About The Position

We are seeking a Senior Manager, Enterprise Architecture, to join our Information Technology organization, based in Toronto/Sudbury, ON. This is a permanent, hybrid position, operating in a complex, global, and industrial environment, where enterprise IT, operational technology (OT), and industrial systems must work seamlessly together. This role is execution-focused and works directly with operational sites, capital projects, and delivery teams. It is not a strategy-only or purely governance role—you will shape and deliver practical, resilient, and fit-for-purpose architectures that support how work truly happens across our business. You will report to the Head – Governance and Architecture and act as a key technology partner to business leaders, engineering teams, cybersecurity, data & analytics, and operational stakeholders across the organization.

Requirements

• 11–15 years of progressive experience in enterprise, solution, or systems architecture
• Significant experience in industrial, mining, manufacturing, utilities, or other asset‑intensive environments
• Proven experience designing and integrating IT, OT, and industrial systems
• Experience working across global, distributed, and site-based teams
• Bachelor’s degree in Information Technology, Computer Science, Engineering, or a related field
• Strong understanding of enterprise platforms (ERP, EAM, finance, supply chain, HR)
• Working knowledge of OT systems (SCADA, DCS, PLCs) and industrial applications
• Experience with IT/OT integration, industrial networking, data architectures, and cybersecurity principles
• Ability to think end‑to‑end across business processes, systems, and data
• Comfortable creating detailed architectural documentation and working hands‑on with engineers and vendors
• Strong stakeholder engagement and influence skills
• Pragmatic, execution-oriented, and outcomes-focused mindset
• Strong safety awareness and disciplined approach to risk management

• Own and evolve end‑to‑end business process architectures aligned with the company’s operating model
• Identify gaps, inefficiencies, and risks across processes that span corporate IT and operational environments
• Ensure architecture reflects real site conditions, safety constraints, and regulatory requirements
• Design how enterprise IT systems (ERP, EAM, Finance, HR), OT systems (SCADA, DCS, PLCs), and industrial applications (MES, historians, LIMS) work together
• Define pragmatic integration patterns, reference architectures, and interaction models
• Ensure secure, reliable data flows from field systems to enterprise analytics and decision platforms
• Engage directly with mine sites, processing facilities, and operational teams
• Embed within capital projects and modernization initiatives to influence design decisions early
• Support OT modernization and brownfield integration while minimizing operational disruption
• Produce practical architectural deliverables (system diagrams, integration designs, reference implementations)
• Work closely with cybersecurity, data & analytics, automation, and ERP teams to co-design solutions
• Support delivery teams throughout build, testing, commissioning, and transition to operations
• Incorporate safety, cybersecurity, and regulatory considerations into architecture designs
• Support segmentation, redundancy, fail-safe designs, and operational resilience across IT/OT boundaries
• Identify recurring challenges and establish repeatable architectural patterns
• Capture lessons learned from incidents and projects to continuously improve designs
• Influence solution selection and procurement decisions aligned with target-state architecture.

Benefits

• Competitive compensation including a variable annual incentive plan
• Participation in a competitive Defined Contribution Pension package
• Comprehensive benefits package (company paid core coverage, health and dental coverage, flex accounts, disability plans, and optional insurances)
• Leave for all of life’s reasons (vacation, personal, sick, parental)
