Research Intern, Adversarial Intelligence at horizon3ai · LumiJobs

Responsibilities

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 exploit them. Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs.
We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.
We're looking for Research Interns to join Horizon3 AI Research and work on technical problems at the intersection of super intelligence, systems security, and agentic systems for security.
You'll work on a concrete research problem with researchers and engineers at Horizon3. Depending on the project, this may include AI agents for security, autonomous pentesting, attack-path reasoning, cyber deception, AI safety and security, security evaluation of AI systems, or new methods for reasoning over security data and environments.
This is a hands-on research internship. You will not only study a problem or read the relevant literature; you will also build, experiment, analyze results, and communicate what you learn. Projects may involve research prototypes, experimental infrastructure, AI models or agents, security test environments, attack graphs, system telemetry, or other technical artifacts.
We do not expect every intern to arrive with expertise in both AI and systems security. You should have strong computer science foundations, meaningful experience in at least one relevant technical area, and genuine interest in developing expertise across AI and security.
Interns will receive mentorship and technical guidance throughout the summer, but we also expect curiosity, initiative, and a willingness to investigate difficult technical questions independently.
Work on a defined research project at the intersection of AI, cybersecurity, and computer systems.
Understand the research problem, relevant technical background, and existing approaches.
Read and critically evaluate academic papers and technical material related to the project.
Develop and implement research ideas, algorithms, prototypes, or experimental systems.
Design and run experiments to evaluate research hypotheses and technical approaches.
