Senior Embedded DSP Engineer — High-Speed PHY & AI Silicon

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

Job summary

Google is seeking an experienced engineer in Sunnyvale to help shape TPU firmware for AI silicon. You will lead low‑level firmware and DSP control loops powering high‑speed physical‑layer interfaces and digital transceivers, aligning with AI infrastructure needs.

You will collaborate across TPU Systems, Networking Software, and HPC teams to ensure robust firmware deployment, verification, and silicon‑software co‑design for scalable AI workloads.

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 (register maps, driver latencies, boot sequencing) that impact Google's AI infrastructure.
