Power Engineer - Silicon One

About the role

Cisco Silicon One designs hardware platforms central to the AI era, powering Cisco's Switching, Routing and Wireless products. This role leads the architecture, design and optimization of power delivery solutions for next-generation networking platforms and Silicon One ASICs, working in the Caesarea lab.

Key responsibilities

• Design high-current, low-voltage multiphase power stages and develop electrical schematics
• Optimize Power Distribution Networks (PDN) and partner with Hardware, ASIC, PCB Layout, SI/PI, Thermal and Mechanical teams across the product lifecycle
• Lead testing, power transient characterization and systematic debugging to deliver efficiency and thermal performance
• Take technical ownership of complex power systems scaling up to 20kW from concept through mass deployment

Required profile

• B.Sc. in Electrical Engineering or equivalent practical experience
• 3+ years of experience as a Power Design Engineer, with a proven track record of designing, delivering and testing complex power systems
• Strong experience designing DC-DC power converters, including Buck converters and multiphase voltage regulator modules (VRMs)
• Experience designing high-current, low-voltage power delivery solutions for ASICs, FPGAs, CPUs or high-performance processors

Preferred qualifications

• Understanding of PDN design, decoupling strategies and Power Integrity (PI) principles
• Experience with PI simulations, PDN impedance analysis, voltage droop modeling and decoupling optimization
• Experience analyzing transient response, output voltage ripple, power losses and loop stability
• Experience with power sequencing, voltage/current monitoring, telemetry and fault protection
• PCB layout knowledge for high-current power delivery, including current density, copper losses and thermal management
• Lab power test equipment such as high-bandwidth oscilloscopes, electronic loads and precision current probes
