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.Job description\nBeyond research, the team designs and implements detection mechanisms and translates these defenses into shipping products across endpoint, cloud, and standalone form factors.\nAs 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.\nAbout the Role\nResearch attacks against conversational AI systems - exploring, probing, and breaking them to discover vulnerabilities before adversaries do.\nDesign and propose mitigations, protections, and detection strategies based on findings from adversarial research.\nBuild a multilayered detection core, combining different approaches toidentifymalicious prompts andattemptsto manipulate AI systems.\nProductize detection capabilities - packaging anddeploying themacross endpoint, cloud, and standalone environments.\nCollaborate with the broader threat detection department, product teams, and endpoint teams to integrate defenses into shipping security solutions.\nEvaluate and experiment with open-source and proprietary AI tooling to stay current with the rapidly evolving attack surface.\nShape the team's technical direction andmethodologyas a founding member, with the opportunity to grow into a Team Lead role over time.\nEssential Requirements\nStrong software engineering background - ability to build production systems, not just prototypes.\n\nProficiencyin Python for building detection and security tooling.\n\nUnderstanding ofhow large language models work and how they can be manipulated or attacked, including prompt injection, jailbreaking, and adversarial inputs.\n\nAbility to work independently in a newlyformingteam with minimal defined processes.\n\nDesirable Requirements\nExperience with machine learning and AI, including fine-tuning and deploying language models.\n\nC++ for performance-critical detection components.\n\nBackground in cybersecurity or threat research.\n\nTechnologies\nPython, C++,PyTorch, TensorFlow, Hugging Face, scikit-learn,vLLM,Ollama, ONNX, Docker, Kubernetes, AWS, Hadoop, Spark, Kafka, OpenClaw,OpenCode, Git, JIRA, Confluence\nCompensation\nBasic wagecomponent(brutto): from 2800 EUR/m.
