This role sits at the system level-where real-world device behavior meets software quality-and ensures our platforms are robust, reliable, and ready for production and field use. You'll own system-level validation across hardware, firmware, backend services, and web interfaces, working closely with product, firmware, software, and manufacturing teams. Typical tasks of the position include, but are not limited to What You'll Do System-Level Testing & Validation * Design and execute system-level test strategies for Linux-based IoT and connected instrument platforms * Validate end-to-end workflows across device firmware, edge services, backend APIs, and web UI * Perform functional, integration, regression, performance, and reliability testing * Test system behavior under real-world conditions (network latency, device failures, power cycling, upgrades, stress scenarios) Hardware-Software Integration * Test instrument bring-up, initialization, calibration, and recovery across firmware updates and fault conditions * Validate operation under environmental and operational stress (temperature, vibration, long-duration runs) * Lead and support cross-disciplinary root cause analysis involving software, firmware, electronics, and mechanical subsystems * Use logs, telemetry, and lab tools (e.g., multimeter, oscilloscope, logic analyzer) to diagnose complex system issues Automation & CI/CD (System Focus) * Develop and maintain automated tests at the system, API, and web layers (Python preferred) * Integrate automated tests into CI/CD pipelines to support continuous quality and release readiness * Collaborate with DevOps and development teams on build verification, deployment validation, and pre-production testing Manufacturing & Field Support (Collaboration-Oriented) * Support manufacturing and service teams by validating system-level test coverage and diagnostics * Reproduce field and manufacturing issues in lab environments and help drive corrective actions The successful candidate will have a combination of knowledge, skills, and experience that would include the following ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Continuous testing - run automated tests for every change!](https://www.wearedevelopers.com/videos/190-continuous-testing-run-automated-tests-for-every-change) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The Best Software Developer Blogs to Read](https://www.wearedevelopers.com/magazine/156-the-best-software-developer-blogs-to-read) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 119 - ❤️ === ❤️](https://www.wearedevelopers.com/magazine/454-dev-digest-119) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries)
