Scientist II

Multiply Labs is a cutting‑edge startup based in San Francisco, California, supported by top-tier tech and life science investors such as Casdin Capital, Lux Capital, and Y Combinator. Our mission is to build the best robots in the world, and use them to make the most advanced life‑saving therapies accessible to all.

We are revolutionizing the manufacturing of cell therapies by developing advanced robotic systems designed to automate and scale the production of these life‑saving treatments. Our robots empower biopharma companies to produce cell therapies at scale without significantly changing their existing processes, reducing regulatory barriers and risks. While traditional approaches are time‑consuming and lead to extremely high costs for patients (typically $1M+ per patient), using robotics can make these transformative treatments more accessible and affordable to patients in need.

We are seeking a highly motivated scientist who will contribute significantly to the advancement and validation of our automated processes. This role primarily involves hands‑on laboratory work, where you will directly contribute to improving the efficiency, accuracy, and reliability of our robotic systems. This will provide you with a deep, intimate understanding of the intricacies of our technology. Beyond the lab, you will also serve as a key Multiply Labs representative during system deployments at customer sites.

This will involve working directly with clients to ensure seamless integration and optimal performance of our robotic solutions, offering an exciting opportunity to apply your expertise in real‑world settings and to contribute directly to customer success.
