E2E Test Automation Engineer (Wireless Systems & Devices)
Posted Updated
- We’re looking for an E2E Test Automation Engineer to develop and maintain reliable, scalable automation for end-to-end validation of next-generation wireless systems
- The ideal candidate is a hands-on automation engineer who can develop Python-based test frameworks, troubleshoot complex system interactions, analyze logs and network traffic, and help qualify software releases through functional, regression, integration, and performance testing
- This role spans device functions, radio access, network functions, lab infrastructure, and system-level interfaces across virtualized, hardware-in-the-loop, and physical lab environments
- Develop and maintain a scalable automation framework for end-to-end validation across wireless devices, radio access systems, network functions, and lab infrastructure
- Write Python automation scripts, reusable libraries, and test harnesses for functional, regression, integration, performance, and release-qualification testing
- Automate end-to-end test scenarios such as device registration and attachment, connectivity, data transfer, recovery behavior, and system KPI validation
- Coordinate test execution across virtualized systems, embedded devices, hardware-in-the-loop platforms, and physical lab equipment
- Automate system configuration, test setup, log collection, result processing, and report generation
- Develop tools for packet capture and protocol-level analysis to verify expected system behavior across interfaces
- Measure and analyze system performance, including throughput, latency, packet loss, reliability, and other end-to-end KPIs
- Support testing with RF and networking equipment, including channel emulators, spectrum analyzers, signal generators, and traffic-generation tools
- Investigate automation and test failures by correlating logs, packet captures, device behavior, and system events across multiple components
- Distinguish product defects from test-environment, infrastructure, configuration, and automation-framework issues
- Develop and maintain automation code using Git-based development workflows and support integration with CI/CD pipelines
- Own defect lifecycle management in Jira by reproducing issues, documenting evidence and impact clearly, and tracking defects through resolution and verification
- Collaborate with device, radio, network, platform, systems, and test teams to improve test coverage, reliability, and release readiness
- Ability to work effectively in a hands-on lab environment and collaborate across multiple engineering disciplines
- Strong Python programming skills and experience building maintainable automation frameworks or test tools
- Experience developing and maintaining functional, regression, integration, or performance test suites
- Practical understanding of TCP/IP networking and experience troubleshooting connectivity and data-transfer issues
- Good working knowledge of Linux, including shell scripting, process and service management, networking, and system debugging
- Experience working with virtualized environments such as VMware, Proxmox, or similar platforms
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related discipline
- 2–5 years of experience developing test automation for wireless, networking, embedded, or distributed systems
- Experience with Git and collaborative software-development workflows
- Strong problem-solving skills and a disciplined, evidence-based approach to debugging and defect tracking
- Experience analyzing system logs and network traffic to isolate failures across multiple components
- Familiarity with CI/CD pipelines and automated test execution
- Experience with cellular or wireless-system architecture, including device/UE, radio access network, and 5G Core functions
- Experience validating end-to-end cellular registration, attachment, connectivity, and data-transfer procedures
- Familiarity with RF test equipment such as spectrum analyzers, signal generators, power meters, or channel emulators
- Experience with Wireshark, tcpdump, iperf, or similar network-analysis and traffic-generation tools
- Experience with hardware-in-the-loop testing involving embedded radio or communications hardware
- Familiarity with monitoring and visualization tools such as Grafana or Prometheus
- Exposure to Non-Terrestrial Networks, satellite communications, or LEO communication systems
