AI/ML software engineers in Cloud bridge the gap between pioneering models and a massive product vehicle reaching billions. Our talent density and AI-powered tools drive rapid development, rooted in a culture of empowerment and a bias to action. In this role, you aren’t just building technology; you’re shaping the frontier of enterprise and driving the evolution of advanced models. We are dedicated to simplifying the creation, deployment, and management of production-grade AI agents. By building and supporting a comprehensive, open-source, multi-language ecosystem—highlighted by our agent development kit (ADK) and related agentic protocols we serve developers both inside and outside of Google. Our work is pivotal to forging a unified and powerful GenAI landscape for the entire developer community. As a Senior Software Engineer, you will drive the technical goals, strategy, and architecture for the open-source components and tooling of our AI Agent ecosystem, including the agent development kit (ADK). You will lead the design and development of foundational libraries, SDKs, and developer tools, managing ambiguous issues to enhance the end-to-end agent development lifecycle. This role requires technical leadership to influence and collaborate with internal, external, and cloud platform teams, shaping the roadmap and ensuring seamless integration and deployment of AI agents. You will be a key technical voice, mentoring engineers, setting standards for engineering excellence, and driving long-term investments to scale the platform and empower a vibrant developer community. The ML, Systems, and Cloud AI (MSCA) organization at Google designs, implements, and manages the hardware, software, machine learning, and systems infrastructure for all Google services (Search, YouTube, etc.) and Google Cloud. Our end users are Googlers, Cloud customers and the billions of people who use Google services around the world. We prioritize security, efficiency, and reliability across everything we do - from developing our latest TPUs to running a global network, while driving towards shaping the future of hyperscale computing. Our global impact spans software and hardware, including Google Cloud’s Vertex AI, the leading AI platform for bringing Gemini models to enterprise customers. Individual pay is determined by factors including job-related skills, experience, and relevant education or training.
