QA Engineer (Full stack)

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.

What you will do

• Perform manual Frontend and Backend testing of web applications and websites.
• 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.

What we are looking for

• 2+ years of commercial QA experience, with a strong focus on manual testing of both Frontend and Backend.
• Solid hands-on experience with Backend testing, including APIs, integrations, business logic, error handling and edge cases.
• Strong practical knowledge of Postman for API testing.
• Strong knowledge of JavaScript and the ability to apply it to QA tasks.
• Experience using AI agent systems and AI-assisted workflows for software testing.
• Experience testing browser extensions.
• Experience with functional, integration, regression and exploratory testing.
• Solid understanding of software testing principles and the ability to apply them in practice.
• Experience creating and maintaining test documentation.
• Confident use of Chrome DevTools, Figma, project management tools and test management platforms.
• Experience working with developers, Team Leads and Product Managers.
• 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.

Nice to have

• Experience with Playwright and JavaScript/TypeScript test automation.
• Experience with other test automation frameworks.
• Experience using AI coding assistants for test automation or QA tasks.
• Experience building AI agents or AI-powered workflows.
• Knowledge of TypeScript or other programming languages.
• Experience testing WordPress-based applications.
• Experience with Docker and CI/CD pipelines.

What we offer

• Build personal AI agents using our premium infrastructure.
• Work remotely from anywhere within GMT+1 to GMT+5.
• Internal R&D opportunities.
• Paid time off and sick leave.
• Direct impact on a large-scale global B2C product.
• A collaborative international team.
• Hardware after you complete probation.
