With your technical expertise you will manage project priorities, deadlines, and deliverables. You will design, develop, test, deploy, maintain, and enhance software solutions. 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 optimise experimental designs. 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. The Google Cloud AI Research team addresses AI challenges motivated by Google Cloud’s mission of bringing AI to tech, healthcare, finance, retail and many other industries. We work on a range of unique problems focused on research topics that maximise scientific and real-world impact, aiming to push the state-of-the-art in AI and share findings with the broader research community. We also collaborate with product teams to bring innovations to real-world impact that benefits our customers.

Responsibilities

• Own projects end-to-end, from initial scientific research concepts through software design, testing, deployment, and performance analysis.
• Build and deploy agentic AI systems, implementing multi-agent prompting techniques and asynchronous task execution frameworks.
• Drive technical decisions and full-stack software development using Python, C++, and Google's core back-end components.
• Design and establish robust evaluation pipelines, automated test suites, and diagnostic datasets to measure agent performance under extreme scale.
• Collaborate on research with Google DeepMind, Google Research, and university labs to solve complex scientific problems, while mentoring junior engineers and advocating engineering quality.
