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.

Google Cloud is searching for a highly skilled and motivated engineer to optimize machine learning model performance for our customers and help them achieve maximum model performance for large scale training and inference through tuning and optimization at both software and hardware levels. In this role, you will collaborate closely with customers, write custom kernels, and develop custom solutions to meet their unique model performance requirements. A deep understanding of deep learning frameworks (like PyTorch or JAX), strong coding skills, excellent communication abilities, and a passion for mentoring junior engineers are essential for success in this role.

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.
