Mechanical Engineer Intern

Thought processThought processAbout the TeamDroyd builds autonomous robotic systems that automate repetitive manual work in real environments. We design and manufacture our hardware in-house, which means iteration, fabrication, and execution all happen under one roof.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 RoleAs a Mechanical Engineering Intern at Droyd, you will work hands-on on real robotic hardware. You will help design, build, and iterate on mechanical subsystems that ship to production robots.This is not a CAD-only role. You will be expected to prototype, test, and refine designs alongside full-time engineers.This role is based on-site in San Francisco, CA.In This Role, You'llDesign & AnalysisSupport mechanical subsystem design from concept through prototype and iterationCreate and modify CAD models for parts and assembliesHelp perform basic load calculations, testing, and analysisDesign parts for rapid prototyping methods such as 3D printing and CNC machiningPrototyping & Build Build and assemble prototypes using 3D printers, hand tools, and shop equipmentHelp integrate mechanical designs with motors, sensors, and basic mechatronic componentsIterate quickly based on test results and engineering feedbackDocumentation & Collaboration Document designs, tests, and learningsWork alongside full-time engineers across mechanical, electrical, and softwareCommunicate progress, blockers, and findings clearlyWork Environment & Schedule On-site in San Francisco, CAPart-time or full-time internship, balanced with school commitmentsWe're Looking For Candidates WhoAre current juniors or seniors (or equivalent) studying mechanical engineering or a related fieldHave hands-on experience from clubs, personal projects, or coursework involving physical hardwareCan show examples of projects taken from concept to a physical buildAre comfortable using modern CAD tools (Onshape preferred, but not required)Are willing to balance school and work in a fast-paced, build-heavy environmentTake ownership, learn quickly, and enjoy working with real hardware Nice to have: Experience with FEA, topology optimization, or generative designExposure to machining, tolerancing, or manufacturing workflowsFamiliarity with electronics, motors, or control systemsInterest in industrial or visual design About Droyd Droyd builds autonomous robotic systems that operate in real production environments. We design the hardware, develop the control stack, and generate the data that enables generalist robotics. If we do this right, robots stop being demos and start being infrastructure. Join us and help build the systems that make it real.
