What We Do At Weir We are a global leader in mining technology for a sustainable future. We help our customers extract the resources the world needs more efficiently and more sustainably. Our planet’s future depends on the transition to renewable energy, and that transition can only happen with the metals and minerals our customers deliver. So, we work side by side with mines across the globe to move less rock, use less energy, use water wisely, and create less waste. Together, we drive the shift to smart, efficient, and more sustainable mining.

What You'll Do

• Audit Planning: Lead risk-based scoping and objective setting, confirming criteria, materiality, sources of assurance, and required resources. Conduct planning walkthroughs with process owners to identify key risks and controls, agree on data needs, timelines, and logistics. Document planning decisions to maintain conformance with methodology and professional standards.
• Audit Delivery: Obtain sufficient, reliable, and relevant evidence using appropriate testing, analytics, and sampling techniques to meet engagement objectives. Evaluate control design and operating effectiveness; determine root causes and quantify risk/impact where practicable. Maintain complete, timely workpapers supporting conclusions and conformance. Review and coach auditors’ workpapers for clarity and sufficiency.
• Audit Supervision: Supervise auditors in the completion of audit engagements: assessing work, providing coaching notes, performing reviews, reviewing ‘points for discussion'.
• Reporting & Influence: Produce concise, decision-ready reports clearly outlining condition, cause, consequence, and criteria with prioritized recommendations. Secure agreement on actions, accountable owners, and realistic due dates; escalate where material risk persists. Build trusted relationships with senior stakeholders while maintaining independence and objectivity.
• Follow-Up & Validation: Track agreed actions to due date and validate closure with evidence. Report implementation metrics including on-time, aged/overdue, and repeats to audit management.
• Digital, Analytics & AI: Champion data-enabled auditing by defining hypotheses, obtaining ERP/operational data, and using Excel/Power BI (or similar) to focus testing, surface anomalies, and quantify impact. Use GenAI responsibly with human review and preserved audit trail, consistent with standards and governance.
• Quality & Continuous Improvement: Contribute to the Quality Assurance & Improvement Program (QAIP) through self-assessments, lessons learned, and method updates. Share tools, templates, and analytics techniques to improve efficiency and insight across the team.
• Audit Agility: Lead initiatives to foster the Internal Audit team’s agility, collaboration, and digital enablement in delivering insightful forward-looking reports, which address current and emerging risks.
• Safety First: Demonstrate 100% commitment to our zero harm behaviors in support of our drive towards developing a world-class safety culture.
