• Audit the current state of test coverage and CI pipelines across the OpenCTI, OpenAEV, and OpenGRC — identify critical gaps and define a prioritised roadmap to address them. • Define and implement a cross-product test strategy covering unit, integration, end-to-end, and contract testing — adapted to each layer of the stack (GraphQL API, TypeScript/React frontend, Node.js/Java backend, Python connectors). • Lead the consolidation and standardisation of CI/CD pipelines towards GitHub Actions, introducing quality gates (coverage thresholds, mutation testing, flakiness detection, static analysis) as first-class pipeline steps. • Build shared test tooling, templates, and libraries that product teams can adopt with minimal friction — reducing the cost of writing good tests. • Introduce and maintain performance and load testing practices where none currently exist, establishing baselines and regression detection for critical system paths. • Define and enforce standards for test reliability and pipeline speed — flaky tests and slow pipelines are engineering debt you'll actively reduce. • Work closely with product engineering teams to embed quality practices in their day-to-day workflows, providing guidance, code reviews, and hands-on pairing where needed. • Stay current with the testing, CI/CD, and AI-assisted engineering landscape — evaluating new tools, LLM-based test generation approaches, and agentic testing frameworks, and bringing well-reasoned proposals to the team.
