Job Description
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 has to be robust, manufacturable, and tightly integrated with electronics and control systems.
Our mechanical team designs the structures, linkages, and assemblies that make the robots real. This work moves fast and lives on the shop floor as much as it does in CAD.
About the role
As a Mechanical Design Engineer at Droyd, you’ll own mechanical subsystems from first sketch through working prototype. You’ll design, build, break, and iterate on real hardware.
This is a hands-on role. You’ll spend time in CAD, but also at the printer, in the shop, and on the robot. You’ll work closely with electrical, software, and robotics teams to bring systems together.
This role is based in Burlingame, CA. We’re an in-person company. We build faster that way.
In this role, you’ll
Own mechanical subsystem design from concept to prototype and iteration
Design parts and assemblies in CAD, supported by hand calculations and FEA when needed
Design for rapid prototyping methods including 3D printing and CNC machining
Make decisions on materials, tolerances, and manufacturing methods
Integrate mechanical designs with motors, sensors, electronics, and actuators
Build prototypes yourself using 3D printers, shop tools, and CNC equipment
Work closely with manufacturing to turn designs into physical hardware quickly
We’re looking for someone who
Has a strong portfolio showing complete systems taken from concept to physical prototype
Has experience on hands-on engineering teams such as Formula SAE, aerospace clubs, or robotics teams
Has internship or early-career experience on real hardware projects or at hardware startups
Is proficient with modern CAD tools (Onshape preferred, but not required)
Understands manufacturing methods, tolerancing, and assembly workflows
Is comfortable with hands-on fabrication and rapid iteration
Nice to have
Experience with FEA, topology optimization, or generative design
Exposure to electronics, controls, or mechatronic systems
Interest in industrial or visual design alongside functional engineering
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.
