Software Post Silicon Validation Engineer

About the role

Cisco's Silicon One team builds hardware platforms central to the AI era, powering its core Switching, Routing and Wireless products. As a Software Post Silicon Validation Engineer you sit at the junction between firmware, device drivers and silicon validation, designing scalable software solutions, automated frameworks and tools that stress and validate chip functionality across process, voltage and temperature corners.

Key responsibilities

• Develop automated regression suites for functional validation, traffic stress testing and characterization to detect and root-cause issues across switching and routing devices.
• Build and maintain Python-based test frameworks, automated test suites and validation libraries.
• Implement software that interacts with low-level device drivers, register maps and high-speed interfaces (PCIe, Ethernet, SerDes, I2C, SPI).
• Debug hardware-software interactions and silicon anomalies in the lab alongside RTL, firmware, hardware and other teams.
• Analyze validation logs, parse performance datasets and track test coverage progress through closure.

Required profile

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science or equivalent.
• 3+ years of practical experience in embedded software: ASIC bring-up, test automation or post-silicon validation.
• Preferred: experience validating high-speed networking ASICs or Ethernet PHYs, and hands-on debugging on physical boards in a lab.

Required skills

• Solid knowledge of object-oriented programming and design, applied to test development, data analysis and lab equipment automation.
• Git version control and collaborative workflows (branching, merging, code reviews).
• Preferred: C/C++ for low-level drivers, Linux, device drivers and memory-mapped I/O.
• Preferred: CI/CD concepts, Python and VISA/SCPI for automating test benches and instruments, and familiarity with hardware interfaces and register maps.
