Principal SerDes Systems Engineer

Job Title

Principal SerDes Systems Engineer

Role Summary

Lead system-level development and validation of high-speed SerDes transceivers (PAM4) for PCIe and Ethernet standards. Work across analog, digital, and hardware teams to create models, verify performance through simulation and silicon correlation, and provide system-level technical support to customers.

Experience Level

Senior (Principal level). Requires 8+ years of relevant experience.

Responsibilities

Contribute technical leadership in modeling, simulation, and validation of high-speed serial-link transceivers across protocol and channel variations.

• Develop and maintain SerDes system models for PAM4 transceivers targeting PCIe (128Gbps+) and Ethernet (200Gbps+) standards.
• Run comprehensive system simulations to verify and sign off design performance across multiple protocols and channels.
• Design and propose advanced algorithms for calibration and adaptation of transceivers.
• Correlate simulated performance with silicon measurements and support post-silicon debugging.
• Support customers on system-level performance issues and troubleshooting.
• Collaborate with analog, digital, and hardware engineers and contribute to lab testing and analysis.

Requirements

Key technical skills and experience required. Education and years of experience are summarized separately below.

• Extensive experience modeling circuits and systems in MATLAB/Simulink.
• Strong understanding of DSP and communications theory, including equalization, encoding, and noise/crosstalk filtering.
• Proficiency in analyzing link budgets and performance for PAM4 high-speed serial links.
• Practical experience with wireline protocols (PCIe, Ethernet, JESD204C, CPRI) and optical protocols.
• Familiarity with circuit topologies used in high-speed SerDes Tx/Rx and Tx/Rx equalization techniques.
• Hands-on lab testing experience for high-speed serial links.
• Proficiency in C, Verilog-A, and SystemVerilog; Python is a plus.

Education Requirements

M.Sc. or Ph.D. in Electrical or Computer Engineering. The role specifies 8+ years of relevant experience at the Principal level.
