Full Job Description
The Role
As a Senior Mechanical Engineer, you will own mechanical subsystems of our robots end to end, from concept through production, including actuator selection and structure to drivetrain, linkages, and field-ready assembly. You make architecture and design tradeoffs, design it, machine it, assemble it, and fix it on robots running in live operations.
This is not a bench role. Your designs face real constraints: variable floors, tight corridors, elevator transitions, and duty cycles that push hardware hard.
What You'll Do
Own mechanical architecture and subsystem design from concept through production: drivetrain, structure, actuation, linkages, enclosures
Select and integrate motors, gearboxes, bearings, and actuators, making tradeoffs across performance, reliability, cost, and manufacturability
Run load, stress, and tolerance analysis to size parts and predict failure
Build prototypes in our in-house shop (mill, lathe, welding, 3D printing, laser cutting)
Design for manufacturing, assembly, serviceability, and field reliability, working closely with vendors and manufacturers
Debug mechanical failures on deployed robots and drive fixes back into the design
Mentor junior engineers and manage vendors for machined, sheet metal, and molded parts
What You Bring
5+ years of relevant industry experience designing and shipping hardware
Strong mechanical fundamentals: material selection, GD&T, tolerance analysis, DFM
Track record owning actuated or mobile mechanisms from concept through production
CAD fluency in SolidWorks, Fusion, or Onshape
Hands-on fabrication: you've run a mill and lathe, bent sheet metal, and welded
Experience making architecture and design tradeoffs, mentoring junior engineers, and working with manufacturers
A track record of hardware you've shipped and a portfolio of things you've built on your own time
Bias toward action: prototype fast, test early, fix what breaks
Values
Pace of learning trumps everything.
Relentless refinement of our craft.
Low ego, high ownership.
All-in on the mission. We work in person, and this isn't a 9-to-5.
