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.

The Go Google3 team is responsible for integrating the Go programming language across Google’s internal ecosystem for first-party developers. We own and optimize the Go toolchain, core libraries, build system integrations, and developer tooling within Google3, ensuring high performance, safety, and operational scalability.

Go is essential for modern AI systems, serving as a primary language for agent harnesses and runtime frameworks like Beyond Agency, Jetski, and the Gemini App. Furthermore, Go's fast start-up times and zero-dependency single-binary distribution make it ideal for creating the sidecars, CLI tools, and environment integrations that agents frequently invoke.

The Core team builds the technical foundation behind Google’s flagship products. We are owners and advocates for the underlying design elements, developer platforms, product components, and infrastructure at Google. These are the essential building blocks for excellent, safe, and coherent experiences for our users and drive the pace of innovation for every developer. We look across Google’s products to build central solutions, break down technical barriers and strengthen existing systems. As the Core team, we have a mandate and a unique opportunity to impact important technical decisions across the company.

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

Germany: €106000 - €108000 (EUR) + 15% bonus target + equity + benefits
