5G Development and Operations – Subscriber Data Management

Join our team and what we’ll accomplish together

The Wireless Core Network Development team is responsible for End to End network architecture, development, and operations including service orchestration and automation. The team designs, develops, maintains, and supports our Core Wireless Network and all its services. 
We work as a team to introduce the latest technology and software to enable network orchestration and automation in the fast evolving 5G ecosystem, and propel TELUS’ digital transformation.
Our team creates previously impossible solutions by leveraging the new approach to enable our customers unique and rich wireless experiences. These innovative solutions will improve the life quality of thousands while revolutionizing how everything and everyone connects.
You will own the customer experience by providing strategy, managing change and leveraging best in class security and AI to deliver reliable products to our customers. This will represent a fundamental change on how the Telecom industry works, opening the possibility of making private cellular networks globally available, sparking innovation and enabling access to the digital world to more people by providing never seen reliability at reduced costs.
