Overview In this Lead Quality Engineer role, you will architect and guide the QE function during a critical transformation: monolith-to-microservices, Playwright consolidation, and AI-generated code at scale. You'll define quality gates, automate testing infrastructure, and build shared tooling that makes high-quality testing the default for all engineering teams. You'll coach engineers, drive flakiness reduction, and shape an AI-first approach to testing that scales with the business. This is a hands-on leadership role with architectural authority and a clear impact on Duetto's testing practice.
