• Experience supporting software development and quality engineering tools, including source control systems, defect tracking systems, test management platforms, and CI/CD environments.
• Experience with test automation frameworks and tools such as Selenium, or equivalent technologies used for desktop, web, or embedded software validation.
• Ability to evaluate software architectures, requirements, and technical deliverables across multiple software disciplines.
