Analista de QA - Sênior

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Analista de QA - Sênior in Brazil.

This role is focused on driving quality engineering excellence across modern full-stack applications, ensuring robust, scalable, and reliable software delivery. You will play a key role in defining and implementing automated testing strategies across multiple layers, including unit, integration, API, and end-to-end testing. Working closely with development teams, you will contribute to a clean architecture environment where quality is embedded from design to deployment. The position combines technical depth in automation frameworks with a strong mindset for continuous improvement and proactive quality ownership. You will work with technologies such as C#, .NET, Playwright, React, and Azure DevOps in a highly collaborative engineering culture. This is a hands-on and strategic QA role where your work directly impacts product stability, performance, and user experience.

You will be responsible for ensuring software quality through the design, implementation, and evolution of automated testing strategies across backend, frontend, and API layers in a modern engineering environment.

• Design and implement a comprehensive test strategy aligned with the test pyramid (unit, integration, and E2E).
• Develop backend automated tests in C# .NET using xUnit, validating business logic, handlers, repositories, and domain layers.
• Create and maintain E2E tests using Playwright to validate user flows in React-based applications.
• Implement and execute API testing, including validation of REST endpoints, JSON schemas, authentication flows, and JWT handling.
• Manage test data setup and cleanup processes in PostgreSQL environments.
• Debug and analyze test failures using logs, traces, and observability tools to identify root causes.
• Execute and maintain test pipelines within Azure DevOps CI/CD environments.
• Contribute to quality improvements by identifying gaps in coverage and proposing automation and process enhancements.

Requirements:

The ideal candidate has strong experience in quality engineering with full-stack testing capabilities, combining backend, frontend, API, and DevOps knowledge in a structured engineering environment.

• Solid experience with C# .NET and understanding of backend architecture (Clean Architecture, CQRS).
• Strong expertise in xUnit for backend testing and SQL (PostgreSQL) for test data management.
• Hands-on experience with Playwright for E2E testing (TypeScript) and understanding of React fundamentals.
• Strong knowledge of REST API testing, including status codes, JSON validation, and authentication (JWT).
• Experience with CI/CD pipelines using Azure DevOps and Git workflows.
• Understanding of test pyramid principles and modern QA engineering practices.
• Ability to debug complex issues using logs, traces, and system analysis tools.
• Proficiency in Linux/CLI environments for test execution and troubleshooting.
• Strong analytical thinking, attention to detail, and proactive mindset for improving QA processes.

Benefits:

• Competitive compensation package aligned with market standards
• Remote-friendly work model
• Health and dental insurance
• Meal or food allowance (depending on work arrangement)
• Career development and continuous learning opportunities
• Access to modern engineering tools and automation frameworks
• Collaborative and innovation-driven engineering culture
• Participation in impactful, large-scale software projects
