About the Job

Requirements

  • The candidate should have extensive experience defining and architecting solid-state power device solutions for safety-critical systems and motor control.
  • The candidate should have an OEM or semiconductor applications background and years of experience building power electronics systems.
  • The candidate should have experience with power electronics systems focused on AC-DC and DC-DC power conversion topologies and architecture using SiC, GaN, and silicon MOSFETs.
  • The candidate should have a strong background in electrical and thermal modeling, simulations, and bench testing.
  • The candidate should have experience with system architecture of high-voltage power electronics products for automotive safety-critical or industrial applications.
  • The candidate should have experience collaborating with Tier 1 OEMs on development and integration of power electronics systems, including system-level requirements, component selection, and cross-functional coordination.
  • Preferred: A Master's or Ph.D. in Electrical Engineering, Systems Engineering, or a related field, with a minimum of 10 years of experience in power electronics for automotive systems, AI datacenters, or related applications.
  • Preferred: Deep understanding of solid-state switching technologies such as SiC and GaN and their application in high-reliability automotive and industrial environments.
  • Preferred: Experience architecting systems to meet ISO 26262 functional-safety requirements, including safety concepts, technical safety requirements, and safety cases.
  • Preferred: Familiarity with automotive communication protocols such as CAN, LIN, and Ethernet, and system-integration challenges.
  • Preferred: Familiarity with different motors, motor-control algorithms, and position control.
  • Preferred: Experience representing technical strategy in customer engagements, industry working groups, or standardization bodies is a plus.
  • Expertise in MOSFETs, SiC, GaN power ICs, AC-DC and DC-DC power conversion topologies, motor control, and magnetics is required.
  • Functional-safety experience is desirable but not mandatory.
  • Command of EMI/EMC, radiation tolerance, and space applications is desired.

Responsibilities

  • Lead system architecture definition for next-generation power electronics solutions, ensuring alignment with functional-safety, performance, and scalability requirements.
  • Collaborate with OEMs and internal cross-functional teams, including product, design, systems, software, and validation, to define and refine system-level requirements and interfaces.
  • Drive end-to-end architectural decisions from concept through production, balancing trade-offs across power, sense and control, thermal, cost, mechanical, and safety constraints.
  • Work with the functional-safety team to ensure compliance with ISO 26262, UL safety, and other relevant automotive or industrial safety standards.
  • Translate customer and market requirements into robust, modular, reusable system architectures that support long-term product roadmaps.
  • Provide technical leadership and mentorship to systems-engineering teams, guiding best practices in architecture modeling, safety analysis, and system validation.
  • Stay current with industry trends, emerging technologies, and regulatory changes, and integrate relevant innovations into architectural planning.

Desired Qualifications

  • Experience with SiC and GaN devices is preferred.
  • Strong analytical and problem-solving skills, including the ability to make architectural decisions in ambiguous or evolving technical environments.
  • Excellent communication and leadership skills, including the ability to influence internal teams and external partners at all levels.
