About Pentera
Pentera is the global leader in Automated Security Validation, helping organizations worldwide safely emulate real-world attacker behavior and uncover their true security gaps across on-prem, cloud, and hybrid environments. With more than 1,200 customers in over 50 countries and a rapidly growing global team, Pentera is shaping how modern enterprises continuously validate their security posture.
About the Role
We are looking for a Cyber Researcher to join our R&D team and play a key role in shaping how automated security validation evolves.
In this role, you will conduct deep, hands-on technical research into attacker techniques and system behaviors across operating systems, identity systems, cloud platforms, and enterprise environments. Your work will be translated into production-grade, automated attack emulations that dynamically adapt and make decisions, closely mirroring how skilled attackers operate in the real world.
This is a highly technical role that combines research, development, and applied AI, with direct impact on a real-world security product.
