Sr. Electronics Engineer, Actuators & Drives, Frontier AI & Robotics

Join Amazons Frontier AI & Robotics team and take ownership of the electronics that make our robots move. As a Sr./Staff Electronics Engineer Actuators & Drives you will conceptualize design and test the motor drive electronics that power our in-house robotic actuatorsfrom the gate drivers and power stages that command motor current to the sensing circuits and communication interfaces that give our robots proprioceptive awareness. Your printed circuit board (PCB) designs will live inside each of our next-generation robotic systems directly enabling the embodied intelligence that is central to FARs mission.

Key job responsibilities
Conceptualize design and validate motor drive electronics for in-house robotic actuators including inverter power stages gate driver circuits current and position sensing and power management subsystems from concept through prototype and production
Lead PCB-level design of compact high-power-density motor drive boards including schematic capture component selection and collaboration with PCB layout engineers to achieve signal integrity thermal and EMC requirements in constrained actuator form factors
Characterize and optimize inverter switching performance efficiency and thermal behavior across the full operating envelope of FARs actuator variants using bench measurements and simulation to guide design decisions
Define and implement current sensing architectures (shunt-based Hall-effect or integrated IC-based) and position/velocity sensing interfaces (encoder resolver Hall sensor) to support high-bandwidth FOC firmware on microcontrollers and DSPs
Partner with firmware engineers to define hardware-software interfaces for motor drive control loops fault detection logic and communication protocols (CAN EtherCAT SPI) ensuring electronics designs support the real-time control requirements of robotic actuation
Collaborate with motor design and mechanical engineers to specify the electrical characteristics of custom BLDC and PMSM motors align inverter design to motor parameters and validate the integrated actuator electro-mechanical system
Lead hardware bring-up functional testing and failure analysis for new actuator electronics prototypes developing test plans and characterization setups that systematically validate design performance and identify failure modes
Define electronics design standards review processes and design-for-manufacturability (DFM) guidelines for FARs actuator drive portfolio and mentor junior engineers in motor drive electronics design best practices


A day in the life
Your day centers on the full electronics development cycle for our custom actuator drive systems. You might start by reviewing simulation results for a new inverter topology then transition to the lab to characterize switching losses and thermal performance on a prototype motor drive board. Later in the day you could be collaborating with motor design engineers on back-EMF waveform analysis refining gate drive timing to optimize inverter efficiency or working with firmware engineers to define current sensing interfaces and hardware abstraction layers.
Across the week youll be involved in schematic capture and PCB layout reviews with your design team participating in design review gates and iterating on hardware based on test findings. Youll navigate the challenge of fitting high-performance drive electronics into compact thermally constrained actuator packagesdesigning for the power density reliability and robustness our robots demand. Your work will span from concept and architecture through silicon bring-up and youll play a key role in defining the electronics roadmap for FARs actuator portfolio.
