Hybrid SerDes Firmware Engineer – PCIe/IEEE PHY

Advanced Micro Devices; San Jose (CA); Hybrid; USD 150,000 - 210,000; Full time

Job summary

AMD is seeking a SerDes Firmware Engineer in San Jose, CA, to design and develop firmware bridging high-speed electrical SerDes with silicon photonics and optical subsystems.

You will work with firmware, hardware, system architects, and validation teams to enable robust control, calibration, and optimization of next‑gen SerDes solutions integrating PICs and high‑performance electrical interfaces.

Qualifications

• Bachelor’s or Master’s degree in Computer science, Computer Engineering, Electrical Engineering, or equivalent.
• Experience with low-level firmware for high-speed SerDes and mixed-signal systems preferred.
• Knowledge of PCIe and IEEE 802.3 physical-layer concepts advantageous.

Responsibilities

• Design, develop, and debug embedded firmware for high-speed SerDes systems across electrical and optical domains.
• Implement firmware control for silicon photonic components (modulators, photodetectors, lasers, heaters, tunable elements).
• Develop firmware interfaces for electrical SerDes PHYs including configuration, monitoring, diagnostics, and adaptation hooks.
• Define and implement calibration, bring-up, and closed-loop control algorithms (thermal tuning, bias control, optimization, link margining).
• Collaborate with electrical, optical, and mixed-signal hardware teams to define control, telemetry, and debug requirements.
• Integrate firmware with lab test infrastructure, production test, and characterization systems to support validation and manufacturing.
• Support silicon bring-up, debug, and performance tuning across pre-silicon, post-silicon, and production phases.
