• Own test strategy & automation: design, implement, and maintain tests (unit, API/component, end-to-end) for new and existing features. • Shift left: collaborate with devs and PMs early in design to prevent defects; add checks to CI/CD and merge gates. • Data & tooling: build/maintain scripted tooling and fixtures for reliable, repeatable test data. • Systems testing: validate end-to-end scenarios across Linux, containers, and public clouds (AWS/Azure/GCP); verify networking and identity flows. • Quality operations: triage, track, and drive defects to resolution in Jira (or similar); report meaningful quality metrics. • Environments: configure and manage test environments for stability and performance; bake in observability for fast failure triage. • Continuously improve: expand coverage, reduce flake, and streamline the pipeline.
