Sr. Electrical Engineer, Optimus Charging

What to Expect

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.

What You’ll Do

• 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

What You’ll Bring

• 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
