Design Specialist II - Service Integrity Engineering Operations (4G/5G Signaling)

Our team and what we will accomplish together

The Wireless Core Network Operations team is responsible for maintaining and optimizing the reliability, performance, and integrity of TELUS signaling platforms that connect millions of customers across our 4G and 5G networks. You will be part of a team that ensures our signaling infrastructure—including DRA, DEA, SCP, SEPP, & STP —operates at peak performance 24/7. Your expertise will directly impact customer experience by proactively detecting issues, driving reliability improvements, and enabling rapid resolution of critical signaling problems. 

Together, we are modernizing how TELUS delivers world-class wireless connectivity while maintaining the security and stability our customers depend on.

What you will do

• Drive reliability and performance optimization across TELUS signaling platforms (DRA/DEA/SCP/SEPP/STP) by conducting root cause analysis, identifying improvement opportunities, and implementing operational enhancements
• Proactively monitor signaling network health, key performance indicators, and service metrics using industry-standard assurance tools (Prometheus, Grafana, Netscout, Wireshark) to detect anomalies and prevent service degradation
• Rapidly detect, analyze, and troubleshoot 4G/5G signaling issues across Diameter, HTTP/2, SS7, and SIGTRAN protocols, determining impact scope and coordinating resolution with cross-functional teams
• Collaborate with Radio, Core, Transport, Infrastructure, and Business teams to support service deployments, migrations, and operational changes while ensuring signaling integrity
• Maintain and update network architecture and operational documentation, ensuring accurate records of signaling platform configurations, procedures, and lessons learned
• Provide 24/7 operational support for signaling platforms, responding to incidents, escalations, and critical alerts to minimize customer impact and service disruption
• Leverage your knowledge of TCP/IP networking, protocol analysis, and cloud-native service environments to optimize platform performance and support infrastructure modernization initiatives
• Be part of a 24/7 on-call rotation to respond to critical signaling incidents and escalations, ensuring minimal customer impact

What you bring

• 3+ years of telecommunications operations experience with demonstrated expertise in 4G/5G network architecture and signaling platforms
• Strong knowledge of signaling protocols including Diameter, HTTP/2, SS7, and SIGTRAN, with hands-on experience troubleshooting issues across these protocols
• Proven experience with network troubleshooting and analysis tools such as Netscout, Wireshark, and protocol analyzers
• Strong understanding of TCP/IP networking fundamentals, including TCP, UDP, RADIUS, and Diameter protocols
• Demonstrated expertise in network monitoring, performance analysis, and key performance indicator (KPI) management using industry-standard assurance tools
• Strong analytical and problem-solving abilities with the capacity to work under pressure, manage multiple priorities, and respond effectively to critical incidents
• Excellent communication skills (written and verbal) with the ability to collaborate effectively across technical and business teams
• Bachelor degree in Computer Science, Computer Engineering, Electrical Engineering, or STEM-related field, or equivalent relevant operational experience

Great-to-haves

• Understanding of 3GPP architectures and reference points for 4G and 5G wireless networks, including knowledge of 3GPP, TMF, GSMA
• Experience with cloud-native assurance and monitoring tools such as Prometheus, Grafana, Jaeger, OpenSearch, or Elasticsearch
• Hands-on experience with low-level protocol implementation on SCTP, GTPv1, and GTPv2, or experience with Radio, Core, Transport, and Infrastructure product operations
• Working knowledge of cloud-native service environments and virtualization and containerization concepts (Docker, Kubernetes, OpenStack, OpenShift or similar platforms)
