About Us

At Sentinel One, we’re redefining cybersecurity by pushing the limits of what’s possible—leveraging AI-powered, data-driven innovation to stay ahead of tomorrow’s threats.

From building industry-leading products to cultivating an exceptional company culture, our core values guide everything we do. We’re looking for passionate individuals who thrive in collaborative environments and are eager to drive impact. If you’re excited about solving complex challenges in bold, innovative ways, we’d love to connect with you.

What are we looking for?

We are seeking a highly skilled and experienced Software Engineer with a strong background in low-level C++ programming and a deep understanding of Windows OS, to help us in developing our Endpoint Protection product, the core part of our business, and to join one of our Platform group teams. (We're currently growing multiple teams and are open to new colleagues with a wide variety of backgrounds within Windows development!).

The Platform group teams are in charge of some of our most complex low-level areas, such as:

• Windows agent’s Anti-Tampering (self-protection from malware attempting to harm the agent), network sensors, device control, and other kernel-side features involving both research and development,

• usermode security & agent infrastructures - e.g. installers, logging, services such as communication layer & interfaces for our Windows agent, for improving the quality, performance & stability of the agent and making the user experience smoother.

By joining our group, you will collaborate with talented engineers who are leading a feature through the whole development lifecycle. Your work will have an impact on millions of endpoints in one of the mainstream areas of the EPP/EDR agent of Sentinel One - a product recognized 5x-in-a-row as Gartner MQ Leader, scoring highly in many MITRE Att&ck assessments, valued by users in Gartner Peer Insights and more.

What will you do?

• As a new member of one of our distributed development teams, you will work in both user-mode & kernel-mode, and deal with a large variety of fields.

• You will have the chance to design, develop primarily in modern C++ (23), test and debug the most complicated real-world problems (often unseen before). In order to successfully deal with this challenge, you will continuously enrich your knowledge and experience with Windows OS internals & Kernel, Endpoint Protection, and Endpoint Detection & Response eco-system.

• Our teams design and execute significant new features, as well as rewrite and reimplement the existing ones from scratch. You will also deal with extraordinary performance & optimization challenges, given the scale of our cybersecurity SW (handling hundreds of billions of events every day).

• Your work will influence the security of tens of millions of Windows devices, that we protect at enterprise & government customers across the globe (incl. 4 of Fortune 10 and hundreds of Global 2000).

• You’ll also be encouraged to share knowledge within both Platform teams and the broader Windows group.

What skills & knowledge should you bring?

• Multiple years of experience as a software engineer in the area of lowlevel programming using modern C++ (or using C and a willingness to learn modern C++)

• Hands-on experience and in-depth understanding of Windows OS design & internals, Windows low-level development, with debugging of Windows applications and familiarity with related standard debugging and profiling tools

• Previous experience working on a production-grade product with a wide-scale deployment

• Great communication skills and the ability to work both independently and with peers from different time zones, problem-solving and out-of-the-box thinking

• Attention to detail and high coding standards

• An advantage: experience with Windows Kernel and Windows Drivers development, experience in security-oriented development, with reversing or malware analysis

Why us?

Because you will work on real-world problems with risks of millions of dollars (protecting against Ransomware and other threats) and make an impact by preventing our customers from appearing in global news after being attacked. You will be joining a technologically cutting-edge project and will be able to influence the architecture, design, and building of our core platform. You will meet extraordinary challenges and work with the very BEST in the industry.
