Embedded Test Engineer

Responsibilities

• Design, execute, and document manual test cases for firmware features across embedded Linux user space and kernel space.
• Validate wireless communication subsystems, including RF, WiFi, and Bluetooth, across multiple device configurations.
• Test and verify networking protocol behavior, including IPv4, IPv6, ICMP, DHCPv6, TCP/IP, UDP, PPP, and Ethernet, to ensure correct data transmission.
• Evaluate Layer-2 switching and routing functionality to confirm correctness, stability, and proper data flow.
• Focus on end-to-end data flow, verifying that data moves correctly from point A to point B, in the right format, on time, and through the appropriate routes in mesh networks.
• Test communication devices that use multi-layer (seven-layer) networking protocols, including devices such as gas and water meters and other RF or cellular-enabled endpoints.
• Perform system-level “box testing” of communication devices and firmware to validate overall functionality and robustness.
• Automate manual firmware test cases using scripting languages such as Python and Bash, or using Robot Framework, and integrate them into nightly regression builds and CI/CD pipelines.
• Build and configure hardware and software test setups from scratch, manually verify them, and then automate them for continuous regression coverage.
• Maintain and enhance the automation framework to ensure scalability, reliability, and coverage across all product lines.
• Identify, document, and track defects with clear reproduction steps, detailed logs, and thorough root-cause analysis.
• Monitor nightly build and regression results, triage failures, and report findings with actionable details and recommendations.
• Collaborate closely with firmware engineers to review requirements, provide early testing feedback, and improve testability and product design.
• Mentor junior QA engineers by sharing best practices in firmware testing, automation, and networking protocols.
• Use test management tools to organize, track, and report on test cases, test runs, and defects throughout the development lifecycle.
• Leverage network emulation and traffic analysis tools to analyze network behavior, troubleshoot issues, and validate protocol compliance.

Requirements

• Hands-on experience testing embedded Linux systems in both user space and kernel space.
• Proven experience testing wireless protocols such as RF, WiFi, or Bluetooth.
• Strong knowledge of networking protocols, including IPv4, IPv6, ICMP, DHCPv6, TCP/IP, UDP, Ethernet, and PPP.
• Familiarity with Layer-2 switching and routing protocol testing.
• Strong scripting skills in Python and/or Bash for test automation.
• Experience using Robot Framework for structured test automation.
• Experience integrating automated tests into CI/CD pipelines or nightly regression systems.
• Experience with Linux environments and networking protocols.
• Experience testing communication devices and mesh networks, with emphasis on data integrity, timing, routing, and format.
• Proficiency in C or C++ sufficient to understand and debug firmware-level code.
• Exposure to network emulation or traffic analysis tools such as Wireshark, iPerf, or tcpdump.
• Experience with test management tools such as TestRail, Jira, or equivalent systems.
• Experience with version control systems such as Git.
• Ability to work independently, manage multiple priorities, and deliver results with minimal supervision.
• Strong communication skills and a collaborative, ownership-driven attitude.

Qualifications

• Experience working with mesh networks and backbone communication systems that carry data between distributed devices.
• Experience in testing devices such as gas meters, water meters, or similar RF and cellular-based endpoints.
• Familiarity with real-time operating systems (RTOS) in addition to Linux.
• Experience with predominantly manual testing environments and transitioning manual tests to automation.
• Experience maintaining and extending automation frameworks for scalability across multiple product lines.
• Comfort working with seven-layer networking models and understanding interactions between different protocol layers.
• Experience mentoring junior engineers or contributing to team knowledge sharing.
