• Blending to maintain compliance with smelting, environmental and hygiene constraints
• Proactive management of feed variability and limit exposure
• Maintaining stock balances and supporting reconciliation processes
• Providing clear technical guidance to Operations on feed-related performance
• Supporting blending trials and continuous improvement initiatives

You will have the following skillset and attributes:
You understand how feed chemistry influences furnace stability, slag behaviour, off-gas performance and operational risk.
You will have:

• Degree in Metallurgy
• Degree in Chemical Engineering
• Strong Excel and data analysis capability
• Experience interpreting concentrate assays and blending to operating limits
• Ability to work effectively across Operations, Planning and Logistics
• Strong safety focus and practical problem-solving skills
