Quality strategy for reusable APIs and observability **Company Description** Serasa Experian is Brazil’s first and largest Datatech company.

With corporate headquarters in Dublin, Ireland, Experian is listed on the London Stock Exchange (EXPN) and is a constituent of the FTSE 100. **Job Description** The QA Engineering Specialist role owns the quality operating model for the organization, with the mandate to institutionalize the Quality Maturity Model (QMM), enforce quality within the delivery flow via quality gates in CI/CD (including authority to block deployments), and ensure safe reuse of Platform APIs (building blocks) by stream-aligned squads. What changes in the system (QMM + Gates + Building Blocks): QMM defines baseline, maturity levels, and a squad-specific roadmap. Quality gates transform quality standards into automated pipeline controls, reducing variation and regression risk (with authority to block releases when minimum criteria are unmet). Platform building blocks gain guaranteed quality via contract, compatibility, and non-regression, preventing multiple consumers from inheriting fragility. **Qualifications** **What we’re looking for in you:** * Leadership, communication, and problem-solving skills. * Experience with the Quality Maturity Model (QMM) * Development and Implementation of Quality Control Models: * Design and implement quality control models and tools. * Focus on adoption of continuous improvement policies and techniques. * Test Planning and Execution: * Plan testing strategies. * Develop test plans. * Create test scenarios. * Execute functional, performance, regression, and other types of tests. * Automated Testing Tools and Frameworks: * Proven experience in testing and quality assurance for IT solutions. * Rest assured, Cucumber, Cypress, JMeter, and Bruno for end-to-end (E2E) web application testing. * CI/CD Practices: GitHub Actions, GitLab CI/CD, or Jenkins — knowledge of continuous integration and delivery, configuring pipelines that include automated testing stages. **Your key deliverables will be:** * QMM (maturity): define baseline, build roadmap, and lead QMM adoption across squads, with objective checkpoints and risk-based evolution. * Quality gates (decision rights): design, implement, and operate gates in CI/CD, with clear minimum criteria, incremental evolution, and authority to block deployments when gates are not satisfied. * Building block quality: establish a quality strategy for reusable APIs (contracts, compatibility, regression, performance, versioning, and “consumer safety”). * Layered testing strategy: standardize BDD and scalable automation, balancing cost × risk × speed (contract/integration/regression/performance). * Observability and resilience: align quality practices with strong observability and degradation strategies, reducing detection and recovery time. * QA Chapter: lead the Chapter with pragmatic governance (playbooks, rituals, standards, and enablement), raising consistency and scale. * Coaching and mentoring: develop fellow QAs (and influence engineering) toward sustainable adoption of BDD, automation, and quality discipline. **Additional Information** Serasa Experian is much more than you imagine.
