The RoleAs 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.
