Job Description/Preferred Qualifications

Job Responsibilities

Test Automation Engineer

• Understand the system and customer workflows end-to-end by analyzing product requirements, architecture, and real customer use cases; translate these into automation strategy and test coverage for web applications and web services.
• Participate early in the SDLC by reviewing functional/system requirements and designs to ensure testability, identify risks, and define measurable acceptance criteria aligned with user journeys and service/API contracts.
• Build and maintain a scalable test automation framework using Playwright (web UI automation) with strong engineering practices (reusable utilities, page/component patterns, stable selectors, test data strategy, reporting).
• Automate critical user flows (smoke, regression, and high-risk business paths) by modeling realistic user behavior and validating the complete workflow 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 true end-to-end quality coverage.
• Apply AI-assisted automation practices to improve reliability and maintenance efficiency (e.g., smarter test generation, adaptive/self-healing approaches, and AI-enabled test execution where applicable) to reduce script fragility and speed up automation development.
• Create and maintain test plans, automation suites, and execution pipelines to run on-demand and on schedule; ensure results are observable via dashboards/logs/reports and are usable for release decisions.
• Execute and monitor automated test runs across builds; analyze failures to distinguish product defects vs. test issues, improve stability, and keep the automation suite production-grade.
• Measure and communicate automation coverage, ROI, quality trends, and release risk; continuously prioritize automation work based on defect trends and usage-critical paths.
• Collaborate with cross-functional and global stakeholders (developers, architects, product owners, system engineers) to improve testability and promote quality best practices throughout the lifecycle.

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 a good understanding of 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.
