Description
As an AI Security Engineer on Tenable's Information Security team, you will help shape and mature our approach to securing AI both within Tenable's products and across the enterprise.
Your Role: You will apply hands-on AI engineering experience alongside product security and application security skills to design security controls for AI systems, lead assessments, and help engineering teams ship AI features securely.
Responsibilities:
- Design, implement, and maintain end-to-end security controls across the AI/ML lifecycle.
- Assist in the implementation of robust security guardrails, controls, and boundary mechanisms for Large Language Models (LLMs), Small Language Models (SLMs), and open-source models.
- Continuously monitor the AI landscape for novel vulnerabilities and attack techniques, applying deep engineering experience to proactively defend enterprise AI deployments.
- Assist in developing security reference architectures for AI deployment patterns, including MCP servers and agentic AI workflows and harnesses.
- Deploy controls to ensure model integrity, governance, and proper access control across models and feature stores.
- Build AI-driven tooling to strengthen cybersecurity posture across identity, incident management, vulnerability management, third-party risk, and emerging AI threat vectors.
- Perform AI safety, security assessments, threat modeling for AI/ML systems, identifying risks such as data poisoning, model evasion, model extraction, adversarial inputs, and integrity attacks.
- Collaborate with software engineers, and product teams to integrate security best practices into AI development, training, validation, and deployment processes.
- Create security guidance, documentation, and training for internal engineering and development teams; develop metrics that drive desired security behaviours and outcomes.
- Assist in researching emerging trends in AI security and contribute to innovative solutions that support Tenable's AI initiatives.
Requirements:
- 2 or more years of professional experience in information security or application security, with at least a demonstrated interest on securing AI/ML systems.
- Bachelor’s Degree in Computer Science, Cybersecurity, Data Science, or a related field preferred.
- Awareness of AI-specific security threats, including adversarial ML, data poisoning, prompt injection, model inversion, model evasion, and inference attacks.
- Knowledge of data security principles, including encryption, masking, and tokenization.
- Knowledge of SSDLC, DevSecOps, and security testing practices, including SAST, DAST, SCA, and threat modeling.
- Knowledge of application security architecture best practices and patterns, including modern web applications, Docker, and microservices.
- Ability to work cross-functionally across engineering, product, and business teams.
- Strong written and verbal communication skills; able to clearly translate complex AI security risks for both technical and non-technical audiences.
- Strong problem-solving skills, attention to detail, and ability to lead projects with end-to-end ownership.
- Self-motivated and effective working independently and across distributed teams.
Preferred Qualifications:
- Hands-on experience with AI red teaming, adversarial prompt testing, or LLM security assessments.
- Basic coding experience in Python and/or Go.
- Experience with frameworks & libraries such as PyTorch, Hugging Face Transformers, TensorFlow or similar.
- Strong understanding of the ML/AI lifecycle and the security risks associated with each stage.
- Experience with application security assessment tools (Burp Suite, ZAP, Tenable WAS, etc.).
- Knowledge of cloud security platforms: AWS, Azure, or GCP including AI/ML-related services.
- Security certifications: CISSP, CSSLP, SANS GIAC, CEH, or AI-focused security certifications are a plus, but not necessary.
