• Troubleshoot and optimise pipeline performance, stability, and observability

• Partner with Infrastructure, Operations, and Security teams to maintain hardened, compliant environments for CII systems

• Develop and maintain automated tests for CII-related applications, processes, and system behaviours

• Automate scenarios including API interactions, high-availability flows, transaction validation, data validation, batch processing, and system failover behaviour

• Build regression, functional, and end-to-end automated test suites aligned to CII resiliency and compliance requirements

• Integrate CII-related automated tests into CI/CD pipelines for continuous quality gates

• Maintain test data frameworks, reusable automation modules, environment configurations, and robust execution artefacts

• Create reusable script libraries, validation logic, and data-driven testing utilities

• Analyse failures, identify root causes, and improve automation architecture and system testability

• Work with Developers, Business Analysts, and Quality Engineers to refine user stories, acceptance criteria, and test coverage plans
