About the Role

We are seeking a highly skilled and motivated Application Engineer specializing in High-Reliability (Hi-Rel) Power Electronics. In this role, you will serve as the crucial technical bridge between our R&D engineering team and our clients operating in mission-critical sectors (Space, Aerospace, Defense, Medical).

You will be responsible for helping customers integrate our cutting-edge power conversion technologies into environments where failure is not an option. If you thrive on solving complex electrical engineering challenges, optimizing thermal management, and working with wide-bandgap semiconductors, this role is for you.

Key Responsibilities:

  • Customer Technical Support: Act as the primary technical point of contact for tier-1 customers, assisting them with component selection, circuit design, and system integration.
  • Design-In Support: Create reference designs, evaluation boards, application notes, and simulation models (using SPICE, PLECS, or MATLAB/Simulink) to accelerate customer adoption.
  • Failure Analysis & Troubleshooting: Lead root-cause analysis investigations for field failures or qualification anomalies, leveraging standard laboratory equipment (oscilloscopes, power analyzers, thermal cameras).
  • Cross-Functional Collaboration: Partner with Product Management and R&D to feed customer requirements, market trends, and feature requests back into our next-generation product roadmap.
  • Testing & Validation: Conduct hands-on electrical and thermal characterization of power modules and discrete components under extreme high-reliability conditions.

Required Qualifications & Skills:

Education & Experience

  • Degree: Bachelor’s degree in Electrical Engineering (BSEE) or a related field required. Master’s (MSEE) or Ph.D. preferred.
  • Experience: 2–5 years of hands-on experience in power electronics design, test, or application engineering.

Technical Competencies:

  • Topology Expertise: Deep understanding of switch-mode power supply (SMPS) topologies (DC-DC, resonant converters, buck/boost, flyback, forward, and bridge configurations).
  • Hi-Rel Standards: Familiarity with high-reliability standards and harsh environment testing protocols (e.g., MIL-STD-810, MIL-STD-461, DO-160, ESCC, or automotive AEC-Q101/Q200).
  • Components: Strong knowledge of power semiconductors (MOSFETs) and a distinct advantage if experienced with Wide Bandgap (WBG) materials like Silicon Carbide (SiC) and Gallium Nitride (GaN).
  • Tools: Proficiency with PCB layout tools (Altium Designer preferred) and simulation software (LTspice, or PSpice).
  • Thermal Management: Understanding of heat dissipation, thermal interface materials, and cooling techniques in constrained spaces.

Soft Skills:

  • Strong communication skills with the ability to explain complex engineering concepts clearly to both highly technical clients and non-technical stakeholders.
  • Exceptional problem-solving mindset with a methodical approach to debugging.

What We Offer

  • Competitive salary and performance-based bonuses.
  • Comprehensive health, dental, and vision insurance.
  • 401(k) matching and retirement planning.
  • Opportunities for continuous professional development and exposure to bleeding-edge aerospace/defense tech.
  • A collaborative, innovative work environment with good work-life balance
