[Job - 32574] Senior QA Engineer — AI-Driven Testing, Brazil

At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions.

With 30 years of experience in technological transformation, we accelerate innovation with expertise in Agentic SDLC, Application modernization, Data & AI, Martech and Business strategy.

We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.

We are hiring a Senior QA Engineer to support a healthcare insurance technology initiative. The project helps companies manage customer applications for underwriting, enrollment, eligibility, and policy-related workflows.

In this role, you will combine hands-on quality assurance with AI-driven test automation. You will work closely with developers and senior engineering leaders to ensure the application works correctly, validate complex business processes, and integrate AI testing tools into the team’s delivery workflow.

You should be self-sufficient, analytical, and comfortable testing different parts of an application — user interface (UI), APIs, data, and system integrations. You do not need experience with a specific testing tool; we will onboard you to the team’s existing AI-driven test suite.

What You Will Do

Analyze business requirements and technical specifications to create effective testing strategies

Create, maintain, and run test cases for functional, regression, integration, and end-to-end scenarios

Test application behavior across UI, API, data, and system integration layers

Design test scenarios for complex workflows (enrollment, eligibility, underwriting, and data exchanges)

Identify, document, track, and verify bugs in collaboration with developers and stakeholders

Support API testing, data validation, and integration testing across connected enterprise systems

Learn and use the team’s AI-driven test suite in day-to-day testing

Use AI-assisted testing practices to improve test design, coverage, and defect analysis

Set up and maintain automated regression testing in CI/CD pipelines

Collaborate with developers to ensure quality throughout the software development lifecycle

Document test results, bugs, risks, and quality status clearly

What You Need to Know

Professional experience in software QA or quality engineering (preferably at a senior level)

Demonstrated ability to work independently with limited supervision

Strong experience in test planning, test case design, execution, and bug management

Experience testing web applications, REST APIs, and system integrations

Understanding of functional, regression, integration, and end-to-end testing methods

Familiarity with test automation frameworks and automated regression suites

Experience validating data and working with SQL or relational databases

Familiarity with Agile delivery, Git (version control), and CI/CD concepts

Practical experience using AI tools responsibly in QA activities

Strong analytical, communication, and collaboration skills

Advanced English skills for both spoken and written communication.

Preferred Qualifications

Experience with AI-driven testing tools or AI-assisted test generation

Experience validating complex, data-intensive enterprise applications

Exposure to Salesforce, MuleSoft, IBM enterprise systems, or similar integration platforms

Experience in healthcare, insurance, enrollment, eligibility, or policy administration

Experience with automated testing in CI/CD pipelines and continuous quality practices

What Success Looks Like

Establishing reliable test coverage for critical application workflows and integrations

Identifying defects and risks early in the development lifecycle

Successfully learning and using the team’s AI-driven test suite in daily work

Improving regression testing efficiency and consistency

Providing clear visibility into application quality and readiness for release

Working effectively with developers and senior engineers to deliver stable, high-quality software
