What does a React developer do?

As a React developer, you work in a comprehensive JavaScript library known as React. Your responsibilities are to design, develop, and implement this front-end technology for businesses.

Contractor

Re-posted 24 days ago

Job description

Role:  Software Developer in Test (SDET)

Location:  Seattle, WA

Job Type: Contract

Job Description:

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 @lululemon/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.

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
