• Elaborar planos de testes com base em requisitos de software e especificações; • Criar casos e evidências de testes, relatar resultados, avaliar a qualidade técnica e funcional dos produtos, identificar riscos e possíveis falhas relacionadas aos códigos e funcionalidades entregues; • Realizar testes funcionais, de desempenho, de segurança e outros tipos de testes para identificar defeitos e problemas de software. Isso pode envolver testes manuais e/ou automatizados; • Trabalhar em conjunto com a equipe para garantir a entrega do software conforme o planejamento realizado; • Gerar e manter a documentação dos testes do sistema conforme o Processo de Testes da Contratante.

• Thoroughly testing developed web applications against specified requirements across a variety of desktop browsers and mobile devices, ensuring cross-platform compatibility and a seamless user experience regardless of environment. • Apply, and further develop, a grounding in test automation by learning and using low‑code and no‑code UI‑based tools as part of your testing responsibilities. • Diligently recording and monitoring issues to ensure clarity and resolution, maintaining clear communication channels with development teams and stakeholders to expedite troubleshooting and fixes. • Creating and maintaining comprehensive test documentation as needed, including test plans, test cases, and test scripts, to support repeatability and knowledge sharing within the team. • Collaborating closely with developers and stakeholders to effectively resolve issues, providing critical feedback, and participating in defect triage meetings to prioritize problems based on impact and urgency. • Consistently tracking test progress in alignment with release schedules, while prioritizing workloads efficiently to meet deadlines without compromising on quality or thoroughness. • Reviewing test environments and processes to drive continuous improvements and uphold high-quality standards, actively suggesting enhancements to test strategies and tools that align with evolving project requirements. • Supporting the team by providing accurate estimates for testing efforts, contributing to realistic project planning and resource allocation to ensure timely delivery of high-quality software products.

• Ensure the resilience, stability, and technical quality of the company's highly complex products. • Work cross-functionally with squads, establishing standards of excellence in software engineering. • Ensure the accuracy and reliability of Artificial Intelligence models in production. • Ensure zero-failure operation of the payments engine, with a focus on security, availability, and transactional consistency. • Validate the integrity and consistency of the real‑time messaging system used by agents. • Review, validate, and ensure that each code delivery meets the quality, performance, and scalability criteria required for a world-class product. • Define, disseminate, and evolve best practices for architecture, testing, observability, and technical governance.

• Own our CI/CD systems end-to-end: audit the current state, redesign where needed, and drive measurable improvements in pipeline reliability, build/test cycle time, and overall developer experience within the first six months • Lead the adoption of standardized QE practices and testing frameworks across engineering teams, reducing inconsistency in coverage and establishing a shared standard for quality across the organization within your first year • Drive increased automation of QE processes using AI-assisted tooling (such as Claude, Codex, or Cursor), accelerating development velocity while maintaining rigorous standards • Lead, mentor, and grow a team of 1–3 Quality Engineers: supporting their technical development, career growth, and day-to-day effectiveness, with a goal of visibly improving team velocity and reducing defect escape rates • Partner closely with Engineering and Product to shift quality earlier in the development lifecycle, building a culture where defect prevention is prioritized over defect detection • Establish structured knowledge sharing and process documentation that enables the team to scale its impact beyond its headcount
