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 information, visit www.terrestrialbio.com.

What You'll Do

• Develop, optimize, and execute cell-based functional and biological assays.

• Maintain and work routinely with mammalian cell lines and perform cell-base experimental workflows.

• Design and execute experiments with appropriate controls, replicates, and statistical

  considerations.

• Analyze and interpret experimental data using appropriate statistical methods, identify

  trends, and assess assay performance.

• Troubleshoot assays and contribute to improving assay robustness, reproducibility, and

  efficiency.

• Support analytical method development, qualification, and QC testing as projects progress.

• Maintain clear and accurate laboratory records and prepare data summaries and technical

  reports.

• Communicate results and scientific conclusions effectively within a cross-functional team.

Who You are

• Bachelor's degree with 3+ years of relevant experience, or Master's degree with 1-2 years of relevant experience, in Cell Biology, Molecular Biology, Biochemistry, Biotechnology, or a related field.

• 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.
