Full Job Description
Every Mariana Minerals site runs on a production plan, and this role brings them together. As our first Production Planner, you'll partner with each site to develop its plan, then roll those plans up into one clear view across the company.
You'll build our planning tools in MarianaOS, either with tools our software team develops or by building your own with AI. If you love building systems and learning new ways to work, you'll thrive here.
You'll also own KPIs and drive operational excellence across our sites, tracking productivity, cycle times, and costs, and finding ways to improve them. This role reports to our COO and sits at the intersection of operations, data, and OpEx. You'll build the playbook, and you will help shape the foundation of a central OpEx team.
This role is for someone scrappy, data-driven, and highly collaborative, who's excited to build systems from the ground up.
