About The Role:

We are seeking a Senior System Engineer with strong understanding and experience in 5G networks, including RAN, core, and mobile configurations. The ideal candidate will support customers with solution integration and troubleshooting, bringing hands-on experience across the full 5G network. Practical experience with supporting 5G, 4G, and Wi-Fi deployments in real-world environments is highly valued, especially in end-to-end connectivity. This role requires excellent verbal and written communication skills and a strong sense of ownership in both independent and team-based settings within a fast-paced environment.

What You’ll Be Responsible For:

1. Technical customer engagement for 5GNR, LTE, and Wi-Fi network deployments, resolving complex issues related to RAN, core network, and end-to-end connectivity.
2. Perform in-depth network performance analysis, diagnose connectivity bottlenecks, and conduct packet-level troubleshooting using tools like Wireshark.
3. Configure and optimize network switching infrastructure, including VLANs, static routes, and QoS policies, to ensure seamless solution integration within telecom environments.
4. Collaborate with customers and cross-functional teams to design, deploy, and optimize wireless network architectures for 5GNR+Wi-Fi and LTE use cases.
5. Leverage monitoring and analytics platforms (e.g., Grafana) to proactively identify, analyze, and resolve system performance issues.
6. Articulate technical solutions and root-cause analyses clearly to technical stakeholders, customers, and executives.
7. Document technical issues, configurations, and resolutions in detailed reports to support knowledge sharing and workflows.
8. Provide hands-on support during customer lab and field trials, including system integration, testing, and performance validation.
9. Lead planning and execution of customer trials, ensuring thorough preparation, successful deployment, and comprehensive documentation of outcomes.
10. Stay updated on emerging trends in wireless networks, cloud technologies, and virtualization to drive continuous improvement.

What We’re Looking For:

1. Master’s degree in Computer Science, Electrical Engineering, Telecommunications, or a related field (or equivalent experience).
2. 10+ years of experience in RAN and core integration, network validation, and wireless support.
3. Hands-on telecom experience with deploying and supporting 5G and LTE networks across RAN, core, and mobile configurations.
4. Deep expertise in 5GNR technologies including gNodeB, 5GC, and end-to-end 5G network architecture, with strong foundational knowledge of LTE systems such as eNodeB and EPC.
5. Experience configuring and testing 5G UEs (smartphones and CPEs) in customer deployments.
6. Advanced understanding of wireless network protocols (e.g., S1AP, NGAP, RRC, NAS) and their integration with cloud and edge solutions.
7. Proficiency in virtualization platforms (e.g., VMware, KVM) and containerization technologies (e.g., Docker, Kubernetes) for network function virtualization (NFV).
8. Knowledge of cloud communication protocols (e.g., HTTP/HTTPS, MQTT, WebSocket) and their application in device-to-cloud interactions.
9. Strong expertise in networking fundamentals, including firewall policies, NAT, port mapping, VLAN segmentation, and routing.
10. Proven experience in network troubleshooting, packet sniffing, and analysis using tools like Wireshark, tcpdump, and iperf.
11. Hands-on proficiency in configuring managed switches for VLANs, QoS, and basic routing (without BGP or OSPF).
12. Familiarity with observability and analytics tools (e.g., Grafana, Elastic, Spark) for radio network performance monitoring is highly desirable.
13. Willingness to travel up to 30% for live customer technical engagements.
14. Certifications such as CCNA, CCNP, or equivalent are a plus.
