SerDes Application Design Expert - CA, San Jose, United States
Originally posted 6 October 2026 by the employer.
About the role
This role involves driving applications, firmware, and validation for high-speed serial interface IP across electrical and optical domains. The scope includes bridging SerDes IP design teams and SoC/system integrators, developing low-level firmware, and architecting characterization and validation solutions for PCIe, Ethernet, and optical links.
What you'll do
- Be involved in first-silicon bring-up of SerDes PHYs across PCIe and Ethernet protocols.
- Serve as the technical escalation point for customer SerDes issues across pre-silicon, bring-up, and production phases.
- Drive PCIe compliance, Ethernet IEEE compliance, and interop testing.
- Design, develop, and debug embedded firmware for high-speed SerDes systems spanning electrical and optical domains.
- Validate and characterize SerDes PHY functionality and performance against design targets, product requirements, datasheets, and industry standards.
- Develop test automation with advanced scripting and programming skills to improve test coverage, data analysis efficiency, and demo/customer-support tooling.
What you'll need
- Experience with first-silicon bring-up of SerDes PHYs.
- Experience as a technical escalation point for customer SerDes issues.
- Experience driving PCIe compliance, Ethernet IEEE compliance, and interop testing.
- Ability to design, develop, and debug embedded firmware for high-speed SerDes systems.
- Experience validating and characterizing SerDes PHY functionality and performance.
- Advanced scripting and programming skills for test automation.
Nice to have
- Knowledge of physical-layer specifications and industry standards such as PCIe, IEEE 802.3 Ethernet, and OIF.
- Experience in producing quality firmware for mixed-signal systems.
- Hands-on experience with full-stack lab instruments such as high-speed scopes, BERT, VNA, and other associated lab equipment.
- Experience in SerDes electrical compliance for industry standards such as PCIe and Ethernet.
- Experience in scripting test automation, demo GUIs, and customer-support scripts.
