E2E Test Automation Engineer — Wireless Systems & Devices

Team: Engineering Operations

Location: Santa Clara, CA

Commitment: Full-Time

Workplace Type: onsite

Salary:

What you will do:

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.

What you bring to this role:

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.
Strong Python programming skills and experience building maintainable automation frameworks or test tools.
Good working knowledge of Linux, including shell scripting, process and service management, networking, and system debugging.
Practical understanding of TCP/IP networking and experience troubleshooting connectivity and data-transfer issues.
Experience analyzing system logs and network traffic to isolate failures across multiple components.
Experience developing and maintaining functional, regression, integration, or performance test suites.
Experience with Git and collaborative software-development workflows.
Familiarity with CI/CD pipelines and automated test execution.
Experience working with virtualized environments such as VMware, Proxmox, or similar platforms.
Strong problem-solving skills and a disciplined, evidence-based approach to debugging and defect tracking.
Ability to work effectively in a hands-on lab environment and collaborate across multiple engineering disciplines.

Nice to have:

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.

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
