Sr. Electrical Engineer, Optimus Charging

Tesla's Power Electronics team is hiring a Sr. Electrical Engineer to work on the Optimus charger program. You will be part of the Power Electronics group — the same team that designs power conversion hardware across Tesla's automotive and energy products — and will apply that expertise to developing charger systems for Tesla's Optimus humanoid robot. This is a high-impact role where you will own the full hardware development lifecycle, from architecture through production, in a fast-paced environment where requirements evolve rapidly.

Responsibilities

Architect, design, build, and industrialize power converter hardware for Optimus charger systems, from specification through prototype, reliability validation, and production Own start-to-finish circuit development: architecture development, requirement definition, design execution, simulation, schematic capture, and board layout Develop and optimize advanced power electronics topologies for charger applications including AC/DC rectifiers, DC/DC converters, and battery charging circuits Perform circuit modeling, component selection, PCB layout, prototyping, and hardware validation Design PCB layouts optimized for reduced parasitic inductance and capacitance in high-power charging circuits Lead cross-functional collaboration with firmware, mechanical, robotics, controls, systems, manufacturing, and reliability teams Debug complex hardware interactions across electrical, firmware, and mechanical domains Document design requirements, calculations, simulation results, and validation data Iterate rapidly as charger and robot platform requirements evolve

Requirements

Degree in Electrical Engineering or equivalent experience 4+ years of hands-on power converter design and industrialization experience Strong understanding of power conversion topologies — both theory and practical design — including DC/AC inverters, DC/DC converters, and battery-powered circuits Experience with high voltage power semiconductor selection (IGBTs, Si/SiC/GaN MOSFET’s, and Diodes), design of gate drive and analog/digital sensing circuits Advanced analog and digital circuit design skills Experience in PCB layout for minimal stray inductance/capacitance, component placement strategies for better manufacturability, power/signal plane definition, and EMC optimization Proficiency with simulation tools such as LTSpice, PLECS, or ANSYS-Maxwell Proficiency with lab equipment including oscilloscopes, electronic loads, and power analyzers Familiarity with control theory and embedded programming for power electronics
