About Us:

 DMV IT Service LLC is a trusted IT consulting firm, established in 2020. We specialize in optimizing IT infrastructure, providing expert guidance, and supporting workforce needs with top-tier staffing services. Our expertise spans system administration, cybersecurity, networking, and IT operations. We empower our clients to achieve their technology goals with a client-focused approach that includes online training and job placements, fostering long-term IT success.

Job Purpose:

We are looking for a hands-on Test Automation Engineer to lead the advancement of frontend test automation across our Micro Frontend (MFE) React ecosystem. You will be embedded within a product engineering team and collaborate closely with developers, QEs, and SDETs to implement scalable, reliable, and developer-driven automated tests. This role plays a key part in transitioning from a traditional QA-led approach to a developer-owned, automation-first testing model focused on integration and user-centricity..

Key Responsibilities:

• Develop and manage end-to-end (E2E) and smoke test suites using Playwright to validate essential user interactions like browsing, shopping cart operations, and checkout processes.
• Write comprehensive integration tests using tools such as React Testing Library, Jest, and our internal testing utilities like @lululemon/mwa-testing.
• Establish and enforce testing structure and naming conventions to ensure clear traceability and easy analytics.
• Use Mock Service Worker (MSW) and shared test data tools to simulate APIs and manage test inputs dynamically.
• Translate manual test cases from platforms like TestRail into automated scripts, in collaboration with Quality Engineers.
• Lead conversations around the appropriate use of different test types—unit, component, integration, and end-to-end.
• Retire outdated Cypress tests and replace them with efficient, low-flake Playwright tests.
• Embed testing into GitLab CI/CD pipelines, integrating visual regression and test recording tools.
• Support continuous improvements by boosting coverage, reducing flaky tests, and encouraging early testing practices.

Required Skills & Experience:

• 3–5 years of professional experience in frontend testing or development.
• Strong skills in React, TypeScript, and working with Micro Frontend (MFE) environments.
• Hands-on experience writing E2E tests using Playwright or Cypress within CI/CD workflows.
• Proficient with testing tools like React Testing Library and Jest, as well as mocking APIs using MSW.
• Experience managing test configurations and results in GitLab CI/CD.
• Understanding of AWS tools related to test automation, such as S3 and CloudFront.
• Practical experience using test management software like TestRail.

Preferred Qualifications:

• Familiarity with tools like @testing-library/react-hooks, Storybook, and visual regression testing platforms.
• Previous experience migrating from Cypress to Playwright.
• Understanding of observability tools and techniques, including test reliability tracking and monitoring.
• Experience in agile development teams with DevOps responsibilities and collaborative coding practices.

Performance Indicators:

• Achieve over 90% integration test coverage for key features.
• Keep integration test execution times under 5 minutes.
• Maintain end-to-end test flakiness below 1%.
• Cut manual testing time for stories by at least 50%.
