• Salesforce testing experience (UI, API, data integrity, permission sets).
• Proven experience building and maintaining automated test suites integrated into CI/CD pipelines.
• Strong API testing expertise and experience with tools for web and desktop applications (functional, contract, negative, and basic performance/security).
• Ability to perform manual testing for non-CI/CD applications.
• Security testing awareness (authN/authZ, Postman/ReadyAPI security tests).
• Experience testing web applications (Selenium, Playwright, Cypress or similar) and desktop applications (e.g., WinAppDriver or similar).
• Solid programming or scripting skills (e.g., C#, Java, TypeScript/JavaScript, or Python) for test automation.
• Experience with version control and workflows (Git, branching strategies, PR reviews).
• Familiarity with test management/defect tracking (e.g., Jira or equivalent).
• Strong analytical thinking, debugging skills, and a bias for automation and continuous improvement.
• Excellent written and verbal communication.
