Mechanical Engineer – Site-Based (FIFO)

We’re seeking a Mechanical Engineer to join a site-based team focused on whole-of-plant optimisation and sustaining capital delivery following a major expansion. This is a hands-on, site-driven role — not design or office-based. You’ll work across the full processing facility, including both legacy plant and newly installed circuits, identifying issues, improving performance, and delivering practical upgrades.

Key responsibilities include:

Walk down and assess the entire plant (not limited to a single circuit)
Identify reliability, operability, and maintenance improvement opportunities
Diagnose interface issues between legacy and newly installed infrastructure
Work with operations and maintenance to scope and prioritise works
Convert observations into practical, deliverable scopes
Support delivery of sustaining capital and minor projects
Review equipment and system performance across the plant
Contribute to shutdown planning and execution improvements

Typical focus areas:

Integration issues between old and new plant
Plant bottlenecks and system-wide inefficiencies
Maintainability and access improvements
Piping, pumping, and services optimisation
Recurring failure points and reliability issues
General plant optimisation across the full system

About you:

Mechanical Engineering degree
Strong site-based experience in mining or mineral processing
Background in fixed plant (pumps, piping, conveyors, etc.)
Experience across brownfield / sustaining capital work
Comfortable working directly with trades and supervisors
Able to identify issues and drive practical, implementable solutions

Ideal background:

Experience in gold, nickel, lithium, or similar processing operations
Exposure to whole-of-plant environments (not just single circuits)
Experience in ramp-up or post-commissioning environments

This role suits engineers who prefer site over office and can operate with a high degree of autonomy. Not suited to purely design-focused or early-career engineers. You’ll be working across a complex, integrated processing plant with an ongoing pipeline of optimisation and sustaining capital work, with direct impact on performance and reliability.
