Job Description
Position Overview
The Sr. Engineer II – Power Electronics Hardware is responsible for electronic hardware design to support in-house development of advanced Powertrain modules. Examples of such modules are Inverters, Powertrain Control Module, Battery Management Module, DC-DC and AC-DC Converters.
Key Responsibilities
- Develop specification/requirement for developing power stage, control board and gate driver board of different modules through cascading the requirement from the design specification.
- Decompose system level requirements to drive component level design requirements.
- This role can include bespoke designs, upgrade of existing designs, and applications engineering.
- Support Powertrain team from specification to design, prototype, and investigation on manufacturing for quality issues and development of a high-performance powertrain.
- Select components for the design and work with suppliers to develop advanced components.
- Optimize designs for system performance, quality, DFM/DFA and cost.
- Lead and participate in Design Reviews.
- Test and debug electrical hardware at circuit board and assembled product level.
- Develop automation testing setup for module level validation.
- Support SW (BSW & ASW) engineers for hardware‐software integration work.
- Other duties, as assigned.
Required Qualifications
- Master’s degree in Electrical Engineering (PhD preferred)
- Excellent oral and written communication skills
- 5+ years of directly related Electrical Engineering experience required (Automotive experience preferred)
- Understanding of global industry standards (IEC, ISO) and trends to provide the latest technology solutions
- Experience in PCBA layout for optimal placement strategies for better manufacturability, power/signal routing and EMC optimization
- Experience in HV Power Electronics engineering and thermal management, such as 400V, and >800V voltage levels and component selections
- Experience in IGBT, Si/SiC, and GaN MOSFET WBG technology and working knowledge with IGBT and MOSFET, gate driver circuit design
- Design power and control circuit components including LV power supply, EMI filters, magnetics, semiconductors, gate drives, sensing, protection circuitry and control logic
- Knowledge of Functional safety ISO26262
- Hands-on hardware experience and strong understanding of power converter (AC/DC, DC/DC & DC/AC) and OBC design
- Familiar with schematic capture and power converter circuit simulation tools such as Altium/MATLAB/PSIM/PSpice/MathCad. Perform Circuit Simulation, WCA analysis.
- Experience in embedded software development with TI/Freescale/TriCore/DSP 32-bit processors or FPGA;
- Experience in microprocessors, such as Infineon tri-core family, NxP MCUs
- Experience in data logging with Vector CAN tools
- Experience in automation testing equipment with LabView
- Basic knowledge of Quality Management Systems (ISO 9001:2015) and Environmental Management Systems (ISO 14001:2015), as applicable
