Mechanical Engineer Intern

About the team

Droyd builds autonomous robotic systems that automate repetitive manual work in real environments. Our robots operate in production settings, which means mechanical design must be practical, manufacturable, and tightly integrated with electronics and actuation.

Our mechanical team designs and builds the physical systems that make our robots work. This team spends as much time prototyping and testing as it does designing.

About the role

As a Mechanical Engineering Intern at Droyd, you’ll work hands-on on real robotic hardware. You’ll help design, build, and iterate on mechanical subsystems that ship to production robots.

This is not a CAD-only role. You’ll be expected to prototype, test, and refine designs alongside full-time engineers.

This role is based in Burlingame, CA. We’re an in-person company. We build faster that way.

In this role, you’ll

• Support mechanical subsystem design from concept through prototype and iteration

• Create and modify CAD models for parts and assemblies

• Help perform basic load calculations, testing, and analysis

• Design parts for rapid prototyping methods such as 3D printing and CNC machining

• Build and assemble prototypes using 3D printers, hand tools, and shop equipment

• Help integrate mechanical designs with motors, sensors, and basic mechatronic components

• Document designs, tests, and learnings

We’re looking for candidates who

• Are current juniors or seniors (or equivalent) studying mechanical engineering or a related field

• Have hands-on experience from clubs, personal projects, or coursework involving physical hardware

• Can show examples of projects taken from concept to a physical build

• Are comfortable using modern CAD tools (Onshape preferred, but not required)

• Are willing to balance school and work in a fast-paced, build-heavy environment

• Take ownership, learn quickly, and enjoy working with real hardware

Nice to have

• Experience with FEA, topology optimization, or generative design

• Exposure to machining, tolerancing, or manufacturing workflows

• Familiarity with electronics, motors, or control systems

• Interest in industrial or visual design

About Droyd

Droyd builds autonomous robotic systems to automate manual work for enterprises. We design the hardware, write the control stack, and deploy robots that operate in real environments.

If we do this right, robots stop being prototypes and start being infrastructure.

Join us and help build hardware that ships.
