Strayer Education, Inc.

About The Position

If you're passionate about shaping the future of secure AI, cloud, and engineering at scale, this is your opportunity. Strategic Education Inc. (SEI)—a mission‑driven leader in workforce-aligned education—is seeking a Senior Principal Security Architect to help build what’s next. SEI empowers working adult learners through flexible, affordable, career‑relevant education across brands like Strayer University, Capella University, Sophia Learning, and Workforce Edge.

As SEI’s Senior Principal Security Architect, you’ll serve as the top technical authority for security architecture across AI, cloud, applications, and data platforms. This influential, hands‑on role partners directly with the CISO and senior engineering leaders to design secure AI/ML systems, architect multi‑cloud environments, drive DevSecOps transformation, and embed secure‑by‑design principles across modern engineering ecosystems. You’ll translate strategy into practical patterns, guide high‑impact enterprise initiatives, mentor teams, and strengthen the resilience and trustworthiness of the platforms powering SEI’s global learning experience.

Requirements

10+ years of professional experience in information security spanning multiple domains, including cloud, application, and platform security.
Proven experience designing and implementing large‑scale enterprise security architectures across modern engineering and cloud environments.
Deep technical expertise in cloud security (AWS, Azure, GCP), DevSecOps, secure SDLC, and modern application architectures (APIs, microservices, containers, Kubernetes, serverless).
Hands‑on experience or strong foundational understanding of AI/ML security, including risks such as data leakage, model manipulation, and supply chain vulnerabilities.
Strong ability to influence and collaborate with senior leaders, engineering teams, cloud operations, and cross-functional stakeholders.
Demonstrated capability to translate complex technical risks into clear business impact for executive audiences.
