Senior Reliability Engineer
About The Position
The Senior Reliability Engineer ensures that fixed plant equipment reliability enables stable throughput and optimal metallurgical recovery. The role is responsible for developing a world-class reliability system to minimize downtime and accelerate the ramp-up of the 60,000 tpd (expanding to 90,000 tpd) copper ore concentrator and refinery. Acting as the key interface between Maintenance, Operations, and Metallurgy, this role ensures equipment performance aligns with production targets and total business value. This role will be located at the Copper World Project, approximately 45 minutes southwest of Tucson near Sahuarita, Arizona.
Requirements
- University degree in Mechanical, Reliability, Industrial, or an equivalent Engineering discipline.
- A minimum of 6+ years of experience in Mining, mineral, or industrial operations, specifically within Reliability and Maintenance Engineering.
- Deep understanding of Reliability-Centered Maintenance (RCM) tools, asset lifecycle management, and fixed plant equipment such as mills, crushers, flotation circuits, and pumps.
- Proven ability to systematically evaluate the interaction between equipment performance, process stability, and business value.
- Strong analytical and problem-solving skills with the ability to translate technical issues into financial impact.
- Demonstrated cross-functional communication and leadership skills to influence collaboration across departments.
- Must be able to prove that he/she has a current and valid driver's license.
Nice To Haves
- Previous experience at a mine site is preferred.
- Deep proficiency in Reliability-Centered Maintenance (RCM) tools and asset lifecycle management, with a proven ability to integrate equipment performance with Process Control and Advanced Analytics to optimize metallurgical outcomes and business value.
Responsibilities
- Ensure reliability strategies support safe plant design and operation.
