Sr Power Integrity Validation Engineer; Board​/System Design

Our Mission

At Palo Alto Networks® everything starts and ends with our mission:

Being the cybersecurity partner of choice, protecting our digital way of life.

Our vision is a world where each day is safer and more secure than the one before. We are a company built on the foundation of challenging and disrupting the way things are done, and we’re looking for innovators who are as committed to shaping the future of cybersecurity as we are.

We believe collaboration thrives in person. That’s why most of our teams work from the office full time, with flexibility when it’s needed. This model supports real-time problem-solving, stronger relationships, and the kind of precision that drives great outcomes.

As a key contributor in the Platform Hardware development team, you will be responsible for the complete design cycle of Palo Alto Networks hardware including: specification; component selection; schematic entry; layout oversight; prototype bring-up, debug, and validation testing. The Hardware Engineering team is an interdisciplinary team including: mechanical engineering, signal integrity, PCB layout, and compliance. You will also collaborate cross-functionally with product management, software, operations and quality assurance.

As a member of the hardware engineer - Power design team, you will be working on various power components including the dc/dc, LDO and power switches that are crucial to power our on board devices. You will also be working very closely with the hardware, layout and lab team for on board power supply design, review, characterization and validation.
