Master Data Specialist - Remote

Job Summary

Oldcastle Infrastructure (OI), as part of CRH’s Infrastructure Products Group (IPG), is a global manufacturing leader of utility infrastructure products. Our goal is to be the most efficient producer of engineered systems and our customers’ strategic partner of choice. A crucial part of OI’s journey is the investment in a new ERP system. With a modern, common platform, OI will unlock the benefits of its scale, deliver a better customer experience, and build a foundation for continuous process improvement.

We are seeking a Master Data Management (MDM) Specialist to support both ongoing ERP conversion initiatives and steady-state master data governance in a dynamic, manufacturing-focused environment.

This role is ideal for a business-minded SAP professional who understands how master data drives operational execution — not just how to enter it. You will partner with business SMEs, technical teams, and data leadership to construct, analyze, migrate, and maintain high-quality master data within SAP S/4

HANA.

Depending on experience and business needs, this role will focus on one primary domain:

• Material Management
• Business Partner (Customer/Vendor/Employee)

Our team operates in a hybrid model of recurring conversion waves (every ~90 days) and continuous process improvement initiatives. This role flexes between implementation-focused work and operational MDM support.
