Job Title:QA Automation Engineer
Location: Chicago, IL
Duration: 10 Months
Bill Rate: $77/hour (C2C)
Job Type: W-2, 1099, C2C
Client: To Be Discussed Later
Work Authorization: US Citizen, Green Card, OPT-EAD, CPT, H-1B, H4-EAD, Other

Job Description:

• Develop end-to-end UI automation suites covering critical business workflows, regression scenarios, and smoke tests across Chromium, Firefox, and WebKit.
• Write resilient locators using Playwright's role-based and test-id strategies, leveraging auto-waiting and web-first assertions to eliminate hard waits and reduce flakiness.
• Build reusable fixtures, custom commands, and test utilities; manage authentication state via storageState to avoid redundant login flows.
• Implement API test automation using Playwright's request fixture for service-layer validation and test data setup/teardown.
• Implement network interception and mocking (page.route) to isolate the UI from unstable downstream dependencies and to test error and edge-case states.

Required Qualification:

• Bachelor’s degree in computer science, Engineering, or related field.
• 3–6 years of hands-on test automation experience, including 2+ years with Playwright building and maintaining production automation frameworks.
• Demonstrated experience architecting automation frameworks from scratch — not just writing scripts in an existing one.
• Solid understanding of Playwright core concepts: locators, auto-waiting, fixtures, projects, parallelism, retries, tracing, and configuration.
• Proficiency with API testing — REST, JSON payloads, status code and schema validation (Playwright request, Postman, or REST Assured).
• Hands-on CI/CD integration experience with at least one of GitHub Actions, Jenkins, Azure DevOps, or GitLab CI.
• Strong Git skills — branching, pull requests, merge conflict resolution, code review participation.
• Working SQL knowledge for test data setup and backend validation.
• Solid grasp of QA fundamentals: test design techniques, boundary and equivalence analysis, risk-based testing, defect lifecycle.
• Experience working in Agile/Scrum teams with sprint-based delivery.
• Strong debugging and root cause analysis skills; ability to investigate failures across UI, API, and data layers.
• Clear written and verbal communication — able to explain quality risk to non-technical stakeholders.
