Senior Mechanical Engineer- Neck

Own the mechanical architecture of the neck — kinematics, joint arrangement, structural design, and packaging of the full mechanism within a slender, ID-constrained envelope

Lead actuation selection and packaging for the neck's degrees of freedom — evaluating motor, gearbox, and transmission options against torque, bandwidth, backdrivability, acoustic, and packaging requirements

Define the head mass and center-of-gravity budget in partnership with the head team, and own the system-level trade between head mass, neck actuator sizing, and dynamic performance

Develop and validate the head stabilization strategy in collaboration with controls engineers — structural stiffness, backlash and compliance management, vibration isolation, and the dynamic performance needed for stable imagery from head-mounted cameras

Design for quiet, smooth, lifelike motion — managing gear noise, cogging, and structural resonances in a subsystem that operates close to people's faces

Define and own the mechanical interface to the head — structural mount, alignment and registration, electrical pass-through, and serviceability — and the interface to the torso below, driving both to closure with their respective teams

Own cable routing through the neck: power and data runs to the head across moving joints, service loops, strain relief, and bend-cycle durability through the full range of motion

Work closely with the cladding team on the moving-surface problem — gaps, pinch points, flexible or telescoping cladding elements, and attachment schemes that survive continuous articulation

Create and maintain CAD models, drawings, tolerance stacks, and BOMs to support design reviews, prototyping, and manufacturing handoffs

Plan and execute prototype builds and test campaigns — dynamic performance, acoustics, durability, and stabilization — and lead root cause analysis when issues arise
