Key Responsibilities

• Design, develop, and maintain scalable Python-based test automation frameworks from the ground up.
• Build robust web application automation using Playwright with Python, following modern automation architecture and engineering practices.
• Develop reusable automation libraries, utilities, fixtures, test-data components, and framework capabilities that can be leveraged across applications and teams.
• Develop automated tests covering UI, API, integration, regression, and end-to-end workflows.
• Translate product requirements, test cases and acceptance criteria into reliable and maintainable automated test scenarios.
• Design automation solutions using appropriate framework architecture and design patterns such as Page Object Model (POM) and other reusable component-based approaches.
• Develop and maintain API automation for REST-based services, including request/response validation, authentication, data validation, and integration workflows.
• Integrate automated test suites into CI/CD pipelines to enable continuous testing and faster feedback to development teams.
• Analyze automation execution results, troubleshoot failures and flaky tests, perform root-cause analysis, and continuously improve framework reliability.
• Participate in automation code reviews and ensure adherence to Python coding standards, automation design principles, and software engineering best practices.
• Identify opportunities to improve test coverage, execution speed, framework scalability, maintainability, and overall automation effectiveness.
• Evaluate and apply AI-assisted and agentic engineering approaches for areas such as test generation, automation code development, test maintenance, failure analysis, debugging, and engineering productivity.
• Build reusable prompts, workflows, agents, skills, or automation utilities where AI can improve the efficiency and effectiveness of quality engineering activities.
• Collaborate with developers, product owners, quality engineers, DevOps engineers, and other cross-functional teams to drive quality throughout the software development lifecycle.
• Contribute to automation architecture, technical standards, reusable accelerators, engineering practices, and continuous improvement initiatives.
• Provide technical guidance and mentoring to other automation engineers based on experience and role expectations.

Required Qualifications

• Bachelor's degree in Computer Science, Software Engineering, Information Technology, Engineering, or a related technical discipline.
• 5–12 years of experience in software quality engineering, test automation, software development, or related engineering roles.
• Strong hands-on programming experience in Python, with the ability to write clean, modular, reusable, and maintainable production-quality automation code.
• Strong hands-on experience with Playwright automation using Python or significant experience with modern browser automation frameworks combined with the ability to work extensively with Playwright.
• Proven experience designing, developing, or significantly enhancing test automation frameworks.
• Strong understanding of automation framework architecture, reusable component design, object-oriented programming, and software design principles.
• Hands-on experience with Python testing frameworks such as pytest or equivalent frameworks.
• Experience developing automation for REST APIs and integration workflows.
• Experience with web technologies and browser automation concepts including DOM, XPath/CSS selectors, browser contexts, network interactions, asynchronous behavior, and cross-browser testing.
• Experience integrating automation suites with CI/CD pipelines using Jenkins or equivalent platforms.
• Experience with Git, branching strategies, pull requests, and code-review practices.
• Strong debugging and root-cause analysis skills with the ability to troubleshoot application, automation framework, test-data, and environment-related failures.
• Good understanding of Agile software development, software testing methodologies, and modern quality engineering practices.
• Strong analytical, problem-solving, communication, and collaboration skills.

Preferred Qualifications

• Advanced experience building Playwright + Python automation frameworks from the ground up.
• Experience designing reusable automation frameworks and libraries for use across multiple products or engineering teams.
• Experience with AI-assisted software development and test automation tools such as GitHub Copilot, OpenAI Codex, or equivalent technologies.
• Hands-on exposure to agentic AI approaches, including developing or using AI agents, skills, prompts, or workflows for software engineering or test automation use cases.
• Experience applying Generative AI/LLMs to test-case generation, automation-code generation, test maintenance, failure analysis, defect investigation, or engineering productivity.
• Experience with test reporting and observability solutions such as Allure, Playwright reporting, dashboards, or equivalent technologies.
• Familiarity with Behavior-Driven Development (BDD) using Behave, pytest-bdd, Cucumber/Gherkin, or similar frameworks.
• Exposure to performance, accessibility, security, or other non-functional automation approaches.
• Experience mentoring engineers, conducting technical reviews, or contributing to automation architecture and technical strategy.
