About the job
As a Principal Software Engineer for Global Network Core (GNC), you will pioneer the technological vision for a critical mandate. You will discover the defining technologies and forge the architectural path for Google’s planet-scale Wide Area Network (WAN), ultimately empowering our largest, most demanding internal and external AI/ML customers with a backbone network engineered for unmatched performance.
In this role, you will make high-stakes technical architecture decisions and deep-dive into complex distributed systems and network operations. You will navigate extreme scale and ambiguity, driving cross-functional alignment across AI2 and DeepMind. In addition, you will not only ensure our network foundation stays ahead of explosive capacity demands, but also build the most optimal, high-performance network to power AI training and inference. By acting as a pivotal liaison between Google's internal engineering and broader academic and industry research communities, you will guarantee our architecture continuously outpaces industry standards.
To be effective in this role, you must seamlessly flex between technical depth and broad strategic influence. You will be expected to foster a welcoming environment by treating everyone with respect and actively seeking out perspectives, especially during complex architectural disagreements. You must be a highly dependable teammate, taking full responsibility for the success and failure of these critical systems, and delivering high-quality work aligned with our hybrid, three-day-a-week in-office model. Finally, you must collaborate effectively—communicating clearly, identifying conflicting goals across partner organizations, and proactively finding ways to increase alignment to arrive at the best collective outcomes for Google.
