Job Description

Position Overview

The Engineer II – Power Electronics Hardware is responsible for supporting the design, development, and sourcing of electronic hardware for advanced powertrain modules, including Inverters, Powertrain Control Modules, Battery Management Modules, and both DC-DC and AC-DC Converters.

Key Responsibilities:

  • Develop specification/requirement for developing power stage, control board and gate driver board of different modules, switches 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.
  • Excellent oral and written communication skills.
  • Strong suppliers interface skills.
  • 2+ years of professional experience in high-voltage power electronics design, development, and testing – focused on DC/AC inverters, DC-DC converters, on-board chargers, power supply, and power distribution systems (automotive experience preferred).
  • Understanding of global industry standards (IEC, ISO) and trends to provide the latest technology solutions.
  • Experience working with 12V, 400V, >800V voltage levels and component selections.
  • Hands on experience in power electronics hardware development including design, debugging and validation of: Semiconductor switching waveforms, loss modeling and thermal management.
  • Experience in PCBA circuit design and layout for optimal placement strategies for better manufacturability, power/signal routing and EMC optimization.
  • Experience in PCB bring-up, bench-test & determine root cause for issues identified.
  • 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.
  • 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.
  • Experience in microprocessors, such as Infineon tri-core family, NxP MCUs.
  • Experience in data logging with Vector CAN tools.
  • Experience in automation testing equipment.
  • Knowledge of Functional safety ISO26262.
  • Basic knowledge of Quality Management Systems (ISO 9001:2015) and Environmental Management Systems (ISO 14001:2015), as applicable.

Benefits & Perks:

  • Medical Plan choices include HMO, PPO & HDHP (High Deductible Health Plan).
  • Dental & Vision Plans.
  • Health Savings Account & Flexible Spending Account.
