• Support factory-focused infrastructure architecture, including alignment between enterprise IT and OT/manufacturing environments.
• Review proposed infrastructure solutions and validate that designs support reliability, scalability, cybersecurity, and business continuity.
• Identify infrastructure risks, technical gaps, and non-standard designs; elevate where needed and recommend mitigation plans.
• Ensure global infrastructure governance is balanced appropriately with local, regional, and factory operational needs.

• Coordinate ordering and infrastructure demand related to on‑premises server environments, hybrid platforms, and cloud-hosted services.
• Support planning and governance across on-prem, hybrid, and cloud infrastructure landscapes.
• Ensure infrastructure architecture and service delivery comply with cybersecurity requirements, internal controls, and company standards.
• Partner with cybersecurity teams to identify, assess, and address infrastructure-related risks.
• Promote secure and resilient infrastructure practices across factory, office, and multi-site environments.
• Act as an infrastructure escalation point during major incidents, partnering with site teams, service providers, and technical stakeholders to accelerate recovery.
• Drive or coordinate post-incident reviews, root cause analysis (RCA), and corrective action follow-up.
• Identify recurring issues and work with vendors and internal teams to reduce incident frequency and improve service stability.
