We’re looking for a hands-on QA Automation Engineer with strong front-end (UI) testing expertise who takes quality seriously and isn’t afraid to advocate for it.
This role requires someone who is confident in their technical judgment and comfortable challenging decisions, blocking releases when necessary, and voicing strong, experience-based opinions to ensure the highest quality standards.
You’ll work closely with developers to design, build, and maintain automated test suites across the full application stack — with a particular emphasis on UI/browser testing, supported by API and performance testing.
This is a role for someone who is self-motivated, quality-driven, and comfortable working independently within a collaborative Agile environment.
- Perform cross-browser testing across Chrome, Firefox, Safari, Edge, and others
- Validate front-end functionality, UI consistency, responsiveness, and accessibility basics
- Build and maintain automated UI tests using tools such as Playwright or Selenium
- Identify and report UI/UX, rendering, and performance issues early
- Design and maintain E2E test scenarios covering complete user workflows
- Integrate automated tests into CI/CD pipelines in collaboration with developers
- Create and maintain API test cases using tools such as Postman or similar
- Validate authentication, data integrity, error handling, and response behavior
- Ensure consistent and correct API responses across edge cases
- Execute performance tests using tools like k6 or Apache JMeter
- Simulate load and stress scenarios to evaluate system limits
- Collaborate with developers to identify and resolve bottlenecks
- Reproduce and investigate issues across UI, API, and system levels
- Work closely with developers to resolve defects efficiently
- Act as a quality gatekeeper — confidently raise concerns and block releases when necessary
- Leverage AI tools to improve test coverage, design, debugging, and productivity
