Senior 5G Systems Engineer

We are seeking a Senior 5G Systems Engineer to lead the deployment, integration, and operational support of Private 5G Standalone (5G SA) enterprise solutions. Positioned at the entry to mid-range of our Senior engineering track, this hands‑on role bridges Linux systems engineering, enterprise networking, and 5G cellular core architecture.

You will be responsible for taking Private 5G networks from initial deployment to steady‑state operations, performing deep stack troubleshooting from the underlying Linux OS and transport layer up through the gNodeB and 5G SA Core services.

• Install, configure, and commission Private 5G SA Core and RAN components across customer sites and edge environments

• Diagnose complex, end-to-end performance issues across the entire stack—from Linux kernel/OS networking parameters, IP routes, and firewall rules up to gNB connectivity, 5G SA Control Plane protocols (NGAP, NAS), and User Plane performance (UPF).

• Manage and optimize Linux-based hardware and virtualized runtime environments supporting 5G network functions (including containerized/K8s or virtualized deployments.

• Configure, maintain, and support Layer 2 and Layer 3 networking infrastructure, VLANs, routing protocols, VPNs, and enterprise security integrations (firewalls/NAT) tied to the 5G transport network.

• Provide tier-3 escalation support for private cellular installations, ensuring maximum network uptime, strict SLA adherence, and prompt issue resolution.

• Maintain accurate topology diagrams, configuration archives, deployment scripts, and standard operating procedures (SOPs) for site installations.

• 5+ years of hands‑on experience supporting and maintaining systems within a mobile/telecom environment, with direct exposure to 5G Standalone (5G SA) architecture.
• Proficiency in Linux OS administration (Ubuntu/Debian, RHEL/CentOS), including system diagnostics, shell scripting, process management, and networking configuration (iproute2, iptables/nftables, systemd).
• Strong foundational understanding of switching, routing (OSPF, BGP, static), VLANs, Subnetting, IPsec/VPNs, TCP/IP, and packet analysis using tools like Wireshark or tcpdump.

• Practical familiarity with 5G SA core network elements (AMF, SMF, UPF, NRF), RAN interfaces (N1, N2, N3), and session management workflows.

• Own reliable transport and a valid driver’s license (required for potential customer site visits and deployments).

• Bachelor’s Degree in Computer Science, Electrical Engineering, Information Technology, or a related field.
• Experience with containerization technologies (Docker, Kubernetes/K8s) or cloud-native infrastructure platforms (Open Shift, MicroK8s, AWS EKS).
• Exposure to Private Wireless/Enterprise LTE/5G vendor hardware and software solutions (e.g., Celona, Druid Software, Aarna, Athonet, Ericsson, Nokia).
• Vendor or industry certifications (e.g., CCNA/CCNP, Linux Foundation CKA/LFCS, or cellular-specific training).

• A structured, analytical approach to isolating network vs. OS vs. application layer faults.
• Ability to drive field deployments and resolve production outages with minimal supervision.
• Strong technical writing and verbal communication skills for interfacing with client IT teams and internal engineering leads.
