Position Type:

Full Time

City:

Andover, MA (onsite)

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.
• 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
