4+ years of experience building physical robots, including at least one shipped product.
Proficient in CAD software (SolidWorks, Onshape, Fusion, or equivalent).
Hands-on skills in electromechanical systems: harnesses, soldering, motors, sensors, and scopes.
Strong understanding of control fundamentals: kinematics, PID control, and calibration on real hardware.
Experience with ROS/ROS 2 for integrating arms and sensors with software stacks.
Familiarity with firmware and low-level interfaces (CAN, EtherCAT, serial).
Practical Python skills and comfort with Linux; ability to read and modify C++.
Responsibilities
Design and fabricate custom parts such as brackets, mounts, and tooling.
Assemble and integrate components like arms, bases, and sensors into complete robots.
Incorporate new hardware into the software stack using vendor SDKs and ROS 2.
Develop and tune manipulation control for tasks like trajectory following and grasping.
Calibrate arms and sensors, optimizing controllers for performance.
Iterate on mechanical design and control behavior based on testing results.
Build wiring harnesses and manage power distribution for robots.
Conduct final testing of robots before shipment and document the build process.
Benefits
Opportunity to work hands-on with physical robots daily.
Collaborative environment with a focus on hardware integration and control.
Potential for travel to customer sites for deployment and testing.
Engagement in innovative projects that aim to reshape manual work with robotics.
Encouragement to showcase personal projects through photos, CAD, or videos.
Full Job Description
Job Description Overview
We're hiring a Robotics Mechatronics Engineer to help develop our robot fleet. You'll design, fabricate, and assemble warehouse robots, then integrate them with our software stack and tune the manipulation control that makes them work. This is a mechanically led role spanning physical design and assembly, hardware integration, and controls software. We're looking for people who have shipped real robot hardware before.
What you'll do
Design and fabricate custom parts: brackets, mounts, end-of-arm tooling, and cable management.
Assemble and integrate purchased arms, bases, grippers, and sensors into complete robots.
Bring new hardware into our software stack through vendor SDKs, firmware, and ROS 2.
Develop and tune manipulation control: trajectory following, grasping, and force and compliance behavior.
Calibrate arms and sensors, and tune controllers for repeatability, speed, and payload.
Iterate on both the mechanical design and the control behavior based on results from the floor.
Build wiring harnesses and power distribution.
Test robots before they ship, and document how they were built.
What you bring
4+ years building physical robots, including at least one you shipped.
Strong CAD (SolidWorks, Onshape, Fusion, or equivalent).
Hands-on electromechanical skills: harnesses, soldering, motors, sensors, and scopes.
Solid controls fundamentals: kinematics, PID and trajectory control, and calibration on real hardware.
Experience integrating arms and sensors with a software stack through ROS/ROS 2 and vendor SDKs.
Firmware and low-level interface experience (CAN, EtherCAT, serial).
Practical Python and comfort working in Linux; able to read and modify C++.
Bonus: mobile manipulators, warehouse automation, cobots, force control, or end-of-arm tooling.
Additional Notes
You'll own hardware integration and manipulation control. Our software team owns autonomy, teleoperation, and the real-time stack.
Our team develops on physical robots in person, so expect to be on the floor with hardware most days.
Need to be located or willing to relocate to San Francisco, CA
Travel to customer warehouse sites for deployment and testing
Physical work required: lifting robot components, warehouse environments, hand and power tools
Please include photos, CAD, or video of a robot you built. This matters more than your resume.
Come join us in building a new global economy, where anyone can do manual work remotely and with robo-scale. Together, we can make goods and resources more affordable and available than they've ever been, for everyone on Earth.
