Senior Windows Malware Researcher / Detection Engineer

As a Senior Windows Malware Researcher / Detection Engineer  you will be tasked with helping shaping the future of endpoint security through a unified, converged platform that automatically prevents, detects, and responds to threats in real time. You will design and develop advanced Windows detections by combining deep system process inspection, behavioral analysis, and innovative machine learning techniques to identify and stop sophisticated attacks before they cause harm.

You will join a growing team of passionate security experts and technical leaders who think differently, challenge assumptions, and constantly explore new ways to outsmart adversaries. In this role, you will hunt for emerging threats, solve complex security problems, and deliver high-impact detection capabilities with speed and precision.

What Will You Do?

Primary responsibilities include:

• 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.
• You will also be encouraged to write white papers, blogs, and articles (but only if you wish to).
•  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 Skills and Knowledge Will You Bring?

Ideal candidates will have:

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

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.
