• Document and track defects in JIRA with clear reproduction steps and severity classification
• Participate in sprint ceremonies and collaborate with developers on acceptance criteria

Automated Testing (50%)

• Design, develop, and maintain automated test scripts using TypeScript and Python
• Build integration tests for APIs, cloud services, and IoT device communication protocols
• Create regression test suites to ensure existing functionality remains stable across releases
• Integrate automated tests into AWS CodePipeline for continuous testing
• Expand test coverage across critical user flows and system integrations
• Monitor test execution results and triage failures
• Optimize test execution time and reliability

Process Improvement

• Enhance and mature existing QA processes, standards, and best practices
• Identify gaps in test coverage and recommend improvements
• Contribute to building a more robust testing framework
• Collaborate with the cloud development team to shift quality left in the development lifecycle

Required Qualifications

• 3-5 years of experience in software quality assurance or testing roles
• Strong foundation in both manual and automated testing methodologies
• Hands-on experience writing automated tests in TypeScript and/or Python
• Solid understanding of integration testing, especially for APIs and distributed systems
• Experience testing software applications and REST APIs
• Familiarity with CI/CD pipelines and automated test integration
• Proficiency with bug tracking and test management tools (JIRA experience preferred)
• Strong analytical and problem-solving skills with attention to detail
• Ability to work independently and manage testing tasks throughout the sprint cycle
• Excellent written and verbal communication skills for documenting defects and collaborating with developers
• Experience working in Agile/Scrum environments

Preferred Qualifications

• Experience testing IoT devices, hardware, or embedded systems
• Knowledge of cloud platforms, particularly AWS services
• Familiarity with AWS CodePipeline or similar CI/CD tools
• Experience with API testing tools (Postman, REST Assured, etc.)
