Job Description

This is a hybrid position that requires 3 days a week in our Boston office

Vertex is seeking an Associate Director, AI & Application Security to lead security for AI-enabled applications, platforms, and services across the enterprise. This role is responsible for securing AI throughout the full lifecycle-from design and development to deployment and ongoing operations-including generative AI, agentic workflows, traditional machine learning, and AI embedded in enterprise applications.

This leader will help define how Vertex securely adopts and scales AI across Azure, AWS, and GCP, as well as third-party and foundation model platforms such as Microsoft Copilot / Azure OpenAI, Anthropic, Google Gemini, and AWS Bedrock. The role will partner closely with technical and business stakeholders to establish pragmatic guardrails, strengthen secure development practices, and reduce risk without slowing innovation.

The ideal candidate brings deep expertise in cloud security and application security, along with strong judgment, technical credibility, and the ability to influence decisions in fast-moving, evolving environments. This role also requires practical experience applying security and risk frameworks relevant to AI and modern application environments.

* prompt injection and prompt abuse

* sensitive data leakage

* tool or action abuse

* unsafe outputs

* model misuse

* Define and mature AI guardrails, including monitoring, detection, logging, and misuse or negative testing practices.

* Establish secure development expectations for AI-enabled applications and services, including secure coding practices and appropriate separation of development and production environments.

* Build and lead application security testing practices for AI-enabled applications and supporting services, including SAST, DAST, automated scanning, and retesting processes.

* Partner with Cloud Security, Security Operations, Privacy, Legal, Data Science, and Engineering teams to align security controls with business, technical, and regulatory requirements.

* Influence architecture and platform decisions through practical, risk-based guidance that can scale with AI adoption.

* Communicate risks, tradeoffs, and recommendations clearly to both technical teams and senior leadership.
