About the role

We are looking for a Senior Test Automation Engineer to join our QA team in a fully remote capacity. Your primary mission will be to accelerate our automation coverage and clear a significant backlog of manual test cases by bridging the gap between requirements and code.

With our automation framework already established, we need an experienced engineer who can take a feature from a user story to a fully automated suite. This role requires a strong focus on GraphQL API testing, manual test design, and UI automation using TypeScript and Playwright.

What you’ll do

• End-to-End Testing Workflow: Take ownership of the full testing lifecycle for new features by analyzing User Stories, designing comprehensive Manual Test Cases, and transitioning them into robust Automated Regression Scripts.
• Scaling Automation: Expand and maintain our existing Playwright + TypeScript automation suite, ensuring scripts are stable, readable, and efficient.
• Backlog Conversion: Actively transform the existing backlog of manual tickets and functional requirements into automated scripts.
• GraphQL API Testing: Design and execute automated tests for GraphQL APIs, ensuring schema integrity and valid data responses across our services.
• Manual Testing: Perform thorough manual testing on web application features to validate UI/UX and identify edge cases before they are automated.
• CI/CD Integration: Work within our CI/CD pipelines (e.g., GitHub Actions) to ensure automated suites provide rapid, reliable feedback to the engineering team.
• Quality Standards: Review test code and collaborate with the team to maintain high standards for test data management and script reliability.

Who you are

• Experience: 5+ years in Software Quality Engineering with a heavy focus on automation.
• Coding Proficiency: Strong experience in TypeScript. You should be comfortable writing clean, maintainable code and working within an existing framework.
• Playwright Expertise: Proven experience building and maintaining UI automation with Playwright.
• GraphQL Mastery: Hands-on experience testing GraphQL APIs (e.g., using Playwright’s APIRequest, Apollo, or similar tools).
• Manual Design: Proficiency in breaking down complex user stories into structured manual test cases that serve as the blueprint for automation.
• Web Testing: Deep understanding of web technologies (DOM, CSS, DevTools) and experience testing complex enterprise web applications.

Nice to have

• AI‑Assisted Development: Proficiency in using AI‑powered tools (e.g., GitHub Copilot, Cursor) to accelerate script generation, refactoring, and debugging.
• Project Management Tools: Experience working in Agile environments using Click‑Up and Notion for task tracking and documentation.
• Advanced GraphQL: Familiarity with testing subscriptions or complex schema stitching.

How we work

Due to the highly collaborative and internationally distributed nature of our work, successful candidates must be comfortable operating in small teams while contributing to larger, globally coordinated efforts. A strong sense of ownership, self‑motivation and discipline in maintaining clear and consistent communication through virtual collaboration tools and video conferencing is essential.
