About the job
About Mariana Minerals
Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
The role
We are hiring a Cost Control Engineer to own the cost baseline, the forecast, and change control on Mariana's capital projects.
You will build the cost breakdown structure, convert the sanctioned estimate into a control budget, track commitments and actuals, and produce the forecast at completion that the business plans against. The role sits between engineering, procurement, construction, and finance — the path where a commitment becomes an accrual becomes an invoice becomes a capitalized asset — and your job is to make sure the number is the same in all four places. Cost control here is not a monthly report assembled by hand. The reporting is expected to come out of the system and building that pipeline is as much the job as running it.
