Job Summary
Your Career
Are you a highly technical individual with a passion for performance engineering Join our innovative Cortex XDR Agent Performance team as a Senior Performance Engineer!
Our team is responsible for all performance aspects of the Cortex XDR Agent developing maintaining and executing various performance tests to ensure our products are stable minimize resource impact and meet our SLA. As a Senior Performance Engineer you will diagnose performance-related issues in a highly challenging product that is widely deployed in millions of customer environments across Windows Linux and macOS. Additionally you will collaborate closely with different engineering teams to enhance performance test coverage and modernize our approach by heavily automating workflows and integrating smart analytical tools.
Your Impact
Design build and maintain sophisticated Python-based automation frameworks that orchestrate performance tests across diverse endpoint environments (Windows Linux macOS and Kubernetes nodes). Your frameworks will need to simulate complex user behaviors and system stress scenarios.
Move beyond manual analysis of disparate logs. Proactively leverage AI-driven analytics and GenAI tools to summarize complex cross-OS performance data detect anomalies in resource usage trends and accelerate root cause analysis of hard-to-reproduce issues.
- Go beyond high-level metrics. Take a hands-on approach to diagnosing complex agent performance issues (e.g. memory leaks high CPU context switching I/O blocking or boot time impact). You will use native OS profiling tools to pinpoint bottlenecks at the process or kernel level.
Qualifications :
Your Experience
5 years of experience in performance engineering with a strong emphasis on endpoint software system-level testing or embedded systems rather than just web-application load testing.
Highly proficient in Python capable of moving beyond simple scripting to architect maintainable production-grade software. You have a strong portfolio of building automation systems that interact with OS-level APIs and manage external processes.
Experience in designing and maintaining CI pipelines (e.g. Jenkins) to automate testing and deployment of complex system-level tools.
Strong understanding of operating system concepts (processes threads memory management file systems networking stack) across at least two major platforms (Windows / Mac / Linux). Kubernetes is a must.
A proven track record of adopting new technologies to work smarter. Specifically experience leveraging AI/LLM tools within your engineering workflow - for example using AI to analyze massive system logs generate test cases based on feature specs or optimize Python code.
System Profiling Tooling: Hands-on experience with OS-specific performance and debugging tools
Deep experience with monitoring stacks (Prometheus Grafana etc.)
Excellent communication and interpersonal skills in both Hebrew and English with the ability to explain complex technical data to varied audiences.
Ability to work independently in a fast-paced environment and as a collaborative part of a team.
