About the job

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.

As part of a global team, you will lead the full lifecycle of projects that protect Google's users and business-critical products, including our latest generative AI experiences. You will be responsible for designing, building, and scaling the next generation of our threat intelligence and content safety solutions.

As the Core team, we have a mandate and a unique opportunity to impact important technical decisions across the company.
