Description

• Design, implementation, and maintenance of security controls across the full AI/ML lifecycle, including training data validation, model registry policies, deployment guardrails, and production monitoring for anomalous model behavior. • Develop and maintain comprehensive threat models for AI/ML systems, covering prompt injection, data leakage, model evasion and extraction, data poisoning, and agent hijacking scenarios. • Lead red teaming and adversarial testing of LLMs and agentic workflows — including jailbreak attempts, prompt injection, output manipulation, and business logic abuse — and drive remediation with engineering teams. • Partner with ML engineers to embed security into model development pipelines, including secure training, evaluation, and deployment processes, as well as secure use of RAG architecture, tooling integrations, and multi-agent workflows. • Implement and define policies for safe prompt and response handling, including PII and sensitive content detection, output filtering, and usage logging to support investigations and compliance requirements. • Work with security engineering to integrate AI telemetry into SIEM, EDR, and SOC workflows; define and maintain runbooks for AI-related security incidents and forensic investigations. • Lead the creation, modification, and maintenance of AI security documentation, including threat model reports, security specification documents, SOPs, data flow diagrams, and network topology documentation. • Stay current on AI-specific attack techniques, emerging tooling, and relevant frameworks (NIST AI RMF, OWASP LLM Top 10, MITRE ATLAS, secure AI development guidelines) and translate findings into internal standards and controls. • Consult and collaborate with cross-functional SMEs across ML, Product, Platform Engineering, Legal, and Compliance to influence security design decisions and ensure operability and technical feasibility. • Provide technical mentoring and oversight to less experienced security engineers responding to and investigating AI-related security issues. • Create, edit, and adhere to Standard Operating Procedures (SOPs), security playbooks, and standardized documentation templates. • Perform ad-hoc and cross-functional projects assigned to support business needs and provide developmental opportunities.

🎯 Exigences

• Bachelor's degree in Computer Science, Information Security, Engineering, or a related field with 7+ years of relevant experience is required. • 5+ years of experience in application security, product security, or offensive security, including hands-on threat modeling and secure design for complex systems, is required. • Practical, demonstrated experience assessing or attacking AI/ML or LLM systems (e.g., prompt injection, model abuse, data exfiltration via LLMs, or adversarial examples) is required. • Experience working within or alongside regulated industries with compliance obligations (e.g., NIST AI RMF, SOC 2, ISO 27001) is preferred. • Experience with RAG pipelines, vector databases, or agent frameworks and their associated security risks is preferred.
