The Role

DriveNets is seeking a highly motivated Power Integrity Engineer to join our Hardware Engineering team. In this role, you will be responsible for defining, analyzing, simulating, and validating power delivery networks (PDNs) for next-generation networking platforms supporting high-performance ASICs, advanced SerDes interfaces, optical modules, and AI-scale networking systems.

You will work closely with hardware architects, PCB designers, ASIC teams, signal integrity engineers, mechanical engineers, and manufacturing partners to ensure robust power delivery, optimal system performance, and successful product deployment.
Responsibilities

- Lead Power Integrity (PI) activities throughout the hardware development lifecycle, from architecture through production.

- Define and optimize board-level and package-level Power Delivery Networks (PDNs) for high-current networking ASICs and supporting devices.

- Perform pre-layout and post-layout PI simulations using industry-standard tools.

- Establish target impedance requirements and validate compliance across all power rails.

- Analyze DC voltage drop, AC impedance, transient response, and power distribution performance.

- Collaborate with PCB layout engineers to optimize stackups, plane structures, decoupling strategies, and power routing.

- Work closely with Signal Integrity engineers to ensure SI/PI co-optimization of high-speed interfaces.

- Develop power integrity design guidelines and best practices for next-generation networking products.

- Support schematic reviews, layout reviews, and design sign-off activities.

- Perform laboratory measurements and correlation using oscilloscopes, VNAs, power analyzers, current probes, and related equipment.

- Investigate and resolve PI-related issues during board bring-up, validation, and production.

- Collaborate with ASIC, FPGA, memory, optics, and power component vendors to optimize overall system performance.

- Drive continuous improvement of PI methodologies, simulation flows, and validation processes.
