Sr. Power Electronics Engineer
About The Position
Design and develop electrical circuits and power converters for Rivian’s off-board charging products, including the Rivian Adventure Network DC fast charger, Level-2 AC charger, and energy products. The position is based in Torrance, California, and reports to the Sr. Manager, Power Electronics. The Senior Power Electronics Engineer leads development of high-power electrical circuits and performs circuit analysis, component and magnetic design, simulation, prototyping, and testing. The role works with suppliers and cross-functional teams spanning Mechanical, Software and Controls, Systems, Test, Quality, Reliability, and Manufacturing.
Requirements
- M.S. in Electrical Engineering and at least 5 years of relevant industry experience, or a Ph.D. and at least 1 year of industry experience, specializing in power electronics.
- Familiarity with common single- and three-phase topologies, including AC-DC PFC rectifiers and isolated DC-DC converters such as dual active bridge and LLC converters.
- Solid understanding of power semiconductor switches and diodes and their characteristics.
- Strong experience designing and optimizing power converter circuits, including gate drivers.
- Familiarity with digital control of power electronic circuits, including power-stage average/small-signal modeling, closed-loop control, and PWM modulation.
- Experience with bidirectional AC/DC or DC/DC power conversion.
- Experience using software tools such as Spice, PLECS, Ansys, and MATLAB.
- Experience with PCB layout using Altium Designer.
- Exposure to EMC requirements and safety certification.
- Ability to work in a fast-paced development environment.
Nice To Haves
- Expertise in high-power EV chargers or stationary energy-storage-related power converters is preferred.
- Experience in magnetic design and circuit parasitic analysis using FEA tools such as Ansys Maxwell/Q3D or equivalent is a plus and strongly preferred.
Responsibilities
- Lead development of high-power electrical circuits, including active power-factor-correction AC-DC rectifiers, isolated DC-DC converters, filter boards, and embedded controllers.
- Perform stress analysis, component selection, magnetic design, schematic creation, circuit design, and PCBA layout.
- Conduct trade studies on key decisions such as circuit topology, power devices, and magnetics.
- Simulate power converters and basic converter control algorithms using MATLAB/Simulink, PLECS, LTSpice, and other tools.
- Analyze structures and magnetic components, including bus bars and high-frequency transformers and inductors.
- Design EMI/EMC filters.
- Interact with suppliers on critical components.
- Test prototype power electronics circuits in the lab.
- Characterize silicon, SiC, and GaN power semiconductor devices.
- Collaborate with Mechanical, Software and Controls, Systems, Test, Quality, Reliability, and Manufacturing teams.
