About the Job

Requirements

A Bachelor of Science degree in Electrical Engineering, with a focus on power electronics or a related field, and 0–2 years of relevant experience.
Experience with high-power or high-voltage systems, such as 48/54V or 400/800V systems, is preferred.
Understanding of eFuse/Hot-Swap, power-switching devices, or power-tree architecture.
Familiarity with system modeling tools such as SPICE, SIMPLIS, or MATLAB.
Strong communication and customer-facing problem-solving skills.
Candidates must be authorized to work in the U.S. without current or future visa sponsorship.

Responsibilities

Support development, testing, and application of eFuse, Hot-Swap, and power-switch solutions for AI, cloud computing, networking, and other advanced electronics platforms.
Evaluate product performance, develop validation test setups, and help customers implement solutions in their system designs.
Learn how power-tree architectures are designed and optimized, assist with system modeling and characterization, and help evaluate protection technologies to improve system reliability and efficiency.
Collaborate with applications, design, marketing, and systems engineers to understand customer requirements and support technical solutions.
Develop reference designs, evaluation platforms, and validation infrastructure for eFuse/Hot-Swap and power-switch solutions.
Perform system modeling, power-tree analysis, and protection-strategy optimization.
Support customers with design reviews, system bring-up, debugging, and performance benchmarking.
Collaborate with internal design, systems, and marketing teams to shape next-generation product requirements.
Generate technical collateral, including application notes, whitepapers, reference schematics, and simulation models.

Desired Qualifications

Internship, co-op, undergraduate research, or senior design project experience focused on high-power or high-voltage systems is highly valued and may be considered in lieu of professional experience.

As an Associate Applications Engineer, you will support the development, testing, and application of onsemi's eFuse, Hot-Swap, and power-switch solutions for AI, cloud computing, networking, and other advanced electronics platforms. Working alongside experienced engineers, you will gain hands-on experience evaluating product performance, developing validation test setups, and helping customers implement onsemi solutions in their system designs.

In this role, you will contribute to power-delivery solutions used in next-generation computing and data-center applications. You will learn how power-tree architectures are designed and optimized, assist with system modeling and characterization activities, and help evaluate protection technologies used to improve system reliability and efficiency.

You will collaborate with applications, design, marketing, and systems engineers to understand customer requirements and support technical solutions using onsemi products. This position offers an excellent opportunity for recent graduates and early-career engineers to develop expertise in power electronics, semiconductor applications, and customer-facing technical support while working with emerging AI and data-center technologies.
