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).
Requirements:
4+ years of experience as a software developer in the area of low level programming.
4+ years' experience in C and C++.
