About the Job

Requirements

  • Experience building power electronics systems, ideally from an original equipment manufacturer or semiconductor applications background.
  • Experience with power electronics systems focused on AC-DC and DC-DC power-conversion topologies and architecture, using silicon carbide, gallium nitride, and silicon MOSFETs.
  • Background in electrical and thermal modeling, simulations, and bench testing.
  • Experience leading cross-functional engineering teams.
  • Hands-on system architecture experience with high-voltage power electronics products in automotive safety-critical or industrial applications.
  • Experience collaborating with Tier 1 original equipment manufacturers on power-electronics development and integration, including system-level requirements, component selection, and cross-functional coordination.
  • Expertise using MOSFETs, SiC, GaN power ICs, AC-DC and DC-DC power-conversion topologies, motor control, and magnetics.
  • Experience working with functional safety teams to support compliance with ISO 26262, UL safety, and other automotive or industrial safety standards; functional safety experience is desirable but not mandatory.
  • A Master’s or Ph.D. in Electrical Engineering, Systems Engineering, or a related field, with at least 10 years of experience in power electronics for automotive systems, AI data centers, or related applications.
  • Understanding of solid-state switching technologies such as SiC and GaN and their applications in high-reliability automotive and industrial environments.
  • Experience architecting systems to meet ISO 26262 functional-safety requirements, including safety concepts, technical safety requirements, and safety cases.
  • Familiarity with automotive communication protocols such as CAN, LIN, and Ethernet, and with system-integration challenges.
  • Familiarity with different motors, motor-control algorithms, and position control.
  • Ability to make architectural decisions in ambiguous or evolving technical environments.
  • Experience representing technical strategy in customer engagements, industry working groups, or standardization bodies is a plus.

Responsibilities

  • Lead system-architecture definition for next-generation power-electronics solutions, aligning with functional-safety, performance, and scalability requirements.
  • Collaborate with original equipment manufacturers and internal product, design, systems, software, and validation teams to define and refine system-level requirements and interfaces.
  • Drive architectural decisions from concept through production, balancing power, sense and control, thermal, cost, mechanical, and safety constraints.
  • 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 architecture-modeling, safety-analysis, and system-validation practices.
  • 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.
  • Command of EMI/EMC, radiation tolerance, and space applications.
  • Experience with functional safety is desirable but not mandatory.
  • Strong analytical and problem-solving skills.
  • Ability to communicate technical concepts to customers, discover customer needs, and translate complex concepts into customer-ready specifications.
  • Ability to influence internal teams and external partners at all levels.
