Temp Wifi Test Engineer Jobs (NOW HIRING)

Job Title: Firmware Test Engineer

Job Description

The Firmware Test Engineer designs, executes, and automates tests for embedded Linux firmware and wireless communication devices, ensuring reliable data transmission across complex mesh networks. This role focuses on validating networking protocols, wireless subsystems, and backbone communication paths that carry critical data for devices such as gas and water meters. The engineer builds and maintains test environments, contributes to continuous integration and regression testing, and collaborates closely with firmware and QA teams to improve product quality and test coverage.

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.
• Work independently to manage multiple testing priorities and deliver high-quality results with minimal guidance.

Essential Skills

• 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.
• Working 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.

Additional Skills & 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.
