Electrical Engineer, Power Electronics, Optimus

Tesla’s Optimus humanoid robot electronics team is looking for an electrical engineer to develop robots’ electrical “cardiovascular, sensory, and nervous” systems. Optimus hardware team joins electrical, mechanical, robotics, sensing, geartrain, electromagnetic, and manufacturing engineering disciplines in a highly collaborative, fast-paced development environment. Optimus electronics team designs and deploys circuits that control power conversion across hundreds of devices across all electrical systems of the robot (actuators, motors, sensors, battery, etc.). As part of the design team, you will be responsible for all aspects of electrical design (schematic, layout, industrialization, bring up, and validation) of Optimus joint controllers, work closely with firmware, motor controls, and mechanical engineers. You will also support industrialization and production activities.

Responsibilities

Own compete start-to-finish development: requirement definition and specification, design execution, simulation, schematic, board layout, manufacturing and DFM iteration, board bring up and integration, and validation of circuit functionality Collaborate with firmware, mechanical hardware, robot and motor controls, PCB layout, program management, and validation teams on the design of world leading robotic electrical hardware Debug various hardware interactions in a fast-paced multi-disciplinary environment Thoroughly document design requirements, calculations, validation results, etc. Rapidly iterate as design requirements and product features mature over time

Requirements

Strong understanding of power conversion/electronic circuit topologies and design (dc/ac inverters, dc/dc converters, battery powered circuit, Si/GaN/SiC FETs, diodes, gate drivers, semiconductor switching/conduction loss modeling and calculation) Strong understanding of analog and digital circuits (op-amps, microcontrollers, SPI, I2C, CAN, Ethernet, component selection, power dissipation, etc.) Experience in PCB layout for reduced parasitic inductance/capacitance, mixed power and signal board layout,design for EMI/EMC performance Circuit board design (Altium preferred) Proficiency with lab equipment (oscilloscopes, electronic loads, impedance analyzers, signal generators, LCR meters, etc.) Experience shipping high-volume PCBAs is preferred Modeling and simulation experience (LTSpice, PLECS, ANSYS-Maxwell is preferred) Basic scripting/programming ability (MATLAB/Python preferred) Basic knowledge of control theory of power converters, embedded programming, PWM Bachelors, Masters, PhD Degree in Electrical Engineering or related field, or equivalent experience
