IT Manager, Network Engineering

IT Manager, Network Engineering ABOUT MARIANA MINERALS Mariana Minerals is not a software company selling to mining companies. We are a mining company that builds software.

Our first commercial-scale lithium production facility, Lithium One, is targeting production in the first half of 2027. The software — what we call MarianaOS — exists to make our projects come online faster and run better. We don't sell it. We deploy it into our own operations and measure its impact in tons of metal produced, dollars of cost removed, and months shaved off construction timelines.
