Requirements

We are looking for a Network QA Engineer to test the performance and reliability of our LTE/5G modems. You will join a dynamic team dedicated to developing and testing multi-layer networking solutions. In this hands-on role, you will configure Linux-based testbeds, perform deep-packet protocol analysis, and optimise data path throughput, latency, and stability. Beyond core connectivity, you will also lead the validation of critical IoT and higher-layer protocols, including MQTT, CoAP, and LwM2M.

Required Skills:

• Core Network Fundamentals: In-depth understanding of the OSI model, including addressing, interfaces, protocols, and Protocol Data Units (PDUs) across layers.
• Routing, Switching & Addressing: Proficiency in IP subnetting, hands-on static routing configuration, and solid theoretical knowledge of Layer 2/3/4 concepts (VLANs, MAC / ICMP, ARP / NAT, Firewall).
• Traffic & Debugging Tools: Hands-on experience debugging network traffic and measuring bandwidth using Wireshark, tcpdump, iperf, netcat, nmap, and netstat.
• Linux Command Line Proficiency: Strong proficiency in working within a Linux command line interface (CLI) environment without a graphical UI.
• Intermediate spoken and written English skills

Desired skills:

• Mobile Operator & Telecom Background: Experience working with mobile network operators, cellular infrastructure, or telecommunications protocols is a strong plus
• Environment Configuration: Practical experience configuring essential network services and protocols (DHCP, DNS, NAT, HTTP/HTTPS) and Linux network security via iptables to build testbeds
• Python Scripting: Ability to write Python scripts for test automation, data collection or log parsing.
• QA Best Practices: Experience with test case management, bug-tracking tools (e.g., Jira), and software/hardware testing lifecycles.

Job Responsibilities

• Testbed & Environment Setup: Configure and maintain Linux-based test environments, including static routing, subnetting, core network services (DHCP, NAT), and firewall rules (iptables) to simulate realistic operational and edge-case network conditions for the modem.
• Modem Testing & Validation: Design and execute functional, performance, and stability test scenarios for new features on the LTE/5G modem.
• Data Path & Traffic Analysis: Generate traffic across IP interfaces, measure throughput, latency, and jitter, and conduct deep packet capture and protocol analysis across multi-layer data paths.
• Issue Triage & Debugging: Isolate and debug connectivity failures, packet drops, and performance regressions using packet analysis tools and modem log outputs.
• Reporting: Document detailed test results, track defects, and collaborate with engineering teams to isolate root causes.
