• Define pragmatic integration patterns, reference architectures, and interaction models
• Ensure secure, reliable data flows from field systems to enterprise analytics and decision platforms

Site & Capital Project Engagement

• 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

Architecture Delivery & Enablement

• 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

Risk, Safety & Operational Resilience

• Incorporate safety, cybersecurity, and regulatory considerations into architecture designs
• Support segmentation, redundancy, fail-safe designs, and operational resilience across IT/OT boundaries

Continuous Improvement & Standardization

• 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.

Experience & Education:

• 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
• College Diploma considered with equivalent experience

Skills:

• 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

What We Offer You:

• 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)

• Employee Family Assistance Program
• Virtual Healthcare online
• Online training and career development opportunities
