The Senior Power Design Engineer will collaborate closely with ASIC, Mechanical, Thermal, and Systems Engineering teams to ensure next‑generation compute hardware receives robust, reliable, and highly efficient power. This is a full‑time position supporting cutting‑edge infrastructure technologies and will be fully onsite in Saratoga, CA.

Responsibilities for the Senior Power Design Engineer include:

* Designing and developing high‑efficiency DC‑DC power conversion systems, including detailed circuit analysis, simulation, and control‑loop stabilization.

* Architecting and implementing board‑level power conversion solutions optimized for performance, reliability, availability, and cost.

* Creating advanced power supply solutions that support high‑power AI workloads and next‑generation networking platforms.

* Designing and optimizing multi‑phase, low‑voltage, high‑current power delivery systems for modern ASICs.

* Performing PCB power integrity analysis, including IR‑drop, power‑loss modeling, and full PDN optimization using industry‑standard simulation tools.

* Supporting power delivery layout for large BGA packages, ensuring proper current distribution and thermal compliance.

* Leading validation, testing, and debugging activities to ensure power supplies meet performance, reliability, and manufacturing requirements.

Qualifications for the Senior Power Design Engineer include:

* 10+ years of experience in electrical engineering, power electronics, or related fields.

* 5+ years of hands‑on experience designing power supplies and DC‑DC conversion systems.

* Deep expertise with high‑efficiency DC‑DC architectures and multi‑phase system design.

* Strong proficiency in simulation tools (SPICE or equivalent).

* In‑depth understanding of control‑loop design, stability analysis, and compensation techniques.

* Experience developing high‑current, low‑voltage solutions for vertical power delivery applications.

* Proven background designing power delivery systems for high‑power ASICs or large BGA devices.

* Strong knowledge of PCB power integrity, IR‑drop analysis, and PDN optimization.

* Familiarity with AI hardware platforms, HPC systems, or data center‑scale infrastructure.

Compensation for the Senior Power Design Engineer includes:

* Salary range: $210,000 - $265,000

* Comprehensive benefits package including Medical, Dental, Vision, 401k, PTO, holidays, and sick leave as required by law.
