Staff Mobile Equipment and Fleet Engineer

The role

Mariana Minerals is seeking a Mobile Equipment and Fleet Engineer to build and optimize the equipment fleet for our open pit mining operations. You will own the technical specifications, equipment and OEM selection, and full lifecycle economics of production and support equipment. Autonomy is a central part of the role: you will help determine which equipment should operate without an onboard operator, how to achieve that through new purchases or retrofits, and how to integrate autonomous machines into a productive mine.

What you will do

What You'll Do

Fleet selection and autonomy
Design the fleet. Translate mine plans, production targets, haul profiles, ground conditions, road geometry, operating hours, and site constraints into fleet requirements. Match loading, hauling, drilling, and support equipment so the fleet performs as an integrated system.
Specify and select equipment. Develop technical specifications and compare machine classes, models, powertrains, configurations, and OEMs. Evaluate payload, cycle time, availability, maintainability, parts and dealer support, interoperability, and readiness for remote or autonomous operation.
Drive the autonomy roadmap. Identify where autonomous haulage, loading, drilling, and support equipment can create practical value. Compare purpose-built autonomous machines with retrofit options, including whether and when removing the onboard operator makes technical, operational, and economic sense.
Engineer autonomous integration. Work with OEMs, autonomy vendors, site teams, and software developers on machine controls, sensors, communications, fleet coordination, remote supervision and intervention, and interfaces with dispatch and maintenance systems. Define acceptance tests and support safe commissioning.
Make autonomy work in the field. Plan for interactions among autonomous trucks, loaders, drills, manually operated equipment, and people. Evaluate the effect of autonomy on haul roads, loading areas, traffic rules, fueling and servicing, recovery procedures, productivity, and staffing.
Lifecycle performance and data
Own lifecycle economics. Build and maintain models for acquisition, fuel and energy, tires, maintenance, major components, rebuilds, autonomy conversion, replacement, and residual value. Use cost per tonne and project value to guide purchase and replacement decisions.
Improve equipment life and performance. Partner with operations and maintenance to address downtime, underutilization, payload losses, inefficient operation, and premature wear. Use condition monitoring and operating data to improve maintenance plans, equipment use, and rebuild timing.
Build with data and software. Define telemetry and data collection needs, connect equipment and maintenance information, and work with the MarianaOS team to develop tools for fleet selection, equipment health, utilization, autonomous performance, and continuous optimization.
Guide OEM and vendor choices. Assess technical capability, autonomy offerings, integration flexibility, service coverage, parts availability, and long-term support. Stay current with advances in engines, powertrains, controls, and mining automation.

What Success Looks Like

Mariana has a fleet selected for the actual requirements of each operation, with clear specifications and defensible lifecycle costs. Autonomous equipment is deployed where it improves the operation, with proven integration into the broader fleet. Equipment data informs daily performance improvements and future fleet decisions.
