Every motion our robots make starts with an actuator, and we’re looking for an Actuator Systems Engineer to help us build better ones.
Every motion our robots make starts with an actuator, and we’re looking for an Actuator Systems Engineer to help us build better ones. This role is for someone who enjoys the full loop: building a model of how a motor or transmission should behave, rigorously testing this around other industry standards, and then iterating on the hardware or firmware until the desired specification is met.
You’ll work across electrical, mechanical, and firmware design, and you’ll own actuator performance from the bench all the way to robots running in people’s homes. The things you learn and build will directly shape how safe, reliable, efficient, quiet, and strong our robots are.
Plan and run characterization testing on our actuators, covering things like torque constant, friction, efficiency, thermal behavior, and wear over time, and turn those results into models and specs the rest of the team can rely on
Build and maintain electromechanical and thermal models of our actuators that help us predict robot performance, set safe operating limits, and support the controls and simulation teams
Contribute to the electrical design of the actuator, including motor selection, motor drivers, sensing, and protection, working closely with our EE team and suppliers
Contribute to the mechanical design of the actuator, including transmissions, bearings, housings, and thermal paths, with an eye toward torque density, efficiency, and manufacturability
Write and tune motor control firmware, including current and position control, current and thermal limiting, calibration, and fault detection
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.
Experience in developing functional specifications, design verification plans and functional test procedures
PhD in EE, ME, Robotics, Physics, or a related field, or a Master’s degree in one of these fields and 4+ years of industry experience developing actuators, motors, or other electromechanical systems
Experience building models of electromechanical or thermal systems and validating them against test data
Hands-on experience testing and characterizing motors or actuators
Experience writing embedded motor control firmware in C or C++, and analyzing data in Python
Experience leading a technical project from early concept through validation
Experience with brushless motor design, field-oriented control, or power electronics
Experience designing gear trains such as planetary, cycloidal, or harmonic drives
Experience with thermal modeling and with reliability or life testing
Experience taking an actuator design from prototype into production with suppliers
Publications or patents related to actuation, motor control, or electromechanical design
