Senior Test Automation Engineer (Embedded)

Job Title: Senior Automation Test Engineer (Embedded) 
Salary: Up to £85,000 
Location: Cambridge (3 days on site ideally)

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 company that 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
• Proven experience building and maintaining CI/CD pipelines from the ground up.
• 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 an understanding 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.
