## About the role

Mariana Minerals is a software-first, vertically integrated minerals company supplying the minerals critical to modern energy, AI, and defense technologies. Our data doesn't live in a vacuum — it comes off sensors, assays, lab benches, and plant logs, and it's what the business uses to decide what to run, what to buy, what to fix, and what to build next.

## What they're looking for

- 3–6+ years in data science, statistics, analytics, or a quantitative research role where you owned analyses that drove real decisions
- Deep applied statistics: experimental design, hypothesis testing, regression, uncertainty quantification — and the judgment to know which tool fits the question and which assumption you just violated
- Strong SQL and Python (pandas, statsmodels, scipy) — enough to get your own data, run your own analysis, and produce your own reporting without waiting on someone else
- Track record building reporting and dashboards people actually use, with the product sense to know what belongs on a dashboard versus in a memo
- Ability to work with messy, real-world measurement data — missing values, inconsistent sampling, instrument error — and be clear about what it can and can't support
- Exceptional written communication, much of this job is making a technical finding land with operators, engineers, and executives
