As threat actors become more organized and AI reshapes the security landscape, we need a senior researcher who can operate at the intersection of applied AI, threat intelligence, and cyber operations-someone who can both advance what we know and change how we work. This is a senior individual contributor role for a researcher who lives at the frontier of AI and cybersecurity. Your primary mission is to research how threat actors are adopting, weaponizing, and exploiting AI
- from LLM-powered social engineering and automated vulnerability discovery to real-world attacks against agentic AI implementations. You'll help instrument telemetry to detect adversarial use of AI in the wild, assess emerging risks as AI capabilities evolve, and produce research that keeps Sophos and the broader security community ahead of the curve. As a domain expert in AI threats, you'll also be expected to help drive operational efficiencies across the Insights team, bringing the tools and techniques you research into our own workflows. You'll report to the Sr. Manager, Threat Research and work alongside CTU researchers, SophosLabs malware analysts, MDR threat hunters, incident responders, engineering teams, and data scientists.
