What is a contract Typescript developer?

A Contract Typescript Developer is a software professional who specializes in using the TypeScript programming language to build and maintain web and software applications on a contractual basis. Unlike full-time employees, contract developers are typically hired for specific projects or timeframes, providing flexibility for both the developer and the employer. TypeScript is a superset of JavaScript that adds static typing, which helps in catching errors early and improving code quality. These developers often work remotely or on-site, collaborating with teams to deliver high-quality code solutions. Their expertise is highly sought after for projects requiring scalable, maintainable, and robust applications.

What are the key skills and qualifications needed to thrive as a contract Typescript developer?

To thrive as a Contract Typescript Developer, you need a strong command of TypeScript, JavaScript, and web development fundamentals, often backed by a degree in computer science or relevant experience. Familiarity with frameworks like React or Angular, version control (Git), and experience with build tools and CI/CD systems are typically required. Excellent problem-solving, communication, and time management skills help developers stand out, especially in remote or fast-paced contract environments. These abilities ensure high-quality, maintainable code and seamless collaboration with diverse teams, which is vital for delivering successful projects on time.

What are some typical challenges a contract Typescript developer might face when joining a new project?

As a Contract Typescript Developer, you may encounter challenges such as quickly adapting to an existing codebase, aligning with the team's development standards, and understanding project-specific workflows. Since contract roles often require rapid onboarding, you might need to familiarize yourself with various tools, libraries, and deployment processes in a short timeframe. Additionally, effective communication with remote or cross-functional teams is essential to ensure smooth collaboration and timely delivery of tasks.

Contractor

Re-posted 9 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
