This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Head of AI based in the United Kingdom.
Join an ambitious engineering organization building next-generation AI systems that solve complex real-world cybersecurity challenges at scale. This is a rare opportunity for a hands-on technical leader to define AI strategy while remaining deeply involved in research, experimentation, and production development. You'll work alongside experienced engineering leaders to advance cutting-edge LLMs, autonomous agents, and evaluation frameworks that directly influence the company's competitive advantage. The role combines technical innovation, strategic decision-making, and product ownership in a fast-paced, remote-first environment where rapid iteration and measurable impact are valued. If you're passionate about agentic AI, production-grade machine learning, and solving problems that few organizations have tackled successfully, this position offers exceptional ownership and influence.
