Senior Design Specialist - SMS, MMS, Voicemail

TELUS•Edmonton, AB

About The Position

Our Mobile Edge and Messaging team is dedicated to keeping TELUS's critical communication services running reliably across the country. We manage three key technical verticals—Mobile Edge - security & media optimization, and messaging—each playing a vital role in network performance and customer experience. We're seeking a Senior Design Specialist to join the Messaging vertical, where you'll ensure end-to-end service reliability for SMS, MMS, voicemail, and anti-spam services that millions of Canadians depend on every single day. In this role, you'll balance three key responsibilities: contributing to the modernization of our infrastructure through containerization and virtualization migration, responding to critical incidents and troubleshooting complex platform issues, and building automation and monitoring solutions to prevent problems before they impact customers. You'll gain deep expertise across multiple messaging platforms and vendors through hands-on testing, implementation, and lab work on new features and services. Working closely with your team and external vendors, you'll develop the independent platform knowledge to handle sophisticated technical challenges while maintaining the reliability of our critical telecom infrastructure. We also encourage learning new technologies and changing roles within our team to keep things interesting.

Excellent written and verbal communication skills, with the ability to document solutions clearly
