Desirable

• 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
• Conduct in-depth research into attacker techniques across Windows, Linux, identity systems, cloud environments, and external attack surfaces
• Design and develop advanced attack simulation techniques that challenge modern security controls and defensive architectures
• Translate research findings into scalable, production-ready capabilities within Pentera’s automated validation platform
• Architect and implement decision-making logic that enables dynamic attack paths and adaptive behavior during automated operations
• Develop high-quality code that powers complex attack simulations, using appropriate languages and technologies for each use case
• Collaborate closely with R&D, engineering, and product teams to integrate new research into the platform
• Mentor team members and contribute to a culture of technical excellence, curiosity, and continuous learning
