Job description

We are currently requesting resumes for the following position: SAP Solution Architect

Resume Due Date: November 16th 2026 (5:00 PM EST)

Number of Vacancies: 1

Duration: 12 months

Hours of work: 40 hrs

Location: Oshawa, 2 days onsite

About The Role

Ontario Power Generation (OPG) is modernizing its SAP landscape across a portfolio of transformation initiatives. You’ll be the architect who makes it work. The program brings together SAP S/4HANA, SAP Extended Warehouse Management (EWM), and Advanced Asset Management, some of the most complex software SAP offers.

You’ll lead end-to-end solution design and keep business requirements, SAP platforms, integration, security, data, and operations aligned with OPG enterprise architecture strategy. You’re also the technical gatekeeper. You’ll challenge, validate, and sign off on designs from systems integrators (SIs) before they’re built. Getting design right now prevents years of technical debt and rework.

What You’ll Do

• Lead solution architecture across SAP S/4HANA, Asset Management, Supply Chain, Finance, SAP Ariba, SAP Concur, and SAP Fieldglass.
• Guide delivery through the full lifecycle: discovery, fit-to-standard, design, build, integration, data migration, testing, cutover, deployment, hypercare, and transition to operations.
• Evaluate SAP configurations, review detailed designs, and validate technical and functional decisions.
• Design and troubleshoot cross-module processes, such as:
• Triggering an Ariba purchase requisition or purchase order directly from a Plant Maintenance (PM) work order for external services or spare parts.
• Managing maintenance spare parts through Materials Management (MM), from receipt to consumption.
• Matching contractor maintenance costs from the field with Concur Invoice or Ariba Services Procurement for automated financial settlement.
• Enforce SAP Clean Core principles. Use standard S/4HANA, Ariba, and Concur functionality first and keep custom ABAP code to a minimum.
• Review and approve SI technical designs, configurations, and integration plans.
• Maintain architecture documentation, portfolio views, dependency maps, and transformation roadmaps in LeanIX.
• Lead business stakeholders, internal technology teams, SIs, and vendors through architecture governance and delivery.

What you bring

• 10+ years of SAP experience, including at least five years as a Lead Solution Architect, Principal Consultant, or equivalent senior SAP architecture role (solution, technical, or functional).
• Solution architecture leadership on at least one large-scale enterprise SAP implementation or transformation program.
• One to two full-lifecycle implementations or migrations to SAP S/4HANA, with strong command of Fiori UX, embedded analytics, and the S/4HANA data model.
• Demonstrated experience with RISE with SAP and cloud or hybrid delivery models.
• A track record as the technical authority over external SIs and third-party vendors in complex, multi-vendor programs.

Modules

• At least seven years of hands-on design and configuration in SAP PM / Enterprise Asset Management (EAM). This includes work order management, preventive maintenance, technical objects (functional locations and equipment), and calibration.
• Deep expertise in SAP MM and Production Planning (PP), including inventory management, material requirements planning (MRP), and master data governance.
• Proven end-to-end source-to-pay (S2P) architecture, integrating SAP Ariba (Sourcing, Buying, and Ariba Network) with the ERP backend.
• Direct experience designing SAP Concur travel, expense, and invoice workflows, with clean financial postings and master data sync to SAP.
• Experience with SAP Finance and/or SAP Fieldglass.

Integration

• Strong hands-on experience with SAP Business Technology Platform (BTP) Integration Suite, including Cloud Integration Gateway (CIG).
• SAP-to-SAP and SAP-to-non-SAP integration design using API-led, event-driven, batch, and file-based patterns, plus OData APIs, IDocs, and EDI.
• Experience with integration security, monitoring, and support processes.

Tools and skills

• Experience using LeanIX for architecture documentation, portfolio management, dependency mapping, and roadmaps.
• Strong communication, facilitation, stakeholder-management, and architecture-governance skills.
