3Rd Shift Access Control Engineer Jobs (NOW HIRING)

We’re making the world a more walkable place. Through intuitive personal mobility, we make walking faster, more efficient, and more accessible to empower people to choose walking over sitting in traffic. By giving people the ability to Moonwalk, we believe the path forward to a better future is easily reached on your own two feet.

Our flagship product, Moonwalkers, are the world’s fastest robotic shoes, augmenting natural walking with intelligent locomotion assistance. By giving people the ability to Moonwalk, we believe the path toward a more human-scale future can be reached on your own two feet.

We are building the next generation of Moonwalkers and are looking for engineers who thrive in fast-paced environments where hardware, software, and human motion intersect.

We are covered in Wired, CNET, Gizomodo, PCMag and many other tech press.

The Gait Control Engineer will lead the development of locomotion control algorithms for Shift’s robotic footwear platform. This role focuses on designing, implementing, and deploying robust control and estimation algorithms that enable safe, intuitive, and responsive human-machine interaction.

You will work closely with mechanical, electrical, and firmware teams to develop algorithms that run reliably on embedded systems while handling real-world variability in human gait and terrain.

This role requires strong intuition for human locomotion, control systems, and embedded algorithm implementation.
