📋 Description

• Get to Know Us • Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix, and verify exploitable attack vectors before criminals can exploit them. • Our flagship product, the NodeZero™ platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. • We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. • We’re looking for a Research Staff Member (Applied AI) to join our growing team of world-class engineers and security researchers in the San Francisco Bay Area. • As a Research Staff Member (RSM) at Horizon3 focused on applied AI, you’ll turn cutting-edge research into real-world impact. • Your mission: develop, prototype, and productionize AI systems that enhance our autonomous pentesting platform—powering reasoning, decision-making, and security insights at scale. • You’ll work on everything from agentic workflows and LLM reasoning to reinforcement learning and graph algorithms, bridging the gap between theory and battlefield-tested cyber capabilities. • This is where deep research meets operational relevance.

🎯 Requirements

• PhD or MS (with equivalent experience) in AI, Computer Science, or a related field • Strong publication or patent record in areas such as large language models, reinforcement learning, agentic AI, or graph-based learning • Proven experience applying modern AI research to real-world systems • Fluency with modern AI tooling (e.g., PyTorch, Hugging Face, LangChain, OpenAI APIs) • Strong programming skills in Python and familiarity with production-level ML/AI systems • Deep understanding of LLM-based architectures, fine-tuning techniques, and prompt engineering • Experience working with structured knowledge (e.g., graphs, knowledge bases, ontologies) • Familiarity with adversarial ML, secure AI development, or cybersecurity applications of AI is a plus
