Job description

Responsibilities

• Promote and evolve the software verification and validation (V&V) strategy for embedded products, including power meters, environmental monitors and controls, and edge gateways.
• Design, implement, and maintain manual and automated test coverage for embedded Linux software, firmware, and device‑level features.
• Develop and execute system‑level, integration, regression, and stress tests, including scenarios that mirror real‑world customer deployments (e.g., fully‑loaded devices, long‑duration uptime, and fault conditions).
• Collaborate with software and hardware engineers to review requirements, designs, and risks, ensuring testability and quality are built in early.
• Investigate field and manufacturing issues by reproducing failures, analyzing logs and network traffic, and performing root‑cause analysis.
• Contribute to test automation frameworks and CI pipelines to improve repeatability, coverage, and release confidence.
• Validate industrial and building‑automation communications protocols, as well as TCP/IP networks, and device‑to‑cloud interactions (MQTT).
• Define quality metrics and provide clear, data‑driven assessments of release readiness.

Requirements

• Bachelor’s degree in engineering or similar field and 5-10 years of related experience, or an equivalent combination of education and experience
• Demonstrated experience in software quality, test engineering, or verification roles, with a strong focus on embedded or systems‑level testing; typically, 6 years.
• Hands‑on experience testing embedded Linux systems and/or firmware‑driven devices.
• Strong understanding of networking fundamentals (TCP/IP) and experience validating device communications over wired and wireless networks.
• Experience testing industrial or building‑automation protocols (e.g., Modbus, BACnet, or similar).
• Proficiency with test automation and scripting, such as Python, shell scripting, or similar languages.
• Experience working with hardware‑integrated software systems, including interaction with sensors, meters, or I/O.
• Experience testing industrial / device UI’s, particularly with Squish
• Familiarity with CI/CD pipelines, version control systems (Git), and tracking tools like Jira and Zephyr.
• Ability to analyze logs, packet captures, and system behavior to isolate complex, cross‑disciplinary issues.
• Strong communication skills and the ability to work cross‑functionally with software, hardware, product, and manufacturing teams.
