The role
From Google's own posting.
At Google, we put our users first, and the Android XR team is building the future of how users experience the world through augmented and virtual reality. As the Principal SWE for Multimodal LLM (M-LLM) Post-Training & Execution, you will lead the critical efforts to take state-of-the-art research models and transform them into production-ready features for the XR platform. This role is uniquely positioned at the intersection of model alignment and high-performance execution. You will ensure our models are not only intelligent but also safe, reliable, and optimized for the real-time demands of XR environments. Your work will empower XR devices to "see" and "understand" the world in ways never before possible.
The Platforms and Devices team encompasses Google's various computing software platforms across environments (desktop, mobile, applications), as well as our first party devices and services that combine the best of Google AI, software, and hardware. Teams across this area research, design, and develop new technologies to make our user's interaction with computing faster and more seamless, building innovative experiences for our users around the world.
Individual pay is determined by factors including job-related skills, experience, and relevant education or training.
