Research Associate, In Vivo Pharmacology

Company Summary

Korro is a biopharmaceutical company focused on developing a new class of genetic medicines for both rare and highly prevalent diseases using its proprietary RNA editing platform. Korro is generating a portfolio of differentiated programs that are designed to harness the body’s natural RNA editing process to effect a precise yet transient single base edit. By editing RNA instead of DNA, Korro is expanding the reach of genetic medicines by delivering additional precision and tunability, which has the potential for increased specificity and improved long‑term tolerability.

Using an oligonucleotide-based approach, Korro expects to bring its medicines to patients by leveraging its proprietary platform with precedented delivery modalities, manufacturing know‑how, and established regulatory pathways of approved oligonucleotide drugs. Korro is based in Cambridge, Massachusetts.

We are collaborative and united by a common mission. We are building a company with extraordinary people with an audacious vision to create transformative genetic medicines for prevalent diseases. Our values – Rewrite the future, On the Cutting Edge, Better Together, Dynamically Different, Kindness and Integrity – form the fabric of the organization. They are reinforced daily and serve as key dimensions in the hiring process to help us ensure that Korro is a magnet for outstanding talent and a great place to work.

Join us as we redefine what’s possible in genetic medicine and work to make a lasting impact on human health.

Korro Bio is seeking a highly motivated Research Associate to join our In Vivo Pharmacology team. This is an exceptional opportunity to work alongside experienced scientists in a collaborative, cross‑functional environment as we advance transformative genetic medicines to improve the lives of patients.

• Conduct experiments to determine the efficacy of novel oligonucleotides in rodent models across a range of disease indications.
• Perform dosing via subcutaneous (SC), intraperitoneal (IP) and intravenous (IV) routes; monitor animal health, collect blood samples, harvest multiple tissues, and coordinate sample storage and analysis.
• Provide overall in vivo and ex vivo technical support for projects working to advance one or more experimental therapeutic compounds.
• Develop, optimize, and execute ELISA and hELISA assays to quantify target proteins, biomarkers and therapeutic candidates in biological matrices.
• Support bioanalytical method development activities for the measurement of drug concentrations and pharmacodynamic endpoints in plasma, serum, and tissue samples.
• Generate and analyze in vitro, in vivo pharmacology, and ADME (absorption, distribution, metabolism, and excretion) data to characterize compound exposure and pharmacokinetic/pharmacodynamic (PK/PD) relationships.
• Contribute to target engagement assessments by designing and executing appropriate biochemical and cell‑based assays to evaluate on‑target activity of RNA editing compounds.
• Collaborate cross‑functionally with Discovery Chemistry, Translational Biology, and DMPK teams to support exposure response analyses and inform compound progression decisions.
• Maintain meticulous records of all experimental procedures, raw data, and results in electronic laboratory notebooks (ELN).
• Effectively communicate experimental results, observations, and data summaries to team members and cross‑functional stakeholders through written reports and presentations.

• Bachelor’s degree in Biology, Biochemistry, Pharmacology, or a related life sciences discipline with 0-2 years’ experience.
• Knowledge of tissue processing and molecular biology methods including RNA purification, PCR, qPCR, sequencing, protein isolation, MSD, western blot.
• Hands‑on experience with mouse colony management (animal handling, health assessment), dosing techniques (IV, SC, and IP), blood collection (tail vein/submandibular and cardiac puncture), and tissue collection at necropsy for ex vivo analysis.
• Proficiency in standard laboratory techniques including cell culture, aseptic technique, and sterile handling of biological samples.
• Hands‑on…
