Staff Software Engineer, Tech Lead, Multimodal AI for Glasses and XR

Overview

As a Software Engineer on the XR AI Systems team, you will architect and build distributed, asynchronous AI systems spanning smart glasses, mobile, and cloud. You will lead end-to-end integration of multimodal models into production, focusing on uncertainty-driven routing, calibration, abstention, and verification. You will optimize performance and reliability across device-to-cloud boundaries, balancing latency, bandwidth, energy, and cost. You will partner with ML researchers and hardware teams to design edge/mobile inference pipelines and scalable cloud serving, while delivering production observability and debugging tools. This role offers impact at scale, shaping the next generation of,
