Senior System Performance Engineer, XR

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.

With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions.

XR System Performance Engineer, you will play a critical role in ensuring the performance excellence of XR hardware and software. You will design strategies to identify bottlenecks and implement optimizations that maintain system stability, responsiveness, and efficiency under tight latency, power, and thermal constraints.

You will bring interest and experience in optimizing microXR glasses OS and Glasses Core software stack for the audio and display smart glasses product family. Your interests will span the entire operating systems stack: boot loaders, kernels, IPC mechanisms, graphics, window composition, cameras and sensors, application frameworks, etc.

For decades, the computing revolution has reshaped our world driven by
breakthroughs in compute, connectivity, mobile, and now, AI. Google's XR
team is at the forefront of the next major leap – the convergence of AI and
XR. This is more than just new devices – it's about reimagining how we
interact with the world around us. We're building a future where
lightweight XR devices like smart glasses and headsets pair with helpful AI
to augment human intelligence, offering personalized, conversational, and
contextually aware experiences.
