Senior Systems QA Engineer

Role Overview

Validate the integration and performance of end-to-end physical access systems spanning authentication credentials and services, authentication devices, access-control hardware and system-management platforms. Work in a hands-on lab-first Systems QA team supporting UX validation, shared test environments and automation setups.

Duties and Responsibilities

• Integrate system components and report on performance, stability and user experience.
• Maintain and evolve a Systems and Solution lab for continuous operation, including new products and upgrades.
• Research, plan and execute system-level test plans and test runs for performance and non-functional requirements.
• Design test solutions that consider how individual components integrate into the full system.
• Define test-entry criteria and real-world use cases for UX validation.
• Collaborate with stakeholders to define objectives and validation strategies.
• Review programme plans, specifications, defect reports and requirements.
• Run baseline exercises and analyse performance, reliability and test data.
• Support defect triage and produce clear test reports.
• Ensure test samples and equipment are available.
• Perform manual and automated testing, including automation tools and Hardware-in-the-Loop setups.
• Contribute to system-level, interoperability, stress and reliability testing.
• Participate in Agile or SAFe ceremonies and cross-functional issue resolution.
• Support physical access-control system roadmap initiatives.
• Work in lab and office environments, with occasional travel and fieldwork.

Experience and Technology

• Bachelor's degree in Computer Science, Electronic Engineering, Computer Engineering or equivalent.
• Five to seven years' software-testing experience focused on UX or UAT validation.
• ISTQB CTFL or equivalent certification is desirable.
• SAFe, Scrum, Kanban or similar Agile experience is desirable.
• Experience with UX and UAT for mobile applications integrated with physical products.
• System-level testing across hardware, firmware, mobile applications and cloud platforms.
• Hands-on experience with automation frameworks, embedded development and C#, Python, C, C++, XAML, NodeJS or similar.
• Experience with Appium, Selenium, API testing, defect tracking, test-management and code-repository tools.
• Experience with application-development environments such as .NET, Visual Studio, Arduino IDE and VS Code.
• Experience with data analytics and visualisation tools such as Oracle Analytics, Grafana and Mixpanel.
• Experience with macOS, Android, iOS and Linux.
