The Automation & Innovation Department builds solutions powered by AI, GenAI, process automation (RPA, BPA, AIM) and data analytics/ML models running in GCP, AWS and Kubernetes 🤖☁️. We deliver a wide range of projects across T-Mobile - from network operations to sales and customer care, plus internal and international initiatives - with a strong focus on data platforms and data engineering (data lake/warehouse in BigQuery, ETL/ELT orchestration, data governance, data quality and security). Our portfolio includes things like conversational assistants for HR and sales, knowledge search tools for consultants, employee development apps or proactive customer communication systems.

We work in a fast, flexible environment with a startuplike mindset — we value creativity, rapid experimentation, and technologies that genuinely make teams’ work easier and improve customer experience. By combining AI + automation + data, we build solutions that shape the future of processes, services and technology at T-Mobile 🚀.
