Automation Tester

Ignite quality at scale—design, automate, and evolve the test systems that keep modern platforms moving.

Warsaw-based opportunity with hybrid work model. (4 remote days/week)

As a Senior QA Automation Engineer, you will be working for our client, building reliable software through end-to-end test coverage—spanning REST/SOAP APIs, E2E flows, contract validation, and CI/CD automation. You’ll strengthen test frameworks, improve quality metrics, and help deliver stable releases faster through proactive defect diagnosis and clear, actionable reporting.

Your main responsibilities:

• Design, implement, and maintain automated tests for APIs (REST/SOAP) and E2E (Playwright + TypeScript).

• Create test scenarios and backend + end-to-end flow test cases using a risk-based approach.

• Validate API contracts, including error scenarios, to ensure correct behavior across integrations.

• Develop and refactor test frameworks in Java and TypeScript, keeping them maintainable and scalable.

• Analyze test results across functional, integration, and performance checks, and drive improvements based on findings.

• Diagnose defects by investigating logs, requests, and data, then document findings with full reproduction steps (including logs and recordings when needed).

• Maintain and grow test execution in CI/CD pipelines and perform code reviews for test assets in collaboration with developers.

• Support requirements analysis, refinement, and sprint planning, while contributing to the overall test strategy and quality metrics.

You're ideal for this role if you have:

• 5+ years of experience in automated testing (API and/or E2E).

• Very strong knowledge of Java for backend automation.

• Strong TypeScript/JavaScript skills.

• Experience with API testing (REST), using tools such as Rest Assured and/or Gatling.

• Proven experience with E2E automation using Playwright.

• Working knowledge of SQL for data validation.

• Experience with Git (PRs & code review).

• Practical experience with CI/CD (Jenkins, GitLab, GitHub Actions, or Azure DevOps) plus Maven or Gradle.

• Ability to work effectively in Agile/Scrum environments.

It is a strong plus if you have: (optional)

• Experience with performance testing (e.g., Gatling).
• Knowledge of microservices architecture.
• Experience with tools like Swagger and API mocking.
