Mechanical Engineering Co-op​/Intern

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

Today, these therapies are produced through manual, labor‑intensive processes. Costs are extremely high—often $500K–$2M per patient—limiting access to only a small fraction of those who need them.

As product complexity increases and the cost of failure and scientific labor rises, the industry is shifting toward automation. Robotics and AI are making automated biologics manufacturing feasible, reliable, and economically scalable.

We believe the future of biomanufacturing is robotic—closed, automated, and scalable—ensuring critical therapeutics are accessible to every patient who needs them.

We don’t just build robots—we’re building the essential infrastructure for next‑generation biologics. Our technology enables biopharma companies to scale production without redesigning their science, reducing regulatory hurdles and lowering costs so these treatments can reach more 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, dexterous 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.

We are looking for a Mechanical Engineering Co‑op/Intern to join our team in San Francisco for a full‑time co‑op/internship position starting in January 2027. You will apply your engineering skills to design robotic cartridges and consumables involved in the manufacturing of novel pharmaceutical products.

You’ll work directly with a cross‑functional hardware and software team on designing and building the current and next generations of Multiply Labs’ robotic consumables. The work spans selecting and designing consumables, setting high‑level design goals, building prototypes, and taking designs to production.

You’ll succeed in this role if you can optimize designs using first‑principles engineering approaches. We run several projects at once, so you’ll need strong documentation skills and the ability to turn ideas into action. You’ll help drive decisions on major projects while coordinating with colleagues.

• Own consumable and robotic design projects
• Investigate applicable technologies and components
• Prototype, test, and iterate on designs
• Create supporting design documentation, including 3D CAD models and detailed drawings

• Currently working towards a Bachelor of Science in Mechanical Engineering or a related field
• Strong mechanical fundamentals, creative problem‑solving, attention to detail, and communication skills
• Ability to solve complex technical problems by breaking them down into simpler pieces and executable tasks
• Experience with 3D CAD software (Onshape, Solid Works, etc.), including modeling and creation of detailed drawings
• Knowledge of mechanical components, common engineering metals, plastics, joining methods, part fabrication methods, and finishing operations
• Understanding of design for manufacturing and assembly (DFM/DFA) principles
• Highly motivated, independent, curious, and eager to learn

Additional preferred qualifications:

• Experience iterating through design cycles from concept through production, including concept generation, downselection, rapid prototyping, testing, analysis, and…
