[Hiring] Senior Research Staff, Adversarial Intelligence @Horizon3

Role Description

We're looking for an experienced Research Staff Member to join Horizon3 AI Research and lead research problems at the intersection of super intelligence, systems security, and agentic systems for security. You'll identify and investigate technical problems that arise from real security environments and turn promising research directions into methods, prototypes, experiments, and systems that can influence Horizon3's technology.

This is not a purely academic research role and it is not a conventional software engineering role. We are looking for someone who can move between research questions and working systems:

• Define the problem
• Understand the relevant literature
• Develop a technical approach
• Build or guide implementation
• Design rigorous experiments
• Determine what the results actually tell us

You do not need to be an expert in every area of AI and systems security. You should bring substantial technical depth in at least one of these areas, strong computer science foundations, and the ability to develop expertise quickly in unfamiliar domains.

This role may be hired at the P3 (Career) or P4 (Senior) level based on experience, technical depth, independence, and demonstrated ability to lead complex research efforts.

Qualifications

• Strong foundations in computer science, with the ability to reason deeply about algorithms, systems, software, and data.
• Significant technical depth in systems security, super intelligence / machine learning, or a closely related area.
• Demonstrated ability to independently identify, structure, and solve complex technical problems.
• Experience conducting research or advanced technical investigation.
• Strong programming and software engineering skills.
• Ability to design rigorous experiments and evaluation methodologies.
• Ability to critically evaluate technical literature.
• Interest in both research and engineering.
• Strong technical judgment.
• Ability to provide constructive technical guidance and mentorship.
• Ability to work independently while collaborating closely.
• Strong written and verbal communication skills.
• A degree in Computer Science or a related field, or equivalent technical experience.

Requirements

• Deep experience in systems security, offensive security, defensive security, penetration testing, vulnerability research, operating systems, networks, distributed systems, cloud security, identity systems, or related fields.
• Deep experience in machine learning, deep learning, large language models, AI agents, reinforcement learning, planning, search, graph reasoning, program analysis, or related AI and systems methods.
• Experience leading or contributing to research projects from initial problem formulation through implementation, evaluation, and communication of results.
• Experience defining new research directions.
• Experience building research systems that operate on realistic environments.
• Experience designing experimental infrastructure, evaluation frameworks, benchmarks, or test environments.
• Familiarity with cybersecurity concepts such as attack paths, Active Directory, cloud environments, identity systems, security controls, adversarial techniques, and autonomous security systems.
• Experience mentoring junior researchers, engineers, students, or interns.
• Strong research publications, patents, conference presentations, open-source contributions, or other evidence of high-quality technical work.
• Experience transferring research ideas into production systems.

Benefits

• Inclusive Team: We value diversity and promote an inclusive culture where everyone can thrive.
• Growth Opportunities: Be part of a dynamic and growing team with numerous career development opportunities.
• Innovative Culture: Work in a collaborative environment that encourages creativity and out-of-the-box thinking.
• Hybrid & Remote Work: We embrace a mix of remote and hybrid work models.
• Competitive Compensation: We offer competitive salary, equity, and benefits including health, vision & dental insurance, flexible vacation policy, and generous parental leave.
