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.

  • 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.
  • BS/MS 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.
