- Deploy and support virtualized (VNF) and cloud-native (CNF) network functions
- Manage cloud platforms (OpenStack, Kubernetes) for telecom workloads
- 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
- Solid understanding of 2G/3G/4G EPC and 5G Core architectures, including call flows, signaling, and interfaces
- Protocol knowledge: GTP, Diameter, SCTP, PFCP, HTTP/2
- Hands-on experience with OpenStack (preferred for telecom cloud) and Kubernetes (for CNFs)
- Strong understanding of compute, storage, and networking in cloud environments, including virtualization and container orchestration
- Strong troubleshooting and analytical skills with the ability to operate in 24/7 critical environments
- 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.
- Opportunity to craft what comes next.
- Encouraging a diverse and inclusive organization is core to our values.
