Join a fast-growing cybersecurity company building privacy and security products used by millions of people worldwide. We're a fully remote global team, and we're looking for a QA Engineer to test our web applications, websites and browser extensions. The role combines manual Frontend and Backend testing, with a strong focus on APIs and Postman, plus AI agents to speed up testing and broaden coverage. Automation experience isn't required, but you'll be able to grow your Playwright and JavaScript/TypeScript skills on real projects.

• Perform manual Frontend and Backend testing of web applications and websites, with the ability to test native mobile applications on Android and iOS when required
• Test APIs and Backend logic in Postman, including positive and negative scenarios, integrations, data validation and error handling
• Use AI agent systems across the testing process: requirements analysis, test design, test execution and defect investigation
• Perform functional, integration, regression and exploratory testing
• Analyze requirements and contribute to test planning and test coverage
• Use JavaScript for QA tasks, analysis and work with test scenarios
• Investigate defects, write clear bug reports, verify fixes and take part in root cause analysis
• Work closely with Frontend and Backend developers, Team Leads and Product Managers to keep product quality high
• Find ways to improve QA processes with AI-assisted workflows and modern testing approaches
• Help improve test coverage, observability and overall QA efficiency

Requirements

• 4+ years of commercial QA experience with a strong focus on manual testing of Frontend and Backend, with additional experience in testing native mobile applications on Android and iOS
• Solid hands-on experience with Backend testing, including APIs, integrations, business logic, error handling and edge cases

• Strong analytical thinking and the ability to understand complex systems
• A proactive mindset with a strong focus on product quality and observability
• Bachelor's degree in a technical field or a completed recognized QA training program
• Comfortable using Hubstaff for time tracking (we use it for daily time logging, not employee monitoring)
