• Evaluate loads, interfaces, materials, tolerances, and environmental conditions to ensure designs are robust and fit for real-world mining applications.
• Present and defend design concepts, trade studies, and recommendations to peers, stakeholders, and leadership.
• Analyze existing reliability, warranty, and field performance data to identify trends, recurring failure modes, and systemic design risks.
• Translate reliability insights into clear, actionable design requirements and design guidelines for new developments.
• Partner with reliability, quality, and data teams to process and interpret large datasets related to component and system performance.
• Support design risk identification activities such as DFMEAs, design reviews, and risk assessments, with emphasis on learning from historical data.
• Help define metrics, dashboards, and methods to track reliability performance over time horizons such as 1-year, 2-year, and 3-year service life.
