We’re on the hunt for a strong Senior Automation Test Engineer with a Python background who can build test automation frameworks from scratch. This is on behalf of a companythat are working on the development of their next generation products within the telecoms space. To be successful in this role, you will need knowledge of networking protocols (I.e. TCP/IP) and a solid embedded testing background.

What will you be involved in?

• Designing and building scalable test automation frameworks from scratch (e.g. keyword-driven, data-driven) for embedded systems within the wireless telecoms domain (gNodeB, core network, UE).
• Developing and managing CI/CD pipelines for automated test execution, reporting, and continuous validation.
• Orchestrating and automating multi-node environments to simulate real-world network traffic and interactions.
• Creating and executeting test scenarios to validate system behaviour under varying traffic conditions.
• Analysing logs from both 5G protocol and network traffic perspectives to identify defects, performance issues, and bottlenecks.
• Generating test data, automate reporting, and track execution results and failures across complex test suites.
• Producing and maintaining technical documentation, including system architecture and API specifications.

Skills & Experience Essential:

• Solid experience developing test automation frameworks and hands-on experience orchestrating multi-node systems for embedded systems or telecoms

• Strong understanding of embedded systems testing, including hardware/software integration.
• Proficiency in programming languages such as Python, Java, or C++ for automation.
• Experience with network analysis and tracing tools (e.g. TCPdump, Wireshark, strace).
• Knowledge of networking protocols (TCP/IP, UDP, SCTP, 5G) and anunderstanding of networking fundamentals (IPv6, DNS, DHCP, NAT) and network security concepts.
• Experience with test frameworks and reporting tools (e.g. TestNG, JUnit, Allure, ReportPortal).
• Familiarity with containerisation and distributed environments (Docker, Kubernetes).
• Experience with network orchestration and performance testing tools (e.g. OpenStack, Xena, Ixia, Spirent).
• An understanding of the Linux networking stack (TCP/IP, UDP, SCTP, Netfilter, iptables, nftables).
• Strong analytical and problem-solving skills with the ability to diagnose complex system issues.
• Excellent communication skills and ability to work effectively in collaborative environments.
