About The Position

We are seeking a talented and experienced Senior Mechanical Engineer to join our
team. You will play a pivotal role in designing, prototyping, testing, and
scaling the mechanical systems for our robotic systems. This role requires a
strong background in mechanism design and mechatronics, coupled with the ability
to bring products from concept to production.

Fauna Robotics, an Amazon company, is building capable, safe, and genuinely
delightful robots for everyday life. Our goal is simple: make robots people
actually want to live and interact with in everyday human spaces.
We believe that future won’t arrive until building for robotics becomes far more
accessible. Today, too much effort is spent reinventing the fundamentals. We’re
changing that by developing tightly integrated hardware and software systems
that make it faster, safer, and more intuitive to create real-world robotic
products.
Our work spans the full stack: mechanical design, control systems, dynamic
modeling, and intelligent software. The focus is not just functionality, but
experience. We’re building robots that feel responsive, expressive, and
genuinely useful.
At Fauna, you’ll work at the frontier of this space, helping define how robots
move, manipulate, and interact with people in natural environments. It’s an
opportunity to solve hard problems across hardware and software with a team
focused on making robotics accessible and joyful to build.
If you care about making robotics real for everyone and building systems that
are as delightful as they are capable, we’re interested in hearing from you.
