In Vivo Research Technician (Night Shift)

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. About the Role You will support mouse studies and vivarium operations on a dedicated night-shift schedule, enabling overnight timepoints and around-the-clock study execution. You will perform careful animal work, collect and preserve samples for the day team, monitor animal welfare, and leave complete, reliable handoffs. This role requires comfort operating independently during quieter laboratory hours. Responsibilities Execute overnight study activities, including scheduled dosing, observations, collections, and time-sensitive procedures. Dose mice using common routes such as IP, IV, SC, PO, and intranasal administration in accordance with study protocols and your training. Collect, process, label, track, and store blood and tissue samples so they are ready for day-team analysis. Conduct overnight animal-welfare checks, document observations, and elevate issues according to established protocols. Support surgeries and specialized procedures, including EEG studies, with training where appropriate. Perform routine husbandry and vivarium duties and maintain a clean, organized, well-stocked environment. Provide concise, complete morning handoffs covering completed work, deviations, animal-health concerns, samples, and open issues. Ideal Qualifications Able and willing to commit long-term to the designated night-shift schedule and operate independently when needed. Hands-on experience working with laboratory animals in biotech, pharma, academia, or a related setting. Comfort with basic husbandry, common mouse-handling or dosing procedures, and accurate study records. Sound judgment and the ability to follow protocols, document decisions, and elevate appropriately when the usual day-team contact is unavailable. Strong attention to animal welfare, sample integrity, cleanliness, and detail. The ability to work independently and hand off work clearly to the day team. Pay & Benefits In addition to the posted salary range, we offer generous equity options. Compensation will depend on the skills, experience, and scope of impact you bring. If your background, experience, or compensation needs fall outside this range, we are still open to a conversation based on the scope and impact you could bring. $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. Healthy dinners with the team are provided daily. We support visa sponsorship where appropriate, including O-1, H-1B, J-1, TN, and other employment-based pathways.
