About the job

Google's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. Our products need to handle information at massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google's needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward.

Our team develops the XLA TPU compiler used to partition, optimize, and run large machine learning models across multiple TPU devices for internal customers (e.g., Gemini, Ads, Search), and external Google Cloud customers. Gemini is using our compiler for all phases of Gemini model development (e.g., pre-training, fine-tuning, serving).

The XLA Horizontal Scaling Team's software stack includes the XLA SPMD partitioner, collective and scheduling optimizations, and code generation on TPU hardware. We also develop Megascale XLA, which enables communications between devices over Data Center Network (DCN), used to scale out to even larger machine learning models.

Google Cloud accelerates every organization's ability to digitally transform its business and industry. We deliver enterprise-grade solutions that leverage Google's cutting-edge technology, and tools that help developers build more sustainably. Customers in more than 200 countries and territories turn to Google Cloud as their trusted partner to enable growth and solve their most critical business problems.

Responsibilities

• Contribute to a compiler which scales-out machine learning models across accelerators (e.g. TPU/GPU) at Google and Google Cloud.
  
• Engage with important production teams (e.g. Gemini), understand requirements, and analyze performance opportunities.
  
• Implement critical features and performance improvements, and resolve critical production issues to increase production team velocity.
  
• Work closely with users of TPUs to improve performance/efficiency and efficiently compile programs for large-scale machine learning model training and inference across distributed accelerator devices.
