Castle Biosciences Inc. is growing, and we are looking to hire a Clinical Research Scientist working from laboratory in Scottsdale, AZ, with a start date on or before November 1, 2026.
As a Clinical Research Scientist, you will serve as a primary technical resource for assay-related troubleshooting, data review, feasibility assessments, and testing questions. You will work closely with R&D when new samples, study concepts, or potential projects are introduced, helping translate those ideas into practical protocols and effective data-collection plans.
