The Team To stay ahead of the curve, its critical to know where the curve is, and how to anticipate the changes were facing. For the fastest-growing cybersecurity company, the curve is the evolution of cyberattacks and the products and services that dedicatedly address them. Our engineering team is at the core of our products - connected directly to the mission of preventing cyberattacks. They are constantly innovating - challenging the way we, and the industry, think about cybersecurity. These engineers arent shy about building products to solve problems no one has pursued before. They define the industry, instead of waiting for directions. We need individuals who feel comfortable in ambiguity, excited by the prospect of challenge, and empowered by the unknown risks facing our everyday lives that are only enabled by a secure digital environment. Job Summary We are looking for a Linux Internals Software Engineer for our Tel Aviv R&D center. You will be part of a team that designs and develops the Linux internals components of our revolutionary endpoint security product for the Linux platform. More information about Cortex XDR product can be found here.

We are looking for an experienced individual to join a team that is responsible for developing our cutting-edge collection, prevention and protection technologies using both documented and undocumented proprietary kernel mode techniques.
The tam develops the core kernel technologies for a wide variety of products, from EDR to next-gen AV, including work that encompasses many aspects of kernel development, from infrastructure through filter drivers to function hooking, to name a few.
In this position you will:
Write kernel software that can reach the depths of the operating system.
Implement novel collection and protection techniques.
Write robust driver infrastructure.
Optimize for extreme performance constraints.
Research uncharted territories of the Windows kernel, drivers, APIs, and internal mechanisms.

Were looking for a senior engineer with strong systems-level thinking and a good understanding of Linux. You should be comfortable working close to the kernel, ideally with experience in eBPF, or with a strong desire to dive into it. Proficiency in C/C++/ Go is essential, and familiarity with networking protocols, TLS internals, or distributed tracing is a strong advantage.

Youll join a high-impact team tackling ambitious technical challenges-like decoding traffic across multiple protocols, and ensuring high-fidelity metrics in complex, real-world environments. Youll be expected to lead design and implementation efforts, contribute to roadmap planning, and collaborate across teams to ensure our solution remains robust, scalable, and frictionless for our users.

This role is a great fit for engineers who thrive on low-level, performance-sensitive problems, and want to shape the future of observability through cutting-edge kernel technology.

We are looking for a unique talent to bridge the gap between low-level system observability and high-level AI reasoning. You will sit at the intersection of our deep tech initiatives: actively developing our eBPF agent (Cimon) while simultaneously leading the charge on our AI innovation security research.
In this role, you will be the architect of our "security brain." You will write the low-level code that observes what is happening (eBPF/Golang) and build the AI models that understand, diagnose, and prevent issues (LLMs/Python).

We are looking for a passionate and skilled Backend Developer to join our dynamic team! If you're excited about working on large-scale cloud-based security systems and enjoy solving complex challenges, this is the perfect opportunity for you.
As part of our backend team, you will develop and enhance server-side components for cutting-edge security services. You will work with big data, AI-driven analysis, and a microservices architecture that serves millions of users worldwide.
What You'll Do:
Design and develop new features to meet customer needs
Optimize and scale existing services to ensure high performance
Collaborate with other teams (Mobile, Agents, etc.) for seamless integration
