About Mariana Minerals
Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
As a Process & Lab Technician, you'll support safe, efficient and high-quality process development studies and analytical tests. You'll work closely with R&D and engineering to build, operate and maintain ore leaching columns, and you'll deliver timely, accurate and actionable chemical analysis of ore, process streams and final products. You'll play a critical role in bridging leaching research and lab analytics with plant operations, helping make sure processes are robust, efficient and ready for future development and scale-up. This is a hands-on production lab at a working mine, not a clean lab. Expect dust, noise, acid fumes and mud.

Drive ore handling including crushing, sorting by particle size, and taking representative samples
Prepare samples for analysis using techniques such as digestion, dilution, and/or filtration
Perform elemental and compositional analysis of solid and liquid samples using ICP, NMR, XRF, Titrator, or similar analytical techniques
Document analytical results in laboratory information systems and maintain clear experimental records and material metrics using digital tools and software
Follow strict environmental, health, and safety protocols
Desired Qualifications
Experience working in minerals processing, metallurgy, chemicals, specialty materials, or similar industrial environments
Familiarity with chemical processing (pumps, columns, instrumentation, etc) or crushing equipment (crushers, grinders, conveyors, sorters, etc)
Ability to read and follow SOPs, equipment manuals, and safety guidelines
Mechanical aptitude and ability to perform basic mechanical fabrication and troubleshooting
Hands-on experience operating analytical or similar equipment
Strong communication skills and willingness to collaborate across teams
Commitment to safety, accuracy, and operational excellence
Ability to lift up to 50 lbs and work on your feet for extended periods
