The Opportunity

We are currently seeking a Principal Engineer to join the Vale Base Metals Geotechnical Team based in Sudbury, Ontario, Canada.

This is a permanent, onsite position and requires travel as required.

As the Principal Engineer, you will play a critical technical leadership role in the design, implementation, and optimization of underground backfill systems that support safe, reliable, and efficient ore extraction. This role requires deep knowledge of mine design, geotechnical constraints, underground mining practices, and backfill technologies, including paste fill, hydraulic fill, and rock or aggregate fill.

You will collaborate closely with mine technical services, operations, safety, procurement, suppliers, and other stakeholders to coordinate backfill schedules, optimize system performance, support quality assurance and quality control practices, and ensure backfill systems are aligned with safety, production, quality, and regulatory requirements.

This is an exciting opportunity for an experienced underground mining and backfill professional to influence mine stability, production performance, operational reliability, cost effectiveness, and continuous improvement across critical underground operations.

Backfill Strategy, Design & Technical Leadership:

Lead the technical direction and continuous improvement of underground backfill systems to support safe, efficient, and productive mining operations.

• Develop, implement, and optimize underground backfill systems, including paste fill, hydraulic fill, and rock or aggregate fill.
• Evaluate and approve engineering designs related to backfill systems.
• Partner with mine technical services and operations teams to coordinate backfill activities and integrate them into mine planning.
• Lead backfill-related projects and continuous improvement initiatives.
• Provide expert technical advice, consultation, and troubleshooting support.
• Establish and maintain specifications for backfill products, elements, and systems.
• Evaluate and approve new backfill products, designs, and technologies.
• Review, maintain, and update Backfill Management Plans.
• Support knowledge sharing, training, and development in backfill technologies and practices.
