Relocation: Available assistance if needed, preference for local candidates

Overview
We are seeking a senior-level Principal Applications Engineer with deep expertise in low-voltage DC-DC converters (Buck conversion products) to support advanced power module products used in high-performance computing, networking, storage, and other demanding applications.
This role is highly technical and customer-facing, combining hands-on lab work, post-sales design-in support, and close collaboration with internal design, validation, and field engineering teams. The position is based in the San Jose / Milpitas area and supports a major local customer.
The ideal candidate is a former design engineer or verification engineer who has worked directly on DC-DC converter designs and enjoys solving complex technical problems in lab environments while working closely with customers.

Key Responsibilities
  • Act as the technical subject matter expert for DC-DC converter and buck conversion products.
  • Provide post-sales technical guidance and design-in support to customer engineering teams.
  • Conduct complex qualification and verification testing in local labs and at customer sites (approximately 50–75% onsite depending on project phase).
  • Support field engineers by resolving advanced technical questions and system-level issues.
  • Verify products against customer specifications and application requirements.
  • Collaborate closely with internal design engineering, validation, manufacturing, and business development teams to resolve issues and deliver results on schedule.
  • Translate customer technical needs into product recommendations, specifications, and development feedback.
  • Identify potential design or integration risks early and communicate clearly with both customers and internal teams.
  • Coordinate product integration efforts between component suppliers, internal teams, and customers.
  • Develop and deliver technical presentations and seminars for customers and field engineering teams.
  • Define initial project scope, prepare project plans, and maintain technical documentation.
  • May sit onsite with customers locally for extended periods during critical project phases.

Required Qualifications
  • Bachelor’s degree in Electrical Engineering (Master’s preferred).
  • 8+ years of experience in design engineering, applications engineering, or verification engineering within power electronics.
  • Strong hands-on experience with low-voltage DC-DC converter design, validation, and application support.
  • Deep understanding of power conversion topologies, power integrity, thermal considerations, and system-level performance tradeoffs.
  • Extensive comfort working in lab environments performing qualification and validation testing.
  • Proven ability to support mid-to-large customers in complex technical environments.
  • Strong communication skills and the ability to explain complex technical topics clearly to customers and internal teams.

Preferred Qualifications
  • Background in power modules used for data centers, networking, computing, or industrial systems.
  • Experience supporting field application engineering teams.
  • Mandarin language skills are a plus.

Work Environment
  • Hybrid role based in the San Jose area.
  • Work from home option when not performing lab or customer-site work.
  • Significant hands-on lab exposure using advanced power electronics platforms.
  • Close collaboration with global engineering and manufacturing teams.
