Staff Electrical Engineer, Power Electronics, Optimus

Tesla’s Optimus humanoid electronics team is looking for highly motivated, skilled, and experienced electrical engineer to develop robots’ electrical “cardiovascular, sensory, and nervous” systems. This position is critical to the development of high-performance electromechanical actuation systems. You will join the team of electrical and mechanical design engineers to develop the most efficient, torque, and power dense actuation systems in the world. 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 responsible for power conversion across the entire robot, provide networking back bone, and accurately process sensory data 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 (modeling, schematic, layout, industrialization, bring up, and validation) of Optimus joint controllers. You will drive architectural design decisions and support industrialization and production activities. You will work closely with firmware, controls, and mechanical engineers.

Responsibilities

Own compete start-to-finish hardware development process: architecture development, requirement definition and specification, design execution, simulation, schematic, board layout, manufacturing and DFM iterations, board bring up and integration, and validation of circuit functionality Lead and organize collaboration 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

Expert-level 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) Expert-level understanding of analog and digital circuits (op-amps, microcontrollers, SPI, I2C, CAN, Ethernet, component selection, power dissipation, etc.) Strong experience in PCB layout for reduced parasitic inductance/capacitance, mixed power and signal board layout, design for EMI/EMC performance Strong experience with lab equipment (oscilloscopes, electronic loads, impedance analyzers, signal generators, LCR meters, etc.) Modeling and simulation experience (LTSpice, PLECS, ANSYS-Maxwell is preferred) Demonstrated experience shipping high-volume PCBAs Ability and willingness to tackle and rapidly iterate on open-ended challenges using first-principles approach Experience managing direct reports or leading a small team is preferred Degree in Electrical Engineering or related field, 5+ years of professional experience or equivalent experience
