Sap / architect - production planning

Oldcastle Infrastructure, a CRH company, is the leading provider of utility infrastructure solutions for the water, energy, and communications markets throughout North America. With more than 80 manufacturing facilities and over 4,000 employees, we lead the industry with innovation and a safety‑first mindset.

The SAP Functional Architect - Plan‑to‑Produce drives the architecture of manufacturing planning and execution processes within SAP, ensuring that production workflows from demand planning and MRP through shop‑floor execution operate with high performance, accuracy, and reliability. As the design owner for PTC, the Architect defines production models, master data frameworks, capacity planning parameters, and integration logic with cross‑functional modules and or systems where required. The Architect works closely with the Product Owner to translate business requirements into robust, scalable designs that uphold clean‑core principles and support multi‑plant operations. This role plays a key part in enabling production efficiency, operational visibility, and continuous improvement through well‑architected processes, testing frameworks, and stable deployment practices.

This role will work hybrid out of our office in the Sandy Springs, GA area.

Strategy, Architecture & Standards

Own the PTP target state for all plants (MTS, MTO, ETO or Repetitive, as applicable) using standard SAP PP capabilities, document scope, constraints, and variants.

MRP runtime windows, posting latency, job concurrency) and operability standards (logging, monitoring, error handling) within S/4HANA.

Master Data Governance (Build‑Once, Reuse Everywhere)

Govern BOMs, Routings, Work Centers, Production Versions.

Standardize planning parameters (lot sizes, safety stock, planning strategies, lead times, scheduling margins) by product family/plant.

Define material master rules for PTP‑relevant views and ensure alignment with PTC, OTC and RTP.

enforce SoD around master data vs. execution.

Ensure auditability for order changes, confirmations, yield/scrap edits, and routings/BOMs; Testing & Quality Assurance

Demand → MRP → Order → GI → Confirmation → GR → QM → FI/CO postings (incl. Provide SIT/UAT scripts for high‑volume flows, constraints (finite capacity where used), and edge cases (shortages, substitutions, partials).

Establish dress rehearsal criteria (mock MRP, pilot orders, stock adjustments) and production validation steps (first‑article checks, day‑1 throughput).

Drive root‑cause and permanent fixes.
