Job Responsibilities: Test Automation Engineer

• Understand system and customer workflows by analyzing product requirements, architecture, and customer use cases, translating them into automation strategies for web applications and web services.
• Participate early in the SDLC by reviewing requirements and designs to ensure testability, identify risks, and define acceptance criteria aligned with user journeys and service/API contracts.
• Build and maintain a scalable test automation framework using Playwright for web UI automation, adhering to strong engineering practices like reusable utilities, page/component patterns, stable selectors, test data strategy, and reporting.
• Automate critical user flows (smoke, regression, high-risk business paths) by modeling realistic user behavior and validating complete workflows across UI, backend services, and data stores.
• Develop automated validations for Web Services/APIs (service-level functional checks, contract validation, negative testing, error handling) and integrate them with UI flows for comprehensive end-to-end quality coverage.
• Apply AI-assisted automation practices for improved reliability and maintenance efficiency, such as smarter test generation, adaptive/self-healing approaches, and AI-enabled test execution.
• Create and maintain test plans, automation suites, and execution pipelines for on-demand and scheduled runs; ensure results are observable via dashboards/logs/reports for release decisions.
• Execute and monitor automated test runs, analyze failures to distinguish product defects from test issues, and improve stability.
• Measure and communicate automation coverage, ROI, quality trends, and release risk; prioritize automation work based on defect trends and critical paths.
• Collaborate with cross-functional and global stakeholders (developers, architects, product owners, system engineers) to improve testability and promote quality best practices.

Job Requirements

• Bachelor's degree or higher in Computer Science, Computer Applications, Software Engineering, Automation, Electronic Engineering, or a related technical field.
• Familiarity with software quality control processes and web UI testing concepts.
• Proficiency in at least one programming or scripting language such as C/C++, Python, Perl, or VBScript.
• Experience with Visual Studio, automated testing frameworks, MySQL or Oracle databases, and Linux commands is preferred.
• Fluent in spoken and written English.
• Strong initiative, fast learning ability, proactive attitude, and excellent team spirit.
