Act as primary infrastructure lead during project BSF, coordinating network and hosting activities between site management, project teams and Global IT while ensuring infrastructure readiness (network, connectivity, hosting, security) to support all project milestones and commissioning activities.

Drive alignment between project design and corporate standards, including architecture reviews and approvals. Support site deployment activities including assessments, design validation, cutovers, testing, and go‑live.

Coordinate integration of network and hosting platforms (on‑prem, hybrid, cloud) into end‑to‑end infrastructure solutions & ensure systems are designed for high availability, security scalability, and operational sustainability.

Govern and coordinate external service providers, system integrators, and network vendors. Review designs, proposals, and delivery quality of suppliers.

Ensure compliance with GxP, data integrity, and cybersecurity standards (e.g., IEC 62443, ISO 27001) and support audits, risk assessments, and regulatory inspections.

Maintain architecture documentation, standards, and validation‑relevant deliverables.

Transition into on‑site owner for IT run services after project go‑live by defining and establishing support models, runbooks, monitoring, escalation paths, and service KPIs.

Drive network standardization, modernization, and lifecycle management.

Your profile:

Extensive experience in network architecture and infrastructure design in enterprise and industrial GxP environments with strong hands‑on expertise in LAN, WAN, WLAN, SD‑WAN, routing, switching, firewalls, and network security.
