• Lead security reviews and adversarial testing of LLM applications, AI agents, RAG architectures, machine learning services, and third-party AI integrations.
• Assess AI architectures covering model APIs, data pipelines, vector stores, prompts, fine-tuning workflows, plugins, and agent tool chains.
• Conduct adversarial testing for prompt injection, jailbreaking, sensitive-data disclosure, system-prompt leakage, output manipulation, insecure tool use, excessive agency, and model abuse.
• Evaluate risks related to data poisoning, model inversion, training-data extraction, adversarial evasion, and model exfiltration.
• Test AI security controls including guardrails, input and output filtering, access controls, human approvals, logging, monitoring, and abuse detection.
• Develop repeatable AI security testing methodologies, playbooks, automation, and test cases using tools such as Garak, PyRIT, or similar frameworks.
• Assess security and supply-chain risks associated with third-party models, AI platforms, and AI-enabled SaaS products.
• Produce clear security reports that document evidence, risk ratings, business impact, and actionable remediation recommendations.
• Communicate security risks effectively to developers, architects, product leaders, and executive stakeholders.
• Partner with external consultants, security researchers, and bug bounty programs when specialized assessments are required.
• Mentor engineers and contribute to building a strong, security-conscious engineering culture.
• Stay current with emerging developments in Application Security, AI Security, penetration testing, and adversarial testing.

• You have 8+ years of cybersecurity experience, with deep hands-on expertise in Application Security, product security, penetration testing, or security engineering.
• You have experience conducting threat modeling, architecture reviews, secure code reviews, penetration testing, and vulnerability validation.
• You have 1–3 years of experience in AI Security, AI/ML security, adversarial testing of AI systems, or applied AI research with a security focus.
• You have strong knowledge of web, mobile, API, and cloud-native security, including OWASP guidance and business-logic risks.
• You have a strong understanding of authentication and authorization technologies, including OAuth 2.0, OIDC, JWT, SAML, and modern access-control models.
• You have hands-on DevSecOps experience with CI/CD security automation, SAST, DAST, SCA, secret scanning, container security, and Infrastructure as Code.
• You have practical knowledge of Docker, Kubernetes, microservices, and cloud security.
• You have demonstrated experience assessing or securing LLM applications, RAG systems, AI agents, machine learning models, or AI-enabled products.
• You understand AI threats such as prompt injection, jailbreaking, data leakage, insecure tool use, excessive agency, model misuse, and AI supply-chain risks.
• You are familiar with OWASP guidance for LLM applications, MITRE ATLAS, NIST AI RMF, and related AI security practices.
• You have programming or scripting proficiency in Python, Go, JavaScript, Bash, or a similar language.
• You have strong written and verbal communication skills and can influence both technical and non-technical stakeholders.
• Experience building or scaling Application Security practices within a SaaS or product-led technology organization is preferred.
• Hands-on experience red teaming LLM applications, RAG systems, AI agents, or AI-enabled products is preferred.
• Experience developing security automation, internal testing tools, or reusable security guardrails is advantageous.
• Contributions to security research, open-source projects, bug bounty programs, or responsible vulnerability disclosure are valued.
• Relevant certifications such as OSCP, OSWE, GWAPT, GIAC, CISSP, or an AI Security credential are preferred.

• Remote-first working environment with opportunities to collaborate across a global organization.
• Professional development and opportunities to deepen expertise in Application Security, AI Security, penetration testing, and emerging technologies.
• Opportunities to contribute to security research, automation, secure engineering practices, and AI security initiatives.
• Opportunities to mentor engineers and influence security practices across technical teams.
• Exposure to large-scale cloud-native applications, APIs, microservices, AI systems, and modern security technologies.
• Collaborative culture focused on creativity, innovation, teamwork, and meaningful technical impact.
