Job description
The Power Applications Engineer will drive the development, validation, and adoption of onsemi's eFuse, Hot-Swap, and power-switch solutions across AI, Cloud, Networking, and advanced-computing platforms. In this role, you will develop and refine performance-verification infrastructure to ensure robust, high-quality power-tree designs. You will also work with customers to optimize onsemi content within their systems and highlight the breadth and value of our power-technology portfolio.
This role focuses on the architecture, modeling, and deployment of 48V/54V and 400V/800V power-delivery systems used in AI servers and data-center infrastructure. Emphasis areas include power-tree design, power-distribution optimization, and integrated protection strategies (eFuse, Hot-Swap, power-switch control). Success requires a hybrid skill set spanning power electronics, protection methodologies, and system-level design for high-density GPU/AI compute platforms and large-scale power-delivery clusters.
You will work closely with data-center architects, power-electronics development teams, and customers deploying next-generation AI compute infrastructure, serving as a technical interface between system requirements and onsemi's product offerings.
Responsibilities
- 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, debug, and performance benchmarking.
- Collaborate with internal design, systems, and marketing teams to shape next-generation product requirements.
- Generate technical collateral: application notes, whitepapers, reference schematics, simulation models.
Qualifications
- BS in Electrical Engineering (focus on power electronics or related field).
- Experience with high-power or high-voltage systems (48/54V or 400/800V preferred).
- Understanding of eFuse/Hot-Swap, power-switching devices, or power-tree architecture.
- Familiarity with system modeling tools (SPICE, SIMPLIS, MATLAB, etc.).
- Strong communication and customer-facing problem-solving skills.
