You will become part of the newly established AI Threat Research and AI Conversation Security team within the Technology Division in Bratislava. As a founding member, you have a unique opportunity to shape the team's direction and methodology from the ground up. The team researches attacks against conversational AI systems — probing and breaking them to understand how adversaries exploit large language models.
Beyond research, the team designs and implements detection mechanisms and translates these defenses into shipping products across endpoint, cloud, and standalone form factors.
As a Conversational AI Security Engineer, you bridge adversarial research and production engineering — building detection mechanisms to defend conversational AI systems and shipping those defenses as products. Your work spans the full lifecycle, from breaking models to running detection in production.
