Senior Web Automation QA Engineer / Senior SDET (Web Platforms)

As a Senior Web Automation QA Engineer/Senior SDET at the company, you will play a crucial role in ensuring the quality, reliability, scalability, and security of web-based platforms, portals, and APIs deployed on cloud infrastructure (AWS), Hybrid, and On-Prem Infrastructure. Your primary focus will be on automation-first testing, designing and maintaining robust web automation frameworks, validating complex end-to-end user journeys, and enabling fast, repeatable regression in CI/CD pipelines across cloud environments. Key Responsibilities: - Design and execute comprehensive functional, regression, integration, and negative tests for web applications hosted on AWS, Hybrid, and On-Prem platforms. - Validate end-to-end workflows spanning UI API backend services, including authentication/authorization, data integrity, and error handling in cloud environments. - Validate deployments across environments (DEV/QA/STAGE) hosted on various Infrastructure, including configuration and environment-specific behaviors. - Build and maintain code-based web automation using modern web automation frameworks such as Selenium/WebDriver, Playwright, or similar tools. - Implement maintainable automation patterns that withstand frequent UI changes and produce actionable test artifacts. - Produce actionable test artifacts (HTML/JUnit-style reports, screenshots, traces) and maintain evidence for all test scenarios. - Test and automate applications deployed on AWS infrastructure, Hybrid, and On-Prem Infrastructure, with an understanding of cloud-native and hybrid behaviors and dependencies. - Work with AWS services such as EC2, S3, RDS/Aurora, CloudWatch, IAM, and load balancers at a functional and testing level. - Validate application behavior during scaling events, configuration changes, and environment refreshes in the cloud. - Integrate automation into CI/CD pipelines executing against cloud-hosted, hybrid, or on-prem environments. - Partner with DevOps and developers to improve testability, observability, and pipeline stability in AWS environments. - Use GenAI/LLM tools to speed up test design, automation development, debugging, and documentation. - Critically evaluate AI output and follow enterprise AI governance practices. - Mentor engineers on automation best practices, cloud-aware test design, and coding standards. - Collaborate with Product, Engineering, QA, and DevOps teams to define automation and cloud test strategies. Required Qualifications: - 6+ years of QA experience with specialization in web testing and automation. - Hands-on experience with Selenium/WebDriver, Playwright, or similar web automation frameworks. - Strong programming skills in languages commonly used for automation. - Experience testing applications deployed on AWS or other cloud platforms. - Strong understanding of REST APIs, JSON, authentication/authorization, and cloud-based application debugging. - Experience integrating automated tests into CI/CD pipelines. - Experience using GenAI/LLM assistants. - Proficiency with Git-based workflows and Agile/Scrum development practices.
