• Ability to drive independent, research-adjacent software development and translate academic theories into concrete, scalable products.
• Excellent track record of technical or scientific contributions to complex, large-scale projects.

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.

With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions.

As a Staff Research Software Engineer (R-SWE), you will act as a principal technical bridge, translating scientific AI research into robust, scalable, and intuitive software systems. You will lead the design and implementation of highly multi-agent reasoning models while collaborating with deep learning researchers, product managers, and external scientific partners.

You will lead software engineering for the Co-Scientist team in Zurich. Co-Scientist is a multi-agent AI system built on Gemini designed to act as an autonomous virtual scientific colleague. It utilises a "generate, debate, and evolve" approach to accelerate scientific discovery enabling researchers to synthesize literature, evaluate hypotheses, and optimize experimental designs.

Responsibilities

• Own projects end-to-end, leading teams from initial scientific research concepts through software design, testing, deployment, and performance analysis.
• Architect, build, and deploy agentic AI systems, coordinating multi-agent prompting techniques and asynchronous task execution frameworks.
• Drive technical decisions, sound architectural choices, and full-stack software development using Python, C++, and Google's core backend components.
• Design and establish robust evaluation pipelines, automated test suites, and diagnostic datasets to measure agent performance under extreme scale.
• Drive collaborative research with Google DeepMind, Google Research, and university labs to solve complex, open-ended scientific problems. Provide technical leadership, mentor junior engineers, and advocate engineering quality across the organisation.
