Join the Future of Robotic Biomanufacturing!

Multiply Labs is a robotics company on a mission to solve a significant bottleneck in modern medicine: the manufacturing of life‑saving advanced biologics— including cell therapies, gene therapies, mRNA therapies, and more.

Currently, advanced biological therapies are produced through manual, labor‑intensive processes. This keeps costs astronomical—often exceeding $0.5M‑$2M per patient—and limits access to only a fraction of those in need.

As labor scarcity for scientists compounds against increased product complexity and sky‑high costs of failure, the emergence of robotics and AI makes automated manufacturing of biologics feasible, reliable, and economically scalable.

We envision that the biomanufacturing factory of the future is fully robotic—closed, automated, and scalable, making therapeutics for some of the most important indications for patients today widely accessible.

We don’t just build robots; we build the infrastructure for the next generation of biologics manufacturing. Our technology allows biopharma companies to scale production without redesigning their science, drastically lowering regulatory hurdles and bringing costs down to a level where these treatments can actually reach patients.

The Mission:
Build the world’s best robots to make life‑saving therapies accessible to all.

The Technology:
Advanced robotic orchestration, high‑precision automation, cloud‑integrated hardware‑software systems, dextrous manipulation, and imitation learning.

The

Location:

Headquartered in San Francisco, CA.

The Backing:
Supported by premier investors, including Casdin Capital, Lux Capital, and Y Combinator.

• As a Mechanical Engineer in the Multiply Labs team, you will apply your engineering expertise to design complex automated machinery involved in the manufacturing of novel pharmaceutical products.
• You’ll be working directly with a cross‑functional hardware and software team on designing and building the current and next generations of Multiply Labs’ robotic systems. This ranges across designing and selecting robotic equipment, determining high‑level design goals and objectives, building prototypes and taking them to production. You’ll succeed in the role if you can optimize design using first‑principle engineering approaches. We have a mix of projects running simultaneously.
  
  You will need great documentation skills and ability to organise thoughts and ideas into actions in order to drive decision‑making conversations on major projects while coordinating with colleagues.
