## Description

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., * Lead the development and optimization of on-device and hybrid multimodal models for XR devices. Utilize techniques like prompting, few-shot learning, and post-training (e.g., quantization) to enhance performance and robustness while adhering to strict device power and latency constraints.

 * Create comprehensive evaluation plans for hybrid systems, from dataset development to defining KPIs that measure model accuracy and on-device efficiency.
 * Identify, implement, and ship the latest modeling innovations, focusing on hybrid agent architectures, orchestration between edge and cloud, multimodality, tool integrations, and personalization.
 * Prove out concepts for on-device AI features through rapid prototyping and iterative development, facilitating team testing and in close partnership with XR product teams.
 * Work closely with research scientists, engineers, and product teams to drive the technical roadmap. Foster a collaborative environment and share findings through conference publications while contributing to impactful product launches.
