Staff+ Researcher, Cybersecurity Products

Details

Anthropic is seeking a Capabilities Researcher to join the team building Claude Security. The role focuses on identifying security capabilities in frontier models that are ready to build on, measuring their performance, and making them useful to customers who are not security experts.

The researcher will investigate which capabilities are reliable enough to depend on, how they perform in realistic conditions, how they behave when adversaries are involved, and where their limits are. The role combines rapid prototyping, rigorous evaluation, and product development in collaboration with engineers and researchers.

Responsibilities

• Prototype rapidly to define the AI frontier for cybersecurity work.
• Design evaluations that measure model performance on work security teams actually do.
• Build the datasets, harnesses, and scoring systems required for evaluations.
• Engage with the cybersecurity community to help define where AI can make the greatest impact.
• Work with engineers and researchers to operationalize promising capabilities into products customers can rely on.
• Track how model capabilities for security are changing and determine what that means for future product development.
• Share findings that inform product direction and partner with product leadership on priorities.
• Design scaffolding, tooling, and defaults that help non-experts use strong model capabilities effectively.

Requirements

• Deep expertise in one or more security domains, such as vulnerability research, exploit development, reverse engineering, malware analysis, incident response, or offensive security.
• Experience building AI-powered tools or capabilities for security work.
• Ability to move quickly from an idea to a working prototype and abandon approaches that do not hold up.
• Comfort designing rigorous evaluations and interpreting results honestly.
• Ability to write and communicate clearly about technical findings.
• At least 7 years of experience in security research, security engineering, or a closely related field.
• Bachelor's degree or an equivalent combination of education, training, and experience.
• Education or professional experience in a field relevant to the role.

Preferred Qualifications

• Published research, CTF results, CVEs, or open-source security tooling.
• Experience with model evaluation, benchmarking, or red teaming.
• Experience building agentic applications.
• Familiarity with the safety considerations of AI in security contexts.

Compensation

• Annual salary: $405,000–$485,000 USD.

Benefits

• Hybrid policy requiring staff to work from an Anthropic office at least 25% of the time; some roles may require more office time.
• Competitive compensation and benefits.
• Optional equity donation matching.
• Generous vacation and parental leave.
• Flexible working hours.
• Office space for collaboration.
• Visa sponsorship is available, although eligibility depends on the role and candidate.
