About this role
Scientist I, Bioassay
Terrestrial Bio
Location: Allston, MA and Woburn, MA
About Terrestrial Bio, Inc.
Terrestrial is transforming the delivery of next-generation therapies, starting with GLP-1.
Terrestrial's 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
