• Build and maintain E2E, integration, smoke, and regression test suites and integrate them into CI/CD pipelines (e.g., GitHub Actions, Argo, Jenkins with Groovy, Azure).
• Implement and manage automation tools and frameworks (Bruno, Insomnia, Cypress, REST Assured, Postman, Playwright), including selection, setup, configuration, maintenance, and governance to drive scalable, reliable test automation across teams.
• Conduct thorough functional, UI, and API testing to verify features meet acceptance criteria.
• Perform end-to-end testing across frontend and backend systems, validating UI/UX behavior, API responses, logs, and database integrity.
• Identify, document, prioritize, and track software defects with detailed root-cause analysis; collaborate with developers and business analysts for timely resolution.
• Mentor junior test engineers, provide code reviews, and promote continuous improvement in testing practices.
• Communicate testing strategy, progress, reports, risks and results clearly to stakeholders and cross-functional teams.
• Collaborate with distributed teams including developers, QA engineers, product managers, and project managers to ensure high-quality, on-time delivery.
• Advocate for QA process improvements, testability, and automation-first approaches.
• Participate in knowledge-sharing sessions, mentoring, and team-building activities aligned with CSC’s values.

What technical skills, experience, and qualifications do you need?

• Bachelor’s degree in Computer Science, Information Technology, or a related field, or equivalent practical experience.
• 6 years of experience in software testing, with strong hands-on background in both manual and automation testing.
• Strong understanding of QA methodologies, test strategies, and SDLC/STLC processes.
• Proficiency with test automation frameworks such as Selenium, Cypress, Playwright, or similar.
• Experience building automation for web UIs and APIs using TypeScript, Java, Python, and/or Node.js.
• Experience with API testing tools such as Postman or Bruno, and/or frameworks like REST Assured.
• Solid understanding of frontend and backend technologies including HTML/CSS, JavaScript, RESTful APIs, and databases.
• Familiarity with CI/CD tools and practices; experience with Jenkins, GitLab CI, or Azure DevOps. Experience integrating tests into pipelines (e.g., GitHub Actions, Argo, Jenkins/Groovy, Azure).
• Experience working in Agile/Scrum environments with iterative delivery and backlog-driven planning.
• Excellent analytical and problem-solving skills with strong attention to detail and quality.
• Strong verbal and written communication skills, with the ability to convey technical concepts to diverse audiences.
• Proven ability to mentor junior team members and foster a collaborative team environment.
• Proficiency in creating detailed test documentation, test plans, and effectively tracking defects.
• Basic proficiency in SQL for data validation and database verification.

Nice to have:

• Experience with ALM Octane for test and defect management.
• Exposure to performance testing concepts and best practices.
• Understanding of container architecture (OpenShift, Kubernetes, AWS, Azure)
• Understanding of Application monitoring (Elastic, Splunk)
• Experience with AI-first/AI-assisted testing approaches (LLM-driven test case generation, test prioritization and flakiness detection, computer-vision-based UI validation).
• Familiarity with AI testing tools and platforms (BrowserUse)
• Experience using AI assistants to accelerate automation and documentation (GitHub Copilot/Cursor) and leveraging LLMs/AI services (OpenAI, Vertex AI) for synthetic test data generation and API contract testing.
