Principal SerDes Systems Engineer
Originally posted 2 March 2026 by the employer.
This role focuses on SerDes system models for NRZ and PAM4 transceivers.
About the role
This role involves developing and maintaining SerDes system models and advanced algorithms for high-speed serial-link transceiver development, targeting PCIe (128Gbps+) and Ethernet (200Gbps+) standards.
What you'll do
- Develop and maintain SerDes system models for NRZ and PAM4 transceivers targeting PCIe (128Gbps+) and Ethernet (200Gbps+) standards.
- Run comprehensive system simulations to verify design performance across multiple protocols and channels.
- Design and propose advanced algorithms to calibrate and adapt transceivers for optimal performance.
- Correlate simulated performance with silicon measurements.
- Provide expert assistance to customers for system-level performance issues and troubleshooting.
- Contribute to lab testing and analysis for high-speed serial links.
What you'll need
- M.Sc. or Ph.D. in Electrical or Computer Engineering.
- Strong experience modeling circuits and systems in MATLAB/Simulink.
- Expertise in designing high-speed analog CMOS circuits.
- Solid understanding of DSP and communications theory, including equalization, coding, and noise/crosstalk filtering.
- Proficiency in analyzing link budgets for NRZ and/or PAM4 high-speed serial links.
- Familiarity with wireline protocols (PCIe, Ethernet, JESD204C, CPRI) and optical protocols (LINEAR, RTLR).
- Experience with circuit topologies used in high-speed SerDes Tx/Rx and Tx/Rx equalization techniques.
- Hands-on lab testing for high-speed serial links and proficiency in C/Verilog-A/SystemVerilog.
