Job description

Company Overview

At Renasant Bio, we are driven by a singular goal: to change what’s possible for patients with kidney disease. ADPKD remains one of the most challenging areas in medicine, and we believe it requires bold thinking, rigorous science, and a team committed to doing things differently.

We’re looking for individuals who bring both scientific rigor and creativity to hard problems, and who believe great work is built through respectful, direct collaboration. You communicate with honesty and transparency, adapt quickly as priorities evolve, and hold yourself—and others—to a high standard. Above all, you operate with urgency and purpose, grounded in the knowledge that patients are waiting.

Based at Bakar Labs in Berkeley, CA with additional support in Cambridge, MA, we are advancing new therapies designed to make a meaningful difference for patients.

The Role

Responsibilities

• Collaborate with scientists to evaluate novel therapeutic candidates using transgenic mouse models, including target validation and mechanism of action studies.
• Oversee and maintain mouse colonies, including breeding, genotyping, colony expansion, and accurate inventory tracking of vivarium supplies.
• Perform routine in vivo tasks, including animal handling, dosing (PO, IV, IP, SC), blood and tissue collection, sample processing, anesthesia administration, and euthanasia as needed.
• Monitor animal health, maintain compliance with IACUC protocols, and ensure ethical standards in animal care.
• Provide detailed documentation of experimental protocols, observations, and results.
• Collaborate with multidisciplinary teams, contributing to discussions on in vivo models and study outcomes.
• Adapt to the evolving needs of the team and contribute to maintaining aggressive project timelines.

Qualifications

• Education: B.Sc degree in a relevant scientific field with 1-2 years of hands‑on experience in preclinical research or a bachelor’s degree with equivalent relevant experience. Industry experience is advantageous but not required.
• In Vivo Expertise: Proficiency in rodent handling required; experience with dosing techniques (e.g., IV, IP, SC), blood/tissue collection, and surgical techniques a plus.
• Mouse Colony Management: Demonstrated experience in managing transgenic mouse colonies, including breeding, genotyping, and maintenance.
• Laboratory Skills: Experience with in vivo sample processing and preparation for downstream assays such as histology or molecular analyses.
• Team Collaboration: Strong interpersonal skills with the ability to work collaboratively in a multidisciplinary environment.
• Organization: Exceptional attention to detail, organizational skills, and the ability to manage multiple tasks efficiently.
• Commitment to Safety: Adherence to laboratory safety and ethical standards in animal research.
• Flexibility: Willingness to adapt to team priorities and timelines in a fast‑paced environment.
