Packet Core & Cloud Infrastructure Subject Matter Expert (SME) at Ericsson

About this opportunity

• We are looking for a Packet Core & Cloud Infrastructure SME to join our team.
• In this role, you will be at the intersection of telecom core network expertise and cloud platform engineering — responsible for the architecture, deployment, and operations of packet core systems running on virtualized and cloud-native infrastructures.
• You will play a critical part in ensuring resilient, scalable, and high-performing environments that power 4G/5G services at scale.
• This is an opportunity to work in a highly technical, fast-paced environment alongside RAN, transport, IT, and vendor teams — driving innovation through automation, DevOps, and cloud-native transformation.

What you will do

• Design and manage cloud infrastructure supporting Packet Core (EPC, 5G NSA & 5GC)
• 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

The skills you bring

• Bachelor's degree in Engineering, Computer Science, or a related field
• 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
• Certifications preferred: Kubernetes (CKA/CKAD), OpenStack/VMware, or Ericsson vendor certifications
• 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
• 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
• Familiarity with security, hardening, and compliance frameworks
• Strong ownership, problem-solving, communication, and stakeholder management skills.
