Mechanical Engineering Co-op/Intern (Spring 2027)
About the company
Come build the world’s best robots—and help make life-saving therapies accessible to all.
Your tasks
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.
- 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
Requirements
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.
- 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, SolidWorks, 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 manufacturing
- Hands-on experience with machine shop and prototyping tools
What we offer
- Competitive Compensation: $5,000/month.
- Real Ownership: Own meaningful design projects on robots that go into production, not side tasks.
- Mentorship: Work side by side with experienced mechanical, robotics, and software engineers.
- Office Perks: An energetic SF office culture featuring catered team lunches, stocked kitchen, and frequent team events.
- Great people, meaningful work, and a team that genuinely believes in what we’re building.
- No Set Hours: Set your own schedule in alignment with your manager and team. We hold a high bar, measuring success by impact and outcomes—not hours logged.

Physical & Working Conditions
- Ability to reach, stoop, crouch, and kneel, including entering and working inside a robotic cluster for maintenance, cleaning, or intervention
- Ability to lift up to 25 lbs (equipment, parts, tools) and up to 5 lbs overhead
- Manual dexterity to use hand tools, manage cabling, and perform mechanical adjustments
- Work primarily in a manufacturing area adjacent to a lab; must follow strict safety protocols (e.g., BSL-2) and maintain situational awareness
- Potential exposure to hazardous materials, including biological agents and cryogenics, while servicing equipment
- Required use of PPE (lab coat, safety glasses, gloves) for extended periods
- Flexible schedule, with occasional evenings or weekends for time-sensitive builds or testing
