Ability to work independently, manage multiple competing priorities, and operate effectively in a fast-moving, resource-constrained environment with limited direction
High degree of ownership and accountability
Experience in the mining, energy, construction, or other capital-intensive industry
Experience supporting large scale commercial contracting projects
May include limited travel expectations as needed.
