About You

• Degree in Mechanical Engineering (or equivalent).

• 6+ years' experience in mechanical design, construction, or operation of base-metal concentrators or large-scale process plants.

• Strong working knowledge of rotating and static equipment such as HPGRs, mills, flotation cells, thickeners, and pumps.

• Proven ability to manage installation, alignment, and commissioning of process plant systems.

• Experience working in EPCM or owner's team environments on major mining projects.

• Skilled in AutoCAD, SolidWorks, or 3D model review tools for mechanical design validation.

• Excellent communication, problem-solving, and leadership abilities, with a proactive and safety-focused approach.

This role offers the opportunity to be part of a career-defining project - a new, world-class copper-gold development.
You'll join a collaborative, high-performing team on a 6 weeks on / 3 weeks off rotation, working in a technically complex environment that will challenge and grow your expertise in mechanical engineering and large-scale plant delivery.
