Senior Business Systems Administrator

The Senior Business Systems Administrator operates as a senior system administrator within the Business Applications team and partners closely with the Business Applications team and fellow NetSuite administrators to ensure NetSuite and related enterprise platforms such as Zip (procurement/sourcing) and Navan (time and expense) are leveraged effectively and consistently and in alignment with enterprise-wide standards and best practices. With NetSuite as the core ERP, this role leads the translation of complex finance, procurement, and accounting requirements into scalable system configurations, advanced workflows, and intuitive user solutions that drive operational efficiency, governance, and continuous improvement across the organisation. This position requires strong, hands-on expertise with procurement and time and expense platforms such as Zip, Navan, or similar tools, serving as the functional and technical owner of the end-to-end source-to-pay ecosystem.
The administrator provides strategic oversight and optimisation across sourcing, purchasing, invoicing, and expense management processes. Blending strong business acumen with deep systems expertise, the administrator operates as a trusted partner within the business applications team, ranging from system administrators to senior managers, influencing decisions and ensuring platforms function as strategic business assets rather than purely operational tools.

Maintain accuracy of core system data (approval hierarchies, spend thresholds, vendor records and GL mappings, to name a few) in line with documented standards.
Create and maintain test cases for assigned enhancements and fixes (including regression where applicable), and document outcomes to support release readiness and controlled deployments.
