About the role:
We're looking for a hands-on QA Automation Engineer who takes quality seriously and isn't afraid to speak up for it. You'll be working closely with our development team to design, build, and maintain automated test suites across the full application stack — from browser and UI to APIs, performance, and stress testing.
This is a role for someone who is self-motivated, quality-obsessed, and comfortable working independently in a collaborative Agile environment.
What you will do:
- Perform cross-browser testing across Chrome, Firefox, Safari, Edge, and others
- Validate front-end functionality, UI consistency, responsiveness, and basic accessibility requirements
- Identify and report compatibility, rendering, and performance issues using tools like Playwright or Selenium
- Design, execute, and maintain E2E test scenarios covering complete user workflows
- Integrate automated E2E tests into CI/CD pipelines in collaboration with developers
- Create and maintain test cases for API endpoints
- Test authentication, data integrity, error handling, and response times
- Ensure correct error codes and responses are returned under all expected conditions
- Execute performance tests to measure system responsiveness under load
- Design stress test scenarios to evaluate system limits and resilience under unexpected traffic spikes
- Collaborate with developers to identify and resolve bottlenecks
- Quickly reproduce and investigate issues across the stack
- Work closely with developers to resolve bugs efficiently
- Leverage AI tools to improve test design, automation, troubleshooting, and overall efficiency
