Senior Automation QA Engineer (Playwright/Typescript)

Accountabilities:: Design, develop, maintain, and stabilize automated end-to-end (E2E) and API tests using TypeScript and Playwright. Lead the migration of legacy automated tests from Java and Selenide to a modern Playwright and TypeScript-based testing framework. Build and continuously improve test automation architecture, including fixtures, browser contexts, test data management, state handling, and parallel execution capabilities. Develop and optimize load-testing scenarios using k6, collaborating with software developers to analyze system performance and identify bottlenecks. Evaluate performance metrics, investigate scalability limitations, and recommend improvements to enhance application responsiveness and reliability. Apply appropriate test design techniques and testing strategies to ensure meaningful coverage across UI, API, and performance testing layers. Write clean, maintainable, reliable, and concurrency-safe code that supports stable automated test execution. Conduct code reviews, share technical knowledge, and promote consistent engineering and quality assurance standards across the team. Collaborate closely with product teams, developers, and other QA engineers to integrate quality practices throughout the software development lifecycle. Contribute to continuous integration and delivery processes by improving automated testing workflows and integrating test suites into CI/CD pipelines. Explore modern tools, including AI-powered coding assistants, to streamline testing activities and reduce repetitive tasks. Requirements: At least five years of professional experience in software quality assurance, test automation, or a related engineering role. Strong proficiency in TypeScript, including interfaces, generics, asynchronous programming, and async/await patterns. Hands-on experience building and evolving Playwright automation frameworks from the ground up, including fixtures, browser contexts, test state and data management, and test stability. Proven experience automating UI workflows through E2E testing and validating REST APIs, with a solid understanding of what to test at each level. Strong knowledge of test design techniques, testing methodologies, coverage assessment, and risk-based test prioritization. Practical experience with load and performance testing, including workload modeling, performance metrics, bottleneck identification, and results analysis. Experience with tools such as JMeter, Gatling, or Locust is relevant; familiarity with k6 is particularly valuable. Ability to write clean, maintainable, and reliable automation code that supports parallel execution and minimizes flaky tests. Strong analytical and problem-solving skills, attention to detail, and the ability to investigate complex technical issues. Effective communication and collaboration skills, with a proactive approach to knowledge sharing, constructive feedback, and cross-functional teamwork. Familiarity with Java, Maven, and Selenide is an advantage, particularly when working with legacy automation suites. Experience with CI/CD platforms such as GitLab CI, GitHub Actions, or Jenkins is desirable. Knowledge of OpenAPI and Swagger specifications for designing and generating API tests is beneficial. Basic understanding of Kubernetes concepts, including pods, nodes, resource limits, resource allocation, and eviction, is a plus. Experience using AI-assisted development tools, such as Claude Code or Cursor, including project context management and workflow automation, is an advantage. A continuous improvement mindset and enthusiasm for modern engineering practices, technical challenges, and professional development.
