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.

Google Ads is the programmatic engine and data bedrock that powers businesses and connects customers globally. As a Senior Software Engineer on the Ads Data Layer ADL Infrastructure team, you will design the next generation of distributed storage, caching, and data processing architectures that underpin Google’s commercial systems.

Due to global infrastructure capacity constraints, this team’s mandate has evolved beyond standard resource optimization. You will lead a critical, multi-year re-architecture of the core database stack to ensure operational resilience and business continuity. This involves redesigning how the platform manages replication, caching, and redundancy to scale sustainably while minimizing resource consumption. Additionally, you will pioneer the integration of LLM-based autonomous systems to automate and enforce resource governance across the organization.

Google Ads is helping power the open internet with the best technology that connects and creates value for people, publishers, advertisers, and Google. We’re made up of multiple teams, building Google’s Advertising products including search, display, shopping, travel and video advertising, as well as analytics. Our teams create trusted experiences between people and businesses with useful ads. We help grow businesses of all sizes from small businesses, to large brands, to YouTube creators, with effective advertiser tools that deliver measurable results. We also enable Google to engage with customers at scale.

Individual pay is determined by factors including job-related skills, experience, and relevant education or training.

US: $174000 - $252000 (USD) + 15% bonus target + equity + benefits
