Staff Power Electronics Engineer eVTOL

About the Role:We are seeking a highly motivated and experienced Senior Electrical Engineer to join our team in Los Angeles. In this role, you will be at the forefront of conceptualizing and developing new products through the design of circuits and complex systems. You will be responsible for the design and implementation of power converters, as well as the integration of these components into larger systems. Responsibilities:•Conceptualization and analysis of high power systems (>100 kW, AC-DC) to guide architecture and modularity of the system design.•Comparison and selection of converter topologies to meet system-level design requirements, including input power quality, output current ripple, and efficiency.•Design of power electronic converters, both AC-DC and DC-DC up to 50kW for integration into larger power systems.•Protection circuit design for current, voltage, and temperature.•Modeling and simulation of power circuits.•Selection of all circuit components.•Define converter control concept and complete small signal design and analysis.•Power loss analysis.•Thermal design and analysis of the power components.•Power quality design for 3-phase AC input (Power factor and total harmonic distortion).•Oversee procurement and assembly of hardware.•Lab bring-up and verification of initial design and revisions.•Support of the system integration and testing.•Work independently and exercise judgment in making design changes.Qualifications and Skills:•Bachelor's Degree in Electrical Engineering. A Master's degree in Electrical Engineering is a plus.•Extensive industry experience bringing power circuit designsproducts from concept to field deployment.•Knowledge of power conversion circuits and topologies:â—¦AC-DC: Totem pole PFC and 3 phase PFC, LLCâ—¦DC-DC: Buck, Full bridge, and LLCDCAC•Knowledge and experience with LTspice, PLECS and Matlab Simulink.•Knowledge and experience with schematic capture tools, with preference for Altium.•Knowledge and experience with printed circuit board design using popular CAD packages, with a preference for Altium.•Knowledge and experience mitigating EMI through circuit design and PCB layout.•Knowledge of Matlab, Python, MathCAD andor other common tools for design calculations.•Hands-on experience using lab equipment including soldering stations, oscilloscopes, power supplies, loads, network analyzers, data acquisition systems, and spectrum analyzers.•Strong and effective verbal, written, and interpersonal communication skills.•Experience designing high frequency magnetics is highly desirable.•Experience selecting (and designing with) microcontrollers is highly desirable.•Familiarity with Power QualityEMIEMCSafety Regulatory Compliance is desirable.•Firmware development for embedded controllers is desirable.
