As the chief field engineer, my day consists of making sure that all 240 remote sites are well maintained, running efficiently, and that data is coming in for scientists to analyze. Some sites are only accessible via helicopter, so sometimes travel to work can be interesting.

Tasks & Responsibilities May Include

  • Test and analyze samples to determine their content and characteristics, using laboratory apparatus or testing equipment.
  • Collect or prepare solid or fluid samples for analysis.
  • Compile, log, or record testing or operational data for review and further analysis.
  • Prepare notes, sketches, geological maps, or cross-sections.
