  • Oversee infrastructure lifecycle: installation, upgrades, patching, and scaling
  • Ensure high availability, redundancy, and disaster recovery (DR) readiness
  • Perform capacity planning, performance tuning, and resource optimization
  • Lead complex troubleshooting across network, compute, storage, and virtualization layers
  • Support integration of Packet Core nodes (MME, SGW, PGW, PCC, PCG, AMF, SMF, UPF, etc.)
  • Drive automation and DevOps practices (CI/CD, Infrastructure as Code)
  • Monitor systems using tools like Prometheus, Grafana, and CNOM
  • Ensure compliance with security policies, hardening, and best practices
  • Participate in incident management, root cause analysis, and escalation handling

Requirements

  • 6–10+ years of experience in telecom core networks and cloud infrastructure

  • Familiarity with security, hardening, and compliance frameworks
  • Strong ownership, problem-solving, communication, and stakeholder management skills
  • Bachelor's degree in Engineering, Computer Science, or a related field

Desired Qualifications

  • Experience with Ericsson telco cloud platforms and exposure to 5G NSA & 5G SA deployments is a plus
  • Knowledge of network slicing and edge/cloud-native architectures
  • Certifications preferred: Kubernetes (CKA/CKAD), OpenStack/VMware, or Ericsson vendor certifications

Benefits

  • Outstanding opportunity to use your skills and imagination to push the boundaries of what's possible.
  • Challenged, but not alone, joining a team of diverse innovators.
