The role

Mariana Minerals is looking for a Sr. or Staff Software Engineer, Infrastructure to join the team that owns and collaborates on the platform every other engineer here builds on.

Our software team builds MarianaOS, the operating system for how Mariana engineers, constructs, and operates its mines and mineral processing facilities. It runs in AWS and on edge clusters at our sites, including our copper site in Moab, Utah and our lithium facility in East Texas. On any given day, it serves construction dashboards, running GPU inference on site camera feeds, training models for a lithium extraction circuit, and moving plant floor data into a warehouse.

Your team owns the platform underneath all of that: clusters, deployment, CI/CD, observability, site/edge footprint, identity, secrets, and cloud costs. You will also collaborate with machine learning engineers and data engineers on the ML compute platform and data pipeline infrastructure.
