Position Overview
Inabia is seeking a highly skilled Senior Network Test Engineer to support advanced testing across 5G/LTE, Wi‑Fi, and broadband/IP networking environments for a leading telecommunications program based in London. This role blends wireless test engineering with enterprise and broadband networking validation, requiring hands‑on experience testing radio networks, IP connectivity, and customer‑premises equipment (CPE) in both laboratory and field environments. Engineers with strong LTE/5G RAN or drive‑testing backgrounds who also possess broadband/IP networking expertise are strongly encouraged to apply.
Key Responsibilities
- Broadband & CPE / Gateway Validation: Test residential and enterprise routers, gateways, modems, mesh Wi‑Fi systems, and CPE devices. Validate performance, reliability, and stability across fiber, DSL, wireless broadband, and Ethernet backhaul. Execute LAN/WAN configuration workflows, device onboarding, and end‑to‑end connectivity validation.
- IP Networking, Routing & VPN Testing: Configure and validate IPv4/IPv6, subnetting, VLANs, DHCP, DNS, NAT, port forwarding, and firewall rules. Test VPN technologies including IPsec, SSL VPNs, WireGuard, and OpenVPN. Troubleshoot Layer 2–Layer 7 connectivity using tools such as Wireshark, tcpdump, traceroute, and iPerf.
- Testbed Setup & Environment Ownership: Build and maintain test environments combining broadband routers, switches, servers, VPN endpoints, and test tools. Ensure test repeatability through documentation, configuration management, and version control. Integrate new firmware, OS builds, and network parameters into test cycles.
- Tools, Log Analysis & Reporting: Use tools such as Wireshark, tcpdump, iPerf, and Raspberry Pi. Perform deep log analysis (RRC, NAS, SIP, RTP/RTCP, system logs) to identify root causes across wireless and IP layers. Produce clear test plans, defect reports, KPI dashboards, and root‑cause analyses. Collaborate closely with broadband engineers, device OEMs, and network operators.
Required Qualifications
- Professional experience in broadband/CPE validation, IP networking. CCNA strongly preferred.
- Strong understanding of IP networking fundamentals (routing, VLANs, NAT, firewalls, DHCP, DNS).
- Hands‑on experience with network test and diagnostic tools (Wireshark, iPerf, tcpdump).
- Ability to design, configure, and troubleshoot complex testbeds across wireless and IP domains.
- Strong analytical, troubleshooting, and documentation skills.
- Fluent or professional working proficiency.
