Instrument Engineer, On Call

Capable Labs • San Francisco, CA

14h • Onsite

About The Position

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 keep the instruments behind Capable’s chemistry lab running around the clock. Our chemists synthesize and purify new compounds every day on microwave synthesizers, parallel synthesizers, flash and prep HPLC, evaporators and LC/MS. You will diagnose and repair failures quickly, run preventive maintenance, and install new equipment as the lab grows, working closely with chemists to keep their work moving and to help decide what we buy next. This is a contract role, on site in San Francisco, with on call coverage nights and weekends.
