MarianaOS Product and Workflow Development

Work directly with the software team to design, test, and improve MarianaOS tools for drilling, exploration, sampling, QA/QC, assay review, and resource modeling.
Translate field drilling workflows into product requirements, user stories, data models, automation logic, and practical software specifications.
Help define how technical users should plan drill programs, capture field data, track sample movement, validate assays, and reconcile results inside MarianaOS.
Build and refine workflows that reduce manual spreadsheet work, improve data quality, and make geological and drilling decisions faster and more auditable.
Serve as the domain expert connecting geologists, drillers, resource modelers, field teams, and software engineers.

Drilling Automation and Program Optimization

Help develop automated systems for drill planning, target prioritization, hole design, drill schedule tracking, contractor coordination, and field progress reporting.
Support workflows for greenfield exploration, brownfield drilling, infill drilling, resource conversion, confirmation drilling, and follow-up drilling.
Design repeatable logic for comparing planned versus actual drilling outcomes, including drilled meters, productivity, sample recovery, deviations, delays, costs, and geological results.
Identify opportunities to automate recurring decisions and checks across drilling campaigns, including sample interval validation, QA/QC flags, assay status tracking, and field issue escalation.
Partner with technical and software teams to turn field learnings into product improvements that can scale across future Mariana Minerals projects.

Sampling, QA/QC, and Field-to-Lab Workflows

Help define and automate end-to-end sample workflows, including sample interval design, labeling, chain of custody, dispatch, lab status tracking, assay receipt, and QA/QC review.
Develop requirements for automated QA/QC checks involving standards, blanks, duplicates, check assays, contamination risks, sample swaps, missing intervals, and out-of-sequence results.
Review drilling and sampling processes in the field and convert those observations into better systems, forms, controls, dashboards, and alerts.

Geology, Assay Interpretation, and Resource Model True-Up

Support automated comparison of drill results against geologic interpretations, resource assumptions, block model predictions, and mineralized domains.
Help develop drillhole-to-block-model reconciliation workflows covering lithology, stratigraphy, mineralized intervals, grade, thickness, alteration, and spatial continuity.
Define variance thresholds, validation logic, exception reports, and follow-up drilling recommendations.
Use assay results, field observations, and model outputs to identify areas where the model is confirmed, contradicted, or needs geological true-up.
Help create repeatable workflows that connect exploration drilling, resource estimation, mine planning, and project development decisions.

Cross-Functional Implementation and Adoption

Act as a bridge between field users and software developers, ensuring tools are technically sound, usable, and grounded in real exploration and drilling workflows.
Test new MarianaOS features with real project data, identify edge cases, document gaps, and provide actionable feedback to the software team.
Develop templates, process maps, standard operating procedures, dashboards, and training materials for drilling and sampling workflows.
Communicate clearly with geology, resource modeling, operations, product team, engineering, and leadership teams.

Copper One Field and Technical Support

Support drilling, exploration, sampling, and resource definition workflows for the Copper One project, a sedimentary copper deposit in the Lisbon Valley district of southeast Utah.
Spend time at site to understand actual field execution, contractor workflows, sample handling, geological controls, and operational constraints.
