Overview

We are seeking a freelancer to support QA needs on a very exciting new project with a major client. As a  Mid-Level Quality Engineer, you will be responsible for improving the quality and reliability of our software applications through meticulous functional testing techniques. Your primary focus will be to identify and define testing scenarios, verify application readiness and report defects, test bug fixes, and contribute to improving our products and processes. Specific projects may need automation skills at either UI or API layers.

Type of engagement: Freelancer

Status: Approximately 40 hours/week

Project duration: 6+ months, depending on project

Location: LatAm

Responsibilities & Expectations 

• Functional Testing: Conduct thorough functional testing of our software applications to verify they meet the specified requirements and deliver a flawless user experience.
• Test Case development and maintenance: Create comprehensive and well-structured test cases based on functional specifications, design and requirements documents. Maintain accurate testing documentation, including test plans, test cases, and test data case management tools (Testmo for instance).
• Test Execution: Execute test cases to verify the functionality, usability, and reliability of software products. Check application readiness across different platforms and devices. Execute UI or API automated tests and evaluate its results. Inform stakeholders about testing results. Testing experience with cross browser tools like BrowserStack. 
• Define testing plans depending on the application release, environment and features to be included with test data definition.
• Defect identification, reporting and tracking: Identify and accurately document software defects and issues, including steps to reproduce, and report them in a clear and concise manner. Perform root cause analysis of identified issues. Monitor and manage defects throughout the testing lifecycle.
  Define defects priority and severity accordingly. 
• Regression Testing: Conduct regression testing to ensure that previously identified issues have been resolved and that new changes do not introduce new defects.
• Ability to operate autonomously in the definition and execution of testing plans along with any found issues identified.
• Collaboration and team player: Collaborate with developers, product managers, clients, and other cross-functional teams to ensure effective communication and prompt resolution of issues. Document and share best practices and lessons learned with the rest of the team.
• Continuous Improvement: Contribute to the improvement of testing processes, methodologies, and best practices to enhance overall product quality.
• Mobile UI Automation and CI/CD Integration: Design, develop, and maintain automated UI tests for mobile applications on iOS and Android, using frameworks such as Maestro, Appium, Patrol, or Flutter integration tests. Integrate automated suites into CI/CD pipelines (GitHub Actions, Bitrise, Codemagic, or similar) so they run on every pull request, nightly build, or release candidate, against emulators, simulators, and real device clouds like BrowserStack. Monitor pipeline results, triage failures, reduce flakiness, and turn automation feedback into actionable insights so the team can ship with confidence and speed.
• AI-Assisted Quality Engineering: Use AI tools such as Claude Code, Cursor, or GitHub Copilot as part of the daily testing workflow to speed up test design, test case generation, automation scripting, and defect analysis. Build, maintain, and share reusable AI skills and agent workflows (for example, skills that verify Jira acceptance criteria, generate Maestro flows from app exploration, or triage incoming bug reports).

Qualifications:

• At least 3 years of experience as Quality Engineer.
• Functional Testing Expertise: Strong knowledge and hands-on experience with functional testing techniques, including test case design, test execution, defect reporting, and regression testing.
• Analytical Thinking: Demonstrated ability to think critically and analyze complex scenarios to design effective test cases.
• Ability to plan and operate independently.
• Attention to detail: Meticulous and thorough in verifying application behavior and ensuring the accuracy and completeness of test cases and documentation.
• Problem-Solving Skills: Proven problem-solving skills to troubleshoot issues, investigate defects, and propose solutions.
• Team Player: Ability to work collaboratively in a team-oriented environment and willingness to share knowledge and learn from others.
• Adaptability: Flexibility to quickly adapt to changing project requirements and priorities.
• Testing Tools: Proven ability with testing tools and software, such as bug tracking systems and test case management tools. Familiarity with UI and API automated testing frameworks.
• Mobile Automation and CI/CD: Hands-on experience building and maintaining mobile UI automation for iOS and Android, and integrating automated test suites into CI/CD pipelines, including test reporting and failure analysis.
• AI Tooling: Practical experience using AI assistants and agents in QA work, including creating or customizing skills, prompts, or MCP-based workflows, along with the judgment to validate AI-generated results.
• Excellent verbal and written communication skills in English to effectively communicate with team members, clients and stakeholders.
