’t end with a hypothesis or a document – you’ll have an end to end responsibility for behaviour-based detection capabilities, starting from reversing the samples, designing new methods to detect or prevent those, and implementing it in the product in the end (SW development in C++23 and scripting in Lua).
• You will be developing and using internal research tools, PoCs and discovering new ways to detect/prevent exploitation attacks (EoP, drive-by attacks and more).
• At the end of the day, your deliveries will enhance the security of dozens of millions of Windows endpoints which are protected by our platform.

Why us? – Because you will meet extraordinary challenges facing the newest attacks and tech obstacles and overcoming them. You will work with the very BEST in the industry in a flexible and independent environment. You will influence the design of a disruptive product that will shape the security industry of tomorrow.

What experience or knowledge should you bring?

• Proven experience with reverse engineering of x86/x64/ARM binaries
• Several years of experience in malware analysis (statically and dynamically)
• Several years of experience with C++
• Excellent understanding of the Windows Internals – understanding how core system components (Process and Threads, Virtual Memory and more) work behind the scenes
• Experienced with analysis tools, such as: IDA, WinDBG, SysInternals etc.
• An advantage would be – kernel development experience, Python experience, and/or understanding of existing AVs internals
