Principal Architect - SAP End-to-End Functional Architecture

Job ID: 529979

CRH's Americas Materials business is the leading provider of building materials in North America.

The aggregates, asphalt, ready mixed concrete, paving and construction services we deliver are critical to building our world.

Our operations span 45 U.S.

states and two Canadian provinces with over 30,000 employees across 1,700 operating locations.

Position Overview

We are seeking a Principal Architect to oversee the end-to-end functional architecture for SAP across the enterprise.

Reporting to the SVP, Technology Transformation, this person is the senior design authority for how SAP supports the business across Order to Cash (OTC), Procure to Pay (PTP), Record to Report (R2R), Construction Accounting (CA), and Hire to Retire (H2R), and for how these end-to-end processes connect to each other and to the surrounding application landscape.

The ideal candidate combines deep functional expertise in at least one core process area (such as OTC or PTP) with broad working knowledge across the others: able to define the target-state architecture, make and defend design decisions, and keep process, data, configuration, and integrations consistent as the landscape evolves.

The role is hands-on enough to be credible with configuration, master data, and interface design, and to review custom development for quality and performance, but the emphasis is on functional architecture, governance, and outcomes rather than writing code.

The candidate has a proven track record architecting integrations between SAP and surrounding platforms such as Point-of-Sale (POS), Salesforce, eCommerce, and customer payment portals.

This is also a highly business-facing role: the successful candidate will work closely with Sales, Finance, Procurement, Operations, Logistics, HR, and technology leaders, translating current- and future-state process requirements into solution architecture, data models, and integration designs.

As principal architect, this person will lead architecture and design workshops, produce solution and design documentation, steer partner and vendor delivery, and mentor SAP functional and technical resources.
