Full-timeTel Aviv-Yafo, Israel

About the Job

Requirements

  • At least 5 years of hands-on offensive security work, including at least 3 years focused on endpoint defense evasion.
  • Expert-level understanding of operating-system internals and the mechanisms security products rely on for visibility.
  • Practical knowledge of how commercial endpoint detection and response products work, what they observe, and where their coverage ends.
  • Strong C/C++ and Python skills, with familiarity with assembly and reverse-engineering tools such as IDA, Ghidra, and WinDbg.

Responsibilities

  • Own endpoint evasion research and development by tracking how leading endpoint detection and response, extended detection and response, and antivirus products detect attacker behavior and keeping the attack library ahead of them.
  • Research, prototype, and productize evasion techniques observed from real threat actors across Windows, Linux, and macOS as safe, reversible, and measurable simulations.
  • Build and maintain stealthy, stable attack components with a strong emphasis on operational safety in customer environments.
  • Partner with other attack developers and platform engineering teams to integrate work into the SafeBreach simulator and post-breach propagation engine.
  • Use artificial intelligence coding agents to accelerate research, tooling, and content delivery.

Desired Qualifications

  • Background in red teaming, adversary emulation, or advanced persistent threat simulation against mature, well-defended environments.
  • Experience on the defensive side, such as building detections, working at an endpoint detection and response vendor, or tuning endpoint products.
  • Experience with MITRE ATT&CK and implementing or simulating ATT&CK techniques.
  • Understanding of modern threat actor tactics, techniques, and procedures and practical application in research environments.

About the Company

SafeBreach

Tests defenses with real-world attack simulations

SafeBreach tests client defenses by safely and continuously running real-world attack simulations to quantify a security posture. Its platform integrates with existing security controls like SIEM and SOAR to collect data and provide measurable performance metrics, showing how effective defenses are and where gaps exist. Unlike generic security tests, SafeBreach delivers ongoing, data-driven insight into attack surface and risk. The company works with a wide range of clients—from law firms and healthcare organizations to technology companies—to identify gaps, speed remediation, and reduce overall risk. The goal is to help clients validate and strengthen their security controls, translating findings into actionable improvements and a stronger defensive posture.
