Experteer 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.

Compensaciones / Ventajas
• Design quality gate logic in GitHub Actions pipelines, including coverage thresholds, mutation gates, contract tests, flaky test quarantine, and automated result reporting.
• Build DataDog dashboards to monitor test health, coverage trends, and flaky rates across the organization.
• Lead migration from Selenium and Cypress to a consolidated Playwright framework; own shared configuration, CI sharding, and page object library design.
• Drive PR pipeline test execution toward a 15-minute target by reducing flakiness and optimizing pipelines.
• Design and implement Pact contract testing for monolith-to-microservices boundaries, manage the Pact broker,



and standardize consumer-driven contract testing.
• Design and maintain Testcontainers configurations for MongoDB, PostgreSQL, Redis, LocalStack, and RabbitMQ to support reliable integration tests.
• Champion AI-augmented testing practices using Claude Code, CodeRabbit, and Augment; evaluate AI-generated test code for correctness and coverage.
• Mentor developers on testing practices, automation patterns, and mutation testing (PIT, Stryker) within a hybrid guild model.

Responsabilidades
• 6+ years in software quality engineering or test automation in a production SaaS environment.
• Strong hands-on Playwright experience for end-to-end testing with CI integration.
• Proven ability to define and implement quality gates in GitHub Actions.
• Contract testing experience, with Pact strongly preferred.
• Proficiency in Java and TypeScript/JavaScript for test implementation.
• Experience with Testcontainers or equivalent integration test infrastructure.
• Track record reducing flaky tests in distributed service-oriented architectures.
• Active experience with AI coding assistants for test generation and automation; ability to validate AI-generated output.
