Embedded DSP Engineer for High-Speed PHY & AI Silicon

Google LLC; Sunnyvale (CA); On-site; USD 192,000 - 278,000; Full time

Job summary

Google LLC in Sunnyvale, CA is seeking a highly experienced embedded firmware engineer to shape and lead the firmware roadmap for high-speed physical-layer interfaces and DSP-driven transceiver control. You will bridge hardware and software across TPU-related silicon for AI/ML applications.

The role emphasizes designing RTOS or bare-metal firmware, monitoring diagnostics, and integration with global TPU systems while contributing to scalable, high-performance AI hardware.

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, a related technical field, or equivalent practical experience.
• 10 years of industry experience in embedded systems/firmware, communication systems engineering, or DSP development.
• Experience developing embedded software (C/C++) for high-speed physical-layer interfaces (PHY), digital transceivers, or communication subsystems.

Responsibilities

• Define the long-term firmware roadmap and hardware-software partitioning for physical-layer interfaces, determining the optimal balance between hardware-fixed logic and programmable firmware.
• Architect advanced 'in-situ' monitoring systems and firmware-driven diagnostics to track physical-layer link health, BER trends, and channel quality across millions of ports in real-time.
• Design, model, and implement bare-metal or RTOS firmware to control high-speed transceivers, managing real-time adaptive loops, clock and data recovery (CDR), and physical-layer calibration.
• Partner with TPU Systems, Networking Software, and HPC teams to ensure silicon firmware integrates seamlessly with global cluster management and collective communication frameworks.
• Identify and de-risk hardware-software interface bottlenecks (e.g., register maps, driver latencies, and boot-up sequencing) that impact Google's AI infrastructure.
