Research Associate, Functional & Biological Assays

About Terrestrial Bio, Inc.

Terrestrial is transforming the delivery of next-generation therapies, starting with GLP-1. Terrestrials proprietary Tacterra microarray patch (MAP) and applicator platform consists of a patch resembling an adhesive bandage, which is applied with a preloaded applicator and removed after a few minutes. Once applied, each patch delivers bioactive tips into the skin, which dissolve quickly into the body, rapidly releasing their therapeutic payload. Designed for self-administration, the temperature- stable Tacterra platform enables precise, controlled delivery of a wide range of therapeutics without medical sharps or refrigeration.

Terrestrial has generated strong clinical and in-vivo proof of concept across multiple molecules. For more information, visit www.terrestrialbio.com.

• Hands-on experience with mammalian cell lines is required.

• Experience with functional, biological, or cell-based assays.

• Strong understanding of experimental design, controls, data analysis, and interpretation.

• Ability to work independently, troubleshoot experiments, and manage priorities in a fast-

paced laboratory environment.

• Strong attention to detail and commitment to accurate scientific documentation.

Nice to Have

• Experience with analytical method development or method qualification.

• Experience with HPLC or other analytical techniques.

• Experience working in a GLP/GMP or Quality Control environment.

• Experience with assays such as ELISA or other quantitative biological assays.

Compensation: The anticipated base salary range for this position is $75,000 - $90,000. Actual compensation will be determined based on a variety of factors including experience, qualifications, and internal equity.
