Duties and Responsibilities:

• Perform security architecture reviews and threat modeling for AI-enabled applications.
• Conduct hands‑on security testing of LLM, RAG, and agentic AI solutions.
• Identify vulnerabilities including prompt injection, sensitive‑data exposure, insecure retrieval, excessive permissions, unsafe tool use, and authorization weaknesses.
• Assess security risks associated with AI agents, APIs, model integrations, vector databases, and third‑party AI services.
• Partner with developers and AI engineering teams to design and implement practical security controls.
• Develop reusable security patterns and guardrails for common AI architectures.
• Build or automate security tests and tools used to evaluate AI applications.
• Help protect PHI, PII, credentials, and other sensitive information used by AI systems.
• Evaluate emerging AI security threats and translate relevant findings into engineering guidance.
• Support the organization’s broader application security and secure AI development practices.
• Help ensure AI systems handling sensitive healthcare and enterprise information are designed with appropriate security and privacy controls.
• Assess how PHI, PII, and other sensitive information moves through prompts, models, APIs, retrieval systems, embeddings, vector stores, logs, agents, and downstream systems.
• Partner with privacy, compliance, legal, risk, and AI governance teams to translate requirements into practical technical controls.
• Support secure and responsible AI adoption consistent with organizational policies and applicable healthcare and regulatory requirements.
• Additional duties as required.

Minimum Qualifications:

• Technical Degree in Computer Science or Cyber Security and/or equivalent work experience
• Prior work Cyber Security work experience
• Experience in security engineering, vulnerability assessment, threat hunting, and incident response
• High School diploma or GED from an accredited institution

Preferred Qualifications:

• 5+ years of experience in application security, product security, security engineering, cloud security, offensive security, or a related technical security discipline.
• Strong understanding of application and API security, authentication, authorization, identity, data protection, and secure software development.
• Hands‑on experience with security architecture reviews, threat modeling, vulnerability assessment, penetration testing, or security testing.
• Working knowledge of modern AI application architectures, including LLMs, model APIs, RAG, vector databases, and AI agents.
• Understanding of AI security risks such as prompt injection, data leakage, insecure output handling, excessive agency, and unsafe tool or API access.
• Programming or scripting experience, preferably Python.
• Experience working with cloud‑based applications and services.
• Ability to communicate technical security risks and remediation recommendations effectively to engineering teams.
• Experience securing production generative AI or LLM applications.
• Experience with AI/LLM security testing or red teaming.
• Familiarity with agentic AI security, including tool permissions and least‑privilege access.
• Familiarity with Model Context Protocol (MCP) security considerations.
• Experience with Azure OpenAI, AWS Bedrock, Google Vertex AI, or comparable AI platforms.
• Familiarity with OWASP guidance for LLM/GenAI applications, MITRE ATLAS, or NIST AI security guidance.
• Experience working with PHI, PII, or other sensitive data in a regulated environment.
• Experience integrating security testing into CI/CD or DevSecOps workflows.
• Experience with software supply‑chain security and SBOM practices, including assessing third‑party libraries, dependencies, models, prompts, and other AI application components for security risk.
• Experience designing secure tool and API consumption patterns for agentic AI, including authentication, authorization, least privilege, trust boundaries, credential management, and control of agent actions.
• Experience reviewing or implementing Infrastructure as Code (IaC) and applying security controls to cloud and AI infrastructure; experience with Terraform, Bicep, CloudFormation, or comparable frameworks preferred.
