Full Description

Testing & Automation Engineer

About The Role

The Testing & Automation Engineer designs, develops, and maintains automated test solutions that ensure the quality and reliability of software applications and services, operating as part of the enterprise-wide Testing function — a horizontal shared service supporting all product, platform, and engineering teams. This role increases functional test coverage through automation, reduces manual effort, and supports consistent, high-quality delivery across the software development lifecycle in accelerated, AI-assisted cycles. The Testing & Automation Engineer partners closely with Software Engineers, Product, and DevOps teams to embed quality early and continuously.

Responsibilities Include But Not Limited To

Design, develop, and maintain automated tests for UI, API, and backend services; execute functional, integration, regression, and end-to-end tests across applications and platforms, applying a test-pyramid approach that favors fast, reliable API/service-level automation. Partner with Software Engineers and Product teams to define test scenarios and acceptance criteria; participate in sprint planning, refinement, and retrospectives. Maintain and enhance test-automation frameworks and tooling; build resilient, maintainable automation (e.g., attribute/accessibility-based locators) that survives UI and content change; integrate automated tests into CI/CD pipelines (e.g., Azure DevOps) for continuous testing. Identify, document, and track defects through resolution; perform root-cause analysis and partner with engineering teams on fixes. Define and apply functional-quality release-readiness criteria; provide evidence-based quality signals and go/no-go input for releases, and report coverage and defect-escape measures. Leverage AI-assisted tools across the test lifecycle (test-case generation, test-data creation, coverage analysis, defect detection); review and validate AI-generated tests, tag and report AI-generated test cases for transparency, and help define guardrails for safe, policy-compliant AI use.

Qualifications (some Examples Listed Below)

5–7+ years of experience in software testing, quality engineering, or automation roles. Proficiency with automation tools and frameworks (e.g., Selenium, Cypress, Playwright, REST-assured, Postman, or similar). Ability to read, write, or debug test code or scripts (e.g., Java, JavaScript/TypeScript, Python, C#). Understanding of REST APIs and service-based architectures; familiarity with CI/CD pipelines and continuous-testing concepts. Hands-on experience with AI-assisted testing tools and practices required. Familiarity with observability concepts and using quality/monitoring signals to inform testing is a plus. Bachelor’s degree preferred in Computer Science, Engineering, Information Systems, or a related field. Equivalent practical experience considered.
