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're hiring a Staff Product Manager to own the Engineering and Super domains of CapitalProjectOS (CPOS), the operating system for how Mariana designs, plans, and builds capital projects. CPOS is organized around four components ( MarianaEngineer (design), MarianaGSM (procurement), MarianaSuper (construction), and MarianaPM (planning and monitoring)) and this role owns two of them end-to-end: MarianaEngineer, the centralized system for design basis, process and engineering data, and 3D models; and MarianaSuper, the real-time command center for construction execution and plan-versus-actual tracking in the field.

You will be the single accountable owner for product strategy, roadmap, and execution across engineering and construction, working alongside PMs who own procurement (GSM) and planning/knowledge (PM) within the same CPOS team. The ideal candidate has hands-on experience in capital project engineering or construction/field execution and is energized by the challenge of embedding AI into workflows th
