Software Post Silicon Validation Lead

Meet The Team

Welcome to the Post-Silicon Validation Team at Cisco Silicon One , where startup energy meets the scale of a global technology leader.
As part of Cisco’ Silicon One Group, we help deliver the silicon, optics, and hardware platforms behind Cisco’s core Switching, Routing, and Wireless products used by enterprises, service providers, public sector, and non-profit organizations worldwide.
Our team works side by side with verification engineers, designers, and cross-functional partners to validate complex ASICs across their full lifecycle and ensure outstanding product quality.
At the center of this innovation is Cisco Silicon One, the industry’s only unified silicon architecture, powering platforms from Top-of-Rack switches to web-scale data centers and critical AI infrastructure.

Your Impact

Lead validation work for complex networking ASICs, from first silicon bring-up to production.
Manage and support a small validation team, and guide daily technical work.
Own the validation plan for features, performance, power, and reliability.
Find and solve issues across silicon, firmware, drivers, and system software.
Work with architecture, SDK, and firmware teams to improve product quality, stability, and test coverage.
KEY RESPONSIBILITIES:

• Lead post-silicon validation and debug for networking ASIC projects.
• Manage tasks and technical direction for a small validation team.
• Build and run validation plans for function, performance, power, and reliability.
• Drive silicon bring-up, stepping checks, and production readiness.
• Develop validation tools and automation using C/C++ and Python.
• Run stress and long tests to find hidden silicon problems.
• Debug hardware and software issues in the lab.
• Validate networking features and interfaces (for example Ethernet, PCIe, SerDes, DDR, SPI, I2C, UART).
• Add tests to regression flows and track progress until closure.
• Document results, issues, and recommended fixes clearly.

Minimum Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field, with 5+ years of post-silicon validation and debug experience.
• Strong experience in C/C++ for low-level or system-level development. Python scripting experience for test automation and analysis.
• Hands-on hardware-software co-debug experience in lab environments.
• Experience validating networking architectures/protocols and debugging high-speed interfaces (for example PCIe, DDR, SerDes, USB, SPI/I2C/UART).

Preferred Qualifications:

• Direct management experience.
• Experience with networking ASICs, switches, routers, or NPUs.
• Knowledge of Ethernet standards, PCIe, and high-speed SerDes.
• Experience with Linux kernel, drivers, and networking stack.
• Familiarity with traffic generators and packet/protocol analyzers.
• Experience with performance benchmarking, latency analysis, and throughput optimization.
