As MISO’s Senior Security Architect, you will lead the design, implementation, and ongoing enhancement of secure architectures across enterprise systems, applications, and cloud environments. This role provides expert guidance on current security challenges while anticipating future trends to proactively shape strong, resilient solutions. You’ll think like an adversary, ensuring security strategies evolve with the changing threat landscape. Strong communication and leadership skills are essential, as you’ll mentor team members and provide technical direction to delivery and solution design groups.

The architect contributes to threat modeling, reference architectures, and repeatable security patterns that reduce risk and improve consistency. Additionally, you will serve as a strategic advisor for secure digital transformation, aligning AI adoption, enterprise architecture, engineering, and compliance to ensure sustainable, business‑aligned security decisions.

• Staying current on emerging security threats, analyzing risks, and ensuring systems and applications are resilient against evolving threats.
• Engaging with vendors to ensure alignment with MISO security standards and defining guardrails for human‑versus‑automation decision‑making in security workflows.
• Delivering clear, executive‑ready risk narratives that translate architecture trade‑offs into business impact, resilience, and regulatory implications.
