In Vivo Scientist (Night shift)

About the role

We are a vibrant and intensely mission-driven team in San Francisco, comprising members from MIT, Harvard Medical School, Roche, ETH, and Dana-Farber. We value speed and rigor, coupled with excitement, drive, and a strong work ethic. In an early-stage environment, we value people who can bring clarity to open-ended problems, take ownership of the next steps, and follow through with energy. Capable Labs is a place for ambitious, high-integrity people who want to become dramatically better. You will be surrounded by people who care intensely about the work, get close feedback from the people making scientific and company-defining decisions, and have room to own increasingly important problems. We believe excellent work should be met with meaningful reward, ownership, and trust. Responsibility is earned through contribution, not title alone: anyone who demonstrates the judgment, rigor, and follow-through to move important work forward can earn meaningful scope.

You are specifically looking for or open to a night-shift lab role. You are comfortable working overnight hours, operating independently during quieter lab periods, and handing off clean, well-documented work to the day team.

Responsibilities

• Assist with running mouse studies to help evaluate potential new therapies for safety and effectiveness.
• Help dose mice using different methods, such as IP, IV, SC, PO, and intranasal, following study guidelines.
• Assist with collecting samples, including blood and tissues like liver, kidney, spleen, lung, brain, muscle, heart, tumor, and other relevant organs.
• Support the team during surgeries and special in vivo procedures, with training provided as needed.
• Perform EEG surgeries in mice and support EEG studies.
• Perform basic animal husbandry, dosing mice using common routes (such as IP and IV).
• Attend to routine vivarium duties, including cage cleaning, bedding changes, restocking supplies, and monitoring animal health and welfare.
• Ensure compliance with established protocols and maintain a clean, organized, and well-functioning vivarium environment.
• Work efficiently and reliably, paying careful attention to detail, and make documented judgment calls when needed.
• Coordinate cleanly with day shift team members and provide handoffs.

Qualifications

You have experience working with laboratory animals, ideally in biotech, pharma, academia, or a related environment.

Pay & Benefits

• $500+ monthly wellness budget for training, supplements, coaching, recovery, or other tools that help you perform at your best.
• Healthcare: We offer a broad range of medical, dental, and vision coverage options, with Capable covering 100% of the base policy. You will also have access to HSA, FSA, and 401K plans.
