  • Conduct acid washing and cleaning of labware to maintain lab standards.
  • Maintain sample and consumable inventory in the lab.
  • Support data collection, export, and organization from ongoing deployments, with a focus on alkalinity measurements

Desired Qualifications

  • Experience with wet chemistry techniques and general lab practices.
  • Familiarity with analytical instrumentation and lab equipment (e.g., I titrators, pH meters, balances, pipettes, etc.).
  • Strong organizational skills and attention to detail in sample handling and data documentation.
  • Basic understanding of data reduction and organization in Excel or Google Sheets.
  • Preference for candidates with experience in Python or an interest in basic data scripting.
