[Remote] AI Security Research Engineer II (Full Time) - (United States)
Auto ImportNote: The job is a remote job and is open to candidates in USA. Cisco is revolutionizing how data and infrastructure connect and protect organizations in the AI era. They are seeking an AI Security Research Engineer II to conduct and share applied security research that enhances the secure use of AI across the organization, combining security research with engineering to ensure AI systems are securely developed and integrated.
Responsibilities
- Executes straightforward, short-term AI security initiatives with guidance (e.g., one- to three-month deliverables such as a new guardrail, a GitHub Action security check, or an evaluation harness)
- Influences a single feature or product team, helping them reach a secure outcome faster with AI, not despite it
- Applies a working understanding of AI/ML security concepts and frameworks (OWASP LLM Top 10, OWASP Agentic Top 10, MITRE ATLAS, NIST AI RMF) and develops judgment on ethical and responsible-AI considerations
- Supports AI-specific threat models for AI-native features (RAG, tool use, agentic workflows, MCP (Model Context Protocol) integrations), including risks such as prompt injection (direct and indirect), jailbreaks, data poisoning, model extraction, excessive agency, and supply-chain risk
- Runs defined adversarial tests and evaluations using Cisco AI Defense (Cisco's AI security solution) alongside open-source tooling such as NVIDIA's Garak; documents findings, success rates, and remediation guidance
- Builds or contributes to security tooling and guardrails (input/output filtering, automated checks, and release gates), delivered in CI/CD pipelines and agentic workflows under direction
- Integrates AI security into existing Secure Development Lifecycle practices: threat modeling, SAST/DAST/SCA, dependency and supply-chain, secrets, and licensing
- Supports data protection requirements for AI systems, including data classification, minimization, residency, and sensitive data handling
- Supports human review, approval, and accountability controls for AI-assisted development and agentic workflows
- Contributes to AI security standards, patterns, and security requirements, treating reference architectures as living documents that absorb emerging threats and engineering feedback
- Develops and tests hypotheses about AI attack surfaces and control effectiveness; uses measurable evidence rather than manual assertions
- Shares findings and demos with the team and partner groups with guidance; interacts with peers to understand cross-functional security needs
- Contributes to reusable patterns, training material, office hours, and security champion enablement for engineering teams
- Contributes to literature reviews, threat research write-ups, and presentations shared within the company; participates in internal and external AI security talks and discussions
- Develops familiarity with the fast-moving AI/LLM platform, agent-framework, and attacker-technique landscape through hands-on experimentation
Skills
- Bachelor's + 2 years of related experience, or Master's + 0 years of related experience
- Foundation in security engineering (application/product security, secure SDLC, threat modeling) and/or AI/ML engineering, with demonstrated adversarial thinking
- Proficiency in Python
- Hands-on exposure to LLM security: prompt injection defense, guardrails, insecure output handling, RAG and agentic-system risks
- Familiarity with AI red-teaming/eval tooling, including Cisco AI Defense and an open-source framework such as NVIDIA's Garak
- Experience with CI/CD, MCP (Model Context Protocol), agent-to-agent integration patterns, and AI development tools (Cursor, Claude Code, Copilot)
- Knowledge of OWASP LLM/Agentic Top 10, MITRE ATLAS, NIST AI RMF, ISO/IEC 42001, or the EU AI Act
- A portfolio of applied work (security tooling contributions, CTF participation, or published threat research) is valued over certifications
Benefits
- Medical, dental and vision insurance
- A 401(k) plan with a Cisco matching contribution
- Paid parental leave
- Short and long-term disability coverage
- Basic life insurance
- Employees may be eligible to receive grants of Cisco restricted stock units, which vest following continued employment with Cisco for defined periods of time.

- Exempt employees participate in Cisco’s flexible vacation time off program, which has no defined limit on how much vacation time eligible employees may use (subject to availability and some business limitations)
- 80 hours of sick time off provided on hire date and each January 1st thereafter, and up to 80 hours of unused sick time carried forward from one calendar year to the next
- Additional paid time away may be requested to deal with critical or emergency issues for family members
- Optional 10 paid days per full calendar year to volunteer
- For non-sales roles, employees are also eligible to earn annual bonuses subject to Cisco’s policies.
