• Release parts and assemblies into the production system, supporting all required documentation and processes.
• Participate in and support improvements to streamline engineering processes used to design, develop, maintain, and support components, products, and/or services.
• Take ownership of your personal development by actively building technical skills and seeking feedback to continuously improve performance and contributions.

• Bachelor of Science Degree in Engineering or equivalent relevant discipline, required.
• Minimum 8 to 12 years of experience in engineering analysis, design, machine application, mining industry, desired.
