Working closely with Tech Leads and Software Engineers, you will help ensure that software features behave according to agreed requirements and meet appropriate quality standards before being released to customers. Rather than relying solely on traditional manual testing, you will combine test automation, exploratory testing, risk-based testing, and AI-assisted testing to identify defects early and improve overall product quality. Developers are expected to perform initial testing of their own code, while QA Engineers provide an additional layer of quality assurance, particularly for high-risk changes, edge cases, and regression testing. You will also contribute to establishing modern testing practices that allow engineering teams to deliver software quickly without compromising reliability. The ideal candidate combines strong testing expertise, automation experience, analytical thinking, and a collaborative approach to software quality. Key Responsibilities Test Strategy & Quality Assurance Develop and maintain testing strategies for software development teams. Define which testing activities should be automated and which require manual or exploratory testing. Establish appropriate testing checkpoints before software releases. Collaborate with Tech Leads and Engineers to ensure software meets agreed requirements. Identify potential quality risks early in the development lifecycle. Help establish quality standards that support reliable and efficient software delivery. Test Automation & Regression Testing Design, develop, and maintain automated test frameworks. Implement automated testing using tools such as: Playwright Cypress Selenium Build and maintain regression test suites. Improve automated test coverage while ensuring tests remain meaningful and maintainable. Identify opportunities to reduce repetitive manual testing through automation. Collaborate with development teams to improve testing efficiency. Exploratory & Risk-Based Testing Perform exploratory testing for high-risk changes and complex functionality. Identify edge cases, unexpected behavior, and potential defects. Develop risk-based testing plans based on product requirements and technical changes. Investigate issues that may not be detected through automated testing. Provide an independent quality perspective to complement developer testing. Help prioritize testing activities based on business impact and technical risk. AI-Assisted Testing & Quality Engineering Use AI-assisted tools to support test case design and automated test code generation. Review and validate AI-generated test cases and test scripts. Identify defects, incorrect assumptions, and deviations from specifications in AI-generated outputs. Explore opportunities to improve testing productivity through AI-assisted workflows. Ensure AI-generated testing assets meet appropriate quality and reliability standards. Collaborate with engineering teams to establish effective AI-assisted testing practices. Test Environments & Data Management Collaborate with Engineering Managers and Software Engineers to prepare testing environments. Develop and maintain appropriate test data for functional and regression testing. Ensure testing environments support reliable and reproducible test execution. Identify issues related to test data quality and environment configuration. Support improvements to testing infrastructure and automation. Defect Management & Release Quality Investigate, document, and report software defects clearly. Create reproducible bug reports with appropriate technical details. Review acceptance criteria to ensure requirements are testable. Collaborate with developers to verify fixes and prevent regression issues. Evaluate whether releases meet agreed quality checkpoints. Recommend holding releases when critical quality requirements have not been satisfied. Support continuous improvement of defect prevention and release quality. Agile Collaboration & Continuous Improvement Work closely with Software Engineers, Tech Leads, Product Owners, and Engineering Managers. Participate in Agile development processes and quality-related discussions. Provide constructive feedback on requirements, implementation risks, and testing approaches. Promote a collaborative quality culture across engineering teams. Identify opportunities to improve testing processes, automation, and software reliability. Encourage continuous learning and adoption of modern quality engineering practices. Requirements Requirements Professional Experience 3+ years of professional experience designing and executing tests for web applications. Hands-on experience implementing and maintaining automated testing using tools such as Playwright, Cypress, Selenium, or similar frameworks. Experience with exploratory testing and risk-based test planning. Experience performing quality assurance within Agile software development teams. Ability to identify software defects, evaluate risks, and validate application behavior against requirements. AI-Assisted Testing Practical experience using AI-assisted tools for test design and automated test code generation. Ability to critically review and validate AI-generated test cases and test scripts. Experience identifying defects, incorrect assumptions, and specification deviations in AI-generated outputs. Understanding of how AI-assisted testing can improve productivity while maintaining software quality. Quality Engineering & Collaboration Strong analytical thinking and problem-solving skills. Attention to detail and commitment to software quality. Ability to communicate testing results and quality risks clearly. Collaborative approach to working with developers and other engineering stakeholders. Curiosity and willingness to explore new testing technologies and methodologies. Ability to provide constructive feedback and challenge unclear requirements when necessary. Preferred Qualifications Experience integrating automated tests into CI/CD pipelines. Experience with API testing, performance testing, or security testing. Relevant QA or software testing certifications such as JSTQB. Experience evaluating applications or features that integrate LLM technologies. Experience designing evaluation datasets for AI or LLM-powered functionality.
