Fish Biologist / PBT Coordinator

Closing Date: Open until filled.

We are seeking to fill the position of PBT Coordinator (Parentage Based Tagging) with experience in coordinating teams for fisheries fieldwork and maintaining collection data in an organized manner. This research group is involved in many kinds of genetics studies related to salmonids and other fishes and has developed PBT hatchery baselines for Chinook, Sockeye, and Coho salmon and steelhead in the Columbia River. The PBT Coordinator will act as a liaison between the CRITFC staff of the Genetics Lab and other staff of the CRITFC departments of Fishery Science and Fish Management and external staff at hatcheries across the Columbia River Basin that represent state, federal, and tribal agencies. The PBT Coordinator will help to maintain a set of robust PBT baselines by coordinating technicians’ schedules and participating themselves in sampling at hatcheries; updating and coordinating PBT data across databases; facilitating feedback between hatchery managers and CRITFC staff to improve metadata and utility of the PBT baseline in Research, Monitoring, and Evaluation (RM&E) objectives; participating in outreach and communication of analytic results to hatchery managers to further understanding of the role of PBT in RM&E. The PBT Coordinator will need to understand and coordinate all aspects necessary to update PBT baselines each year (e.g., field collections, tracking tissue samples, organizing and uploading genotypes, and providing standard reports). This position will be based at one of the primary duty stations in Portland, OR or Hagerman, ID to complete duties that will require in-person work and the potential for partial remote work. The PBT Coordinator will be supervised by a Senior Fisheries Geneticist or Lead Geneticist, with support from CRITFC geneticists, biologists, and technicians.

CRITFC offers competitive compensation and an exceptional benefits package, including medical, dental, 401(k), 12 days of vacation (to start), 12 paid holidays, and paid sick time. We provide professional development opportunities, promote from within, and have a Native hiring preference as part of our commitment to our people. As a result, you will find a work environment that supports and inspires our shared goals of protecting the natural world and the tribal cultural connection to it.
