Principal Post-Silicon Validation Engineer

The role

You will lead post-silicon validation and characterization for next-generation coherent DSP ASICs. You will develop validation plans, enable first silicon bring-up, and debug complex hardware and firmware issues.

What you will do

• Lead post-silicon validation and characterization of complex ASICs and SoCs.
• Develop comprehensive validation plans.
• Enable first silicon bring-up using JTAG, scan, and embedded debug features.
• Validate high-speed interfaces including PCIe, Ethernet, SerDes, CXL, SPI, I²C, and MDIO.
• Utilize advanced lab equipment including oscilloscopes, BERTs, and protocol analyzers.
• Debug complex hardware, firmware, RTL, and system-level issues.
• Develop scalable Python-based automation frameworks.
• Validate firmware, bootloaders, device drivers, and hardware/software interfaces.
• Characterize silicon performance, power, thermal behavior, margins, and compliance.
• Support early customer engagements by reproducing and resolving system-level issues.

Required qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline.
• 8+ years of hands-on post-silicon validation, DVT, or silicon bring-up experience with complex ASICs or SoCs.
• Proven experience bringing first silicon to production in networking, communications, data center, AI, or high-performance computing products.
• Strong understanding of silicon debug methodologies and structured root-cause analysis.
• Extensive experience using laboratory equipment including oscilloscopes, BERTs, protocol analyzers, network analyzers, and logic analyzers.
• Strong knowledge of one or more high-speed protocols including PCIe, Ethernet, SerDes, CXL, USB, SPI, I²C, or similar interfaces.
• Strong Python programming skills for automation, regression development, and data analysis.
• Experience validating firmware, embedded software, drivers, and hardware/software interfaces.
• Ability to interpret schematics, understand board design, power sequencing, signal integrity, and hardware debug.
• Excellent communication skills.

Nice to have

• Experience validating coherent optical DSPs, networking ASICs, Ethernet switch silicon, AI accelerators, GPUs, storage controllers, or high-speed communications devices.
• Strong knowledge of Ethernet, PCIe, OIF, IEEE, or related compliance specifications.
• Experience with PIPE, PCS, PMA, MAC, PHY, or other physical and protocol layers of high-speed interfaces.
• Experience building scalable validation automation, regression systems, dashboards, and data pipelines.
• Familiarity with customer platform validation and hyperscale qualification processes.
• Experience mentoring engineers and leading technical initiatives across multiple engineering disciplines.
