Hydrogeologist

Tetra Tech is seeking an entry-level Geologist/Hydrogeologist for our Superior or Longmont, Colorado offices. The position is intended for candidates at the beginning of their professional geology/hydrogeology career, typically with zero to two years of directly relevant geoscience experience. Relevant experience should be primarily in geology, hydrogeology, environmental geoscience, or closely related groundwater-focused work. Primary work will involve groundwater investigations, hydrogeologic site characterization, drilling and monitoring-well programs, groundwater monitoring and sampling, hydrogeologic data interpretation, groundwater modeling, and related technical reporting.

The ideal candidate will have a strong academic foundation in geology and groundwater hydrogeology, an interest in developing a career in environmental hydrogeology, and strong computational and technical skills. Prior environmental consulting experience is preferred but is not required. Proficiency with databases, ArcGIS, and groundwater modeling tools, including finite-difference and/or finite-element modeling approaches, is preferred. Attention to detail, strong oral and written communication skills, and the ability to quickly learn new technical skills are required.

The successful candidate should have a strong work ethic, a positive attitude, and the ability to work effectively both independently and as part of a team.
