QA Engineer (AI & Feature Testing)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a QA Engineer (AI & Feature Testing) based in Brazil.
Join a technology-driven team developing and validating innovative features for a leading personal finance platform, combining traditional software testing with next-generation AI quality assurance. As a QA Engineer, you will take ownership of quality across web applications, mobile platforms, and APIs, ensuring reliable, secure, and seamless user experiences. You will play a key role in testing AI-powered features, including large language model (LLM) integrations, where outputs can be probabilistic rather than strictly predictable. By combining deterministic testing techniques with AI evaluation methodologies, you will help identify inaccuracies, hallucinations, edge cases, and potential safety risks before they affect users. Working closely with engineers, product stakeholders, and international teams, you will contribute to robust testing strategies and continuously improve quality standards. This role offers an opportunity to apply your hands-on testing expertise to emerging AI technologies while promoting responsible AI development and dependable software delivery. If you are a detail-oriented QA professional who enjoys solving complex problems and exploring the evolving intersection of software quality and artificial intelligence, this opportunity offers meaningful technical challenges and room for growth.
