Your responsibilities include defining the next architectural steps that meet the needs of diverse user communities while integrating solutions into a cohesive, long-term roadmap. You will collaborate with business stakeholders to understand current and future operational needs, translating them into a clear OT vision and blueprint. You will align with stakeholders on architectural decisions and ensure adoption across the organization. Staying on top of OT-related initiatives and fostering strong collaboration with peers and stakeholders is essential—especially in the context of risk mitigation, compliance, and secure operations.
