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., * 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. ## Related Videos - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) - [Continuous testing - run automated tests for every change!](https://www.wearedevelopers.com/videos/190-continuous-testing-run-automated-tests-for-every-change) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss)
