Mechanical Design Engineer, Hands

About the Role:

Human-like dexterity is one of the final frontiers in robotics. As a Mechanical Engineer on our Hands team, you will be responsible for designing, prototyping, and scaling the mechanical architecture of our dexterous hands and fingers. You will work at the intersection of high-precision mechanics, tactile sensing, and advanced manufacturing to build reliable, high-durability hardware that interacts directly with the physical world.

Responsibilities

• Design and development of mechanical components and assemblies for dexterous hands — fingers, linkages, transmissions, and palm structures

• Own designs from concept through production: parts that satisfy load conditions, durability, form factor, and packaging constraints in an extremely space-constrained envelope

• Rapidly build, test, and break prototypes to validate assembly, range of motion, grasp performance, and wire routing. You'll use 3D printing, CNC machining, and manual fabrication

• Integrate tactile sensors, actuators, motors, and wire harnesses into compact fingertip and palm geometries, working closely with the tactile sensing and actuation teams

• Generate accurate 2D drawings using GD&T (ASME Y14.5) and drive parts through supplier selection, first article inspection, and production ramp

• Develop specifications and accelerated life test plans (grasp cycles, impact, wear) to validate the hand for its lifetime

• Perform basic analyses (tolerance, structural, thermal) to validate design decisions

• Collaborate with cross-functional teams (electrical, firmware, controls, industrial design) to consolidate requirements and integrate the hand into the full robot system

Qualifications

• Exceptional mechanical intuition. You understand how forces, materials, and mechanisms behave instinctively — especially small, high-cycle mechanisms

• 3+ years of experience (or equivalent "hard tech" projects) building complex, miniaturized electromechanical systems — robotic hands, grippers, surgical robotics, prosthetics, precision mechanisms, or consumer wearables

• High proficiency in SolidWorks, Catia, or similar tools; comfortable designing complex geometry in tight packaging

• Experience with electromechanical integration — sensors, small motors, flex circuits, and wire harnesses in constrained volumes

• Hands-on problem-solving approach with the ability to iterate quickly

• Experience designing for volume processes (MIM, injection molding, micro-machining, CNC) and working with contract manufacturers

• You are comfortable with ambiguity, move fast, and have an "engineering curiosity" that drives you to understand how the entire hand-arm system works, not just your part
