In this role, you will lead and contribute to greenfield deployments of the Mavenir 4G/5G Core, while helping shape and mature Core operations over time. You will serve as a technical leader for complex network incidents, providing escalation support and ensuring stability, performance, and rapid service restoration across IMS, EPC, and 5GC domains. This position requires hands-on troubleshooting of critical network events, including deep protocol-level analysis and root cause resolution across multi-vendor environments. You will also play a key role in supporting cloud-based Core deployments and driving continuous operational improvement. Partnering across engineering and operations teams, you will help define best practices and strengthen overall Core reliability. Success in this role requires strong technical depth, proactive ownership, and the ability to lead incident response in a 24x7 environment.
What You'll Do:

    • VoLTE/VoNR call flows
    • Data session establishment failures
  • Lead Major Incident Management (MIM) calls for high-severity core outages
  • Conduct deep Root Cause Analysis (RCA) using logs, traces, KPIs, and probe captures
  • Correlate alarms and performance metrics to prevent false positives and reduce MTTR
  • Perform cloud-native core deployments in Kubernetes and AWS-based environments
  • Lead collaboration activities with RAN, Transport, and Cloud teams to resolve cross-domain issues
  • Validate software upgrades, patches, and configuration changes in production
  • Create and maintain SOPs, runbooks, and troubleshooting documentation
  • Mentor junior engineers and provide technical training on Core network troubleshooting
  • Ensure SLA/KPI compliance for availability, call success rates, and session setup times
  • Participate in 24x7 on-call rotation and major incident bridge support

What You'll Need to Succeed:
  • Bachelor's degree in Telecommunications, Computer Science, Engineering, or related field; post-graduate degree preferred
  • 10+ years of experience in telecom Core network operations
  • Extensive, practical experience with a 4G/5G Core
  • Deep understanding of:
    • 4G/5G Core architecture (EPC & 5GC SBA architecture)
    • IMS core and VoLTE/VoNR call flows
    • Diameter, SIP, GTPv2, PFCP, HTTP/2
  • Experience working in a cloud-native/Kubernetes environment
  • Experience with containerized network functions (CNFs)
  • Strong Linux command-line troubleshooting skills
  • Experience analyzing packet captures using Wireshark or similar tools
  • Familiarity with Kafka feeds and performance monitoring integrations
  • Ability to perform structured RCA and document findings clearly
  • Strong communication skills, with the ability to lead technical bridges and confidently present products, deliverables, analyses, and/or issues
Things That Would be Great if You Brought to the Table:
  • Knowledge of 3GPP practices and requirements
  • AWS certification (i.e., AWS Certified Cloud Practitioner, AWS Certified Advanced Networking, AWS Certified AI Practitioner, etc).
  • Kubernetes certification (CKA/CKAD)
  • Experience operating 4G Core networks (Mavenir is a plus)

  • Basic understanding or working knowledge of satellite-to-cell integration and 4/5G NTN architecture
  • Hands-on experience with Grafana dashboard development and alarm correlation
  • Experience with Viavi or probe-based call tracing
  • Understanding of CI/CD pipelines for telecom cloud deployments
  • Technical industry certification in Network+ or Linux (RedHat, CentOS, etc.)
  • Experience with Core Cloud operations and best practices is highly desirable
We'll also need you to:
  • Travel up to 10%, as needed to support program-related activities

Work Environment:
This position primarily works in an office setting and is largely sedentary with the majority of the position working with a computer. The role typically requires the use of basic office equipment such as a phone, video, computer, keyboard, mouse, and printer.
