We are looking for a Sr Principal Linux Security Researcher for our Tel Aviv R&D center, to work on cortex-xdr for linux, which provides runtime protection to servers and cloud workloads.
You will be part of a team that is in charge of researching, developing and improving Anti-Exploit capabilities, Anti-malware capabilities. The position includes researching OS internals, exploits, malware, delving into cloud security, and finding ways to mitigate new attack vectors.
Your Impact
Research, develop, and improve anti-exploitation mitigations and anti-malware modules - ranging from low-level mitigations up to tackling application-level security vulnerabilities
Work on the design, evaluation, and implementation of new security technologies
Research Linux OS internals, kernel, application codebases, vulnerabilities and exploits (Mostly internal usage but also PR)
Analyze customer issues to help with detecting and preventing malicious activities in our customers networks.

The eBPF APM team is building a zero-instrumentation observability solution that automatically discovers services on every host, supports both plaintext and TLS-encrypted traffic, classifies Layer 7 protocols, decodes service-level traffic, and reports RED (requests, errors, duration) metrics. Leveraging deep expertise in eBPF, the team operates across a wide range of Linux kernel versions, distributions, and complex customer environments. In addition to low-level networking, the team solves challenges related to protocol versioning, TLS detection across diverse languages and runtimes, and resilient performance in production systems​.

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 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 challengeslike 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 place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.

What Youll Do:
Design and build core components of our zero-instrumentation APM product using eBPF and Go
Develop systems to auto-discover services, classify L7 protocols, and extract RED metrics from both plaintext and TLS traffic
Solve complex challenges around protocol parsing, encryption handling, and performance at the kernel level
Ensure broad compatibility across Linux kernel versions, distributions, and diverse customer environments
Collaborate across teams to drive technical direction, improve reliability, and scale the system for production use
