About the Team & Role
WEX, Inc. is seeking a Senior Enterprise AI Security Architect to help define the vision, strategy, and provide technical leadership for defining the security strategy, architecture, and governance for Artificial Intelligence (AI) and Machine Learning (ML) across the global enterprise. This individual will serve as a high-level visionary, bridging the gap between business requirements and technical security execution. You will be responsible for designing resilient security architectures that protect WEX’s global assets and people, ensuring robust compliance, while enabling rapid innovation. The successful candidate will serve as a subject matter expert (SME), bridging the gap between Data Science, Software Engineering, and Cyber Security to build a robust Secure AI ecosystem.
We’re the Global Information Security Team at WEX, responsible for implementing and operating security technologies and processes throughout WEX. We don’t just operate security tools; we engineer trust. Our team partners with executive leadership and cross-functional engineering groups to ensure WEX is secure by design. We hold ourselves to a high standard of architectural excellence, ensuring that our security posture is proactive, scalable, and resilient.
We are looking for a Senior Enterprise AI Security Architect that is responsible for ensuring the secure function of software development, infrastructure deployment, and regulatory alignment.
How you’ll make an impact
A Strategic Thinker: You look beyond the immediate need to see the systemic challenge. You design for the next five years, not just the next five months.
A Consultative Partner: You can explain complex security trade-offs to non-technical stakeholders and influence senior leadership. A collaborative, solid communicator who works well with your team and stakeholders to drive projects from inception to completion
A Secure By Design Mindset: You value a "Secure by Design" philosophy and strive to integrate protection layers into the AI lifecycle without hindering the speed of innovation
