This is a great opportunity to join Calibre Scientific as the ERP Transformation Director. The role is the in-house SAP technical authority for the S/4HANA platform and its connected systems.
Calibre operates a vendor-delivered model. Application Management Services (AMS) and project implementation are provided by third-party partners. This role owns the technical direction those partners work to, and holds them accountable for what they deliver.
The ERP Transformation Director owns the target solution architecture, defines technical standards, approves significant designs before build, and acts as the escalation point for complex issues that vendor support cannot resolve.
Deep, current S/4HANA system knowledge is essential. The role is expected to read and challenge vendor designs, configuration and code, and to be credible in technical debate with delivery partners.
