Job Description 3 rd Line NOC Analyst At Icomera, we build technology that keeps people connected while they’re on the move. Every day, our solutions deliver fast, reliable internet and digital services on trains, trams, buses, and coaches - supporting millions of passengers across the world. Join Icomera as a 3rd Line NOC Analyst, tackling complex issues across onboard networks where mobility, unstable links, and real-world conditions make troubleshooting anything but routine. This role is for analysts who go beyond resolving incidents—digging into networking, and system behavior to uncover the root causes behind problems others can’t explain. Job type: Full-time Workplace conditions: Hybrid Location: Gothenburg, Sweden About the Role: We’re looking for a 3rd line NOC analyst who can take on complex, cross-layer issues that go beyond configuration and require understanding how the system actually behaves under load, mobility, and failure conditions. Your mission: dig deep, untangle complex issues, and collaborate with product teams to transform uncertainty into clarity. By pinpointing root causes or uncovering the right feature ideas, you’ll help shape elegant, lasting solutions that make a real difference. Key responsibilities: Investigating escalated issues across onboard systems: intermittent connectivity, packet loss, latency spikes client experience degradation under load or poor RF conditions Analysing packet flow across: onboard LAN/Wi‑Fi → router → cellular uplinks Troubleshooting environments with: multiple WAN links (LTE/5G/LEO), NAT, QoS, VPNs fluctuating signal quality and handovers Identifying where problems occur: client side, Linux networking stack, configuration, or hardware behavior Supporting incident resolution and long-term fixes: working with software, embedded, and product teams when needed Creating tools, methods, and documentation to improve troubleshooting efficiency Requirements: Strong Linux troubleshooting skills: tcpdump, ip, iptables, logs, system behaviour Solid networking knowledge: TCP/IP, DHCP, DNS, routing, NAT, VLANs Ability to trace issues across layers: Troubleshooting across all layers of the OSI model on board and in the cloud Experience working with hardware: routers, Wi‑Fi APs, or similar network equipment Handling unclear or intermittent problems in production system The following skills we see as meritorious: Exposure to cellular networks (LTE/5G behaviour, failover, signal impact) Experience in high-availability or multi-link environments Background in NOC, escalation teams, or advanced support roles Who You Are: You are a curious mind—part detective, part problem-solver—someone who won’t stop at surface-level answers. With a strong foundation in Linux and networking, you enjoy digging into complex issues, following the data, and piecing together what’s really happening across systems. Comfortable working across layers, you persist until you understand the root cause—especially when the problem isn’t obvious.
