Knowledge of operating and maintaining small boats, kayaks, outboard motors, and SCUBA certification are also advantages, but are not required.

Working Conditions and Physical Demands: Must be comfortable wading, snorkeling, diving, and boating in Texas streams, rivers, lakes, and bays that experience a wide range of conditions. Must be willing to work irregular hours on occasion, including weekends and evenings, in remote locations in inclement weather. This position will require travel to remote areas to conduct field work for several days at a time. Must have ability to work as part of a team with team members of varying backgrounds and skill levels.

Location: This position will be stationed in BIO-WEST’s San Marcos, Texas office.

Salary:  $55,000 – $70,000 annually to start is anticipated, but actual pay will be commensurate with experience, skills, education, and training.
