Mariana Minerals is a software-first, vertically integrated minerals company focused on supplying critical minerals for modern energy, AI, and defense technologies. The company is reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
As Staff Process Controls Engineer, you will lead the development and deployment of first-of-its-kind chemical refining processes while playing a critical role in developing software for capital project execution and automated plant optimization. Your scope spans the full lifecycle of equipment and plant-wide controls infrastructure—from concept and modeling validation through procurement, engineering, fabrication, installation, commissioning, ramp, and handover to operations.
Key responsibilities include: leading equipment scopes across the full project lifecycle; managing external equipment providers, technology licensors, and engineering firms to deliver integrated mineral refining systems; driving cross-functional teams of lab technicians, pilot plant engineers, process engineers, and project engineers to scale novel refining processes and de-risk commercialization; hiring, mentoring, and managing junior engineers; leading selection, procurement, calibration, and installation of instruments, valves, and analyzers; supporting machine learning applications for industrial control and optimization; and identifying opportunities for software and ML teams to automate capital project workflows and develop advanced plant control algorithms.
You bring strong engineering fundamentals and demonstrated problem-solving ability. Required experience includes equipment engineering and design (brownfield modifications, greenfield design, equipment evaluation and optimization, operations support); minimum 7 years in networking and systems administration for control systems (network architecture design, fiber installation, Ignition expertise, plant network management with secure business network interfacing, P&ID review, control system programming); experience in industrial manufacturing, large-scale mining/mineral processing, chemical production, or EPC firms; and direct or indirect leadership of engineers and technicians. You have managed medium to large-scale (>$5M) capital projects.
