We are seeking a highly skilled Software Engineer with a background in low-level programming and a deep understanding of Windows internals to join one of our Platform group. Platform group is in charge of some of our most complex low-level areas, such as Windows agents Anti-Tampering (self-protection from a malware attempting to harm the agent), network sensors, and other kernel-side features involving both research and development.
By joining this team 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.
What will you do?
As a new member of our distributed development team, 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 and the Endpoint Protection as well as Endpoint Detection & Response eco-system.
Our team designs and executes significant new features, as well as rewrites and reimplements 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. 5 of Fortune 10 and hundreds of Global 2000)
