Job Description

Job Role: Sr. SDET

Location: Seattle, WA - locals only - hybrid model

Pay Rate: $60-$65/hr. on C2C/1099

MUST HAVE: Playwright, React, Typescript and E2E.

We are seeking a hands-on Test Automation Engineer to drive the next evolution of frontend test coverage across our Micro Frontend (MFE) React ecosystem. You’ll be embedded in a product engineering team, working in close partnership with developers, QEs, and SDETs to deliver scalable, reliable, and developer-owned automated testing aligned with our testing trophy strategy.

This role is part of a strategic shift from a QA-led to a developer-owned testing model, emphasizing integration-first, user-centric, and automation-first practices.

Key Responsibilities

• Build and maintain Playwright-based E2E and smoke tests for critical guest journeys (e.g., browse, add-to-bag, checkout).
• Develop robust integration tests using React Testing Library, Jest, and our internal @---/mwa-testing harness.
• Drive test colocation and naming conventions to support auditability, execution traceability, and analytics.
• Use Mock Service Worker (MSW) and shared data fakers for API mocking and dynamic data setup.
• Ensure tests are aligned with TestRail test cases, partnering with QEs to translate manual test intent into code.
• Contribute to test strategy discussions: define when and how to use unit, component, integration, or E2E tests.
• Help sunset low-value Cypress tests and replace them with performant, reliable tests.
• Integrate tests into GitLab CI/CD, including trace/video capture and visual regression workflows.
• Collaborate with developers and QE to increase test coverage, reduce test flakiness, and shift left testing practices.

What You Bring

Must-Have Skills:

• 3–5 years frontend testing or development experience
• Strong proficiency with React, TypeScript, and MFE architecture
• Experience with Cypress or Playwright for E2E testing in CI/CD environments
• Solid understanding of React Testing Library, Jest, and mocking frameworks like MSW
• GitLab CI/CD experience, especially in configuring test jobs and managing test artifacts
• Familiarity with AWS services relevant to frontend pipelines or test artifact storage (e.g., S3, CloudFront)
• Working knowledge of TestRail or other test case management platforms

Nice-to-Have:

• Experience with @testing-library/react-hooks, Storybook, or Visual Regression Testing
• Prior exposure to Cypress, with the ability to help decommission and port to Playwright
• Awareness of observability practices (e.g., logging, monitoring, flakiness tracking)
• Comfort working in agile product teams with shared code ownership and DevOps practices

Success Metrics

• 90%+ integration coverage on critical flows
• <5 minute integration suite runtime
• <1% flakiness on E2E Playwright suite
• 50%+ reduction in manual story testing time
