The TPU Chip Architecture and Performance Co-design team is at the forefront of optimizing Google's custom AI silicon for next-generation machine learning models. As a Senior Performance Co-Design Engineer, you will focus on conducting LLM Serving Studies. You will analyze and optimize the serving performance of emerging models and use cases on our custom hardware, while working closely with hardware architects to influence the evolution of Google’s custom ML accelerators.

The AI and Infrastructure team is redefining what’s possible. We empower Google customers with breakthrough capabilities and insights by delivering AI and Infrastructure at unparalleled scale, efficiency, reliability, and velocity. Our customers include Googlers, Google Cloud customers, and billions of Google users worldwide. We're the driving force behind Google's groundbreaking innovations, empowering the development of cutting-edge AI models, delivering computing power to global services, and providing platforms that enable developers to build the future.

Responsibilities

• Conduct comprehensive serving performance studies on (current and emerging) LLMs (1P/3P models).
• Develop and maintain advanced simulation, profiling, and modeling tools to identify bottlenecks, understand key characteristics, and project serving workload performance.
• Partner with model researchers, software, and hardware teams to co-design architectural improvements tailored to Large Language Model (LLM) inference latency and throughput.
• Drive data-backed decisions that influence the roadmap for future TPU/Cloud Silicon architectures.

Qualifications

Minimum qualifications

• Bachelor’s degree in Computer Science, Electrical Engineering, Computer Engineering, a related field, or equivalent practical experience.
• 5 years of experience in performance modeling/engineering, computer architecture, co-design, or systems engineering.
• Experience programming in C++ or Python.

Preferred qualifications

• Master's degree or PhD in Electrical Engineering, Computer Engineering, or Computer Science, with an emphasis on computer architecture.
• Experience with hardware/software co-design problems, especially performance analysis and identification at the pre-silicon stage.
• Experience enabling and optimizing large-scale ML models (e.g., LLMs, large embedding models).
• Experience with ML infrastructure, profiling tools, or deep learning inference/serving optimizations.
• Familiarity with accelerator architectures.
