Your Impact

Do you want to pioneer high-density power delivery architectures that push the absolute limits of AI infrastructure? Are you energized by taking technical ownership of complex power systems scaling up to 20kW from concept through mass deployment? In this role, you will lead the architecture, design, and optimization of innovative power delivery solutions for next-generation networking platforms and power-hungry Silicon One ASICs.

As a team we design high-current, low-voltage multiphase power stages, develop electrical schematics, optimize Power Distribution Networks (PDN), and partner closely with Hardware, ASIC, PCB Layout, SI/PI, Thermal, and Mechanical engineering teams across the entire product lifecycle. Working directly in our Caesarea lab, you will lead testing, power transient characterization, and systematic debugging to deliver record-breaking efficiency and thermal performance. We all enjoy the speed and creative ownership of a startup with the scale and benefits of a global tech giant—join our team , We are growing! and we are right next to the Caesarea train station!
