Job description

from Google careers

Google Cloud’s mission is to make every business successful through AI by combining cutting-edge technology, infrastructure, and talent. 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.

Software Engineers that work for Cloud AI's team in Poland specialize in designing, building, and maintaining the scalable and reliable backend infrastructure that powers GenAI systems. Their primary focus is on the "middleware" layer, sitting between the user-facing APIs and the underlying ML models and data stores.

This role is critical for ensuring efficient model use, data flow, and overall system performance. They bridge the gap between model development and production deployment, enabling robust and performant AI/ML applications.

Google Cloud accelerates every organization’s ability to digitally transform its business and industry. We deliver enterprise-grade solutions that leverage Google’s cutting-edge technology, and tools that help developers build more sustainably. Customers in more than 200 countries and territories turn to Google Cloud as their trusted partner to enable growth and solve their most critical business problems.

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

Poland: zł364000 - zł374000 (PLN) + 15% bonus target + equity + benefits
