- Analyze test outcomes, produce quality metrics, and communicate risks and issues effectively.
- Mentor junior QA engineers and support the implementation of automation best practices across teams.
Required Skills & Experience:
- 4–6 years of hands-on experience in QA and test automation roles, preferably within Agile settings.
- Proficiency in coding with Java, Kotlin, or similar languages, evidencing a track record of building sustainable test automation code.

- Strong background in CI/CD pipelines and tools such as Jenkins and GitHub Actions.
- Familiarity with cloud-native architectures and container technologies like Docker and Kubernetes.
- Experience in testing distributed systems and microservice architectures.
- Strong analytical and problems-solving skills, coupled with excellent communication and collaboration abilities.
Nice to Haves:
- Exposure to financial services, fintech, or trading system technologies.
- Prior experience overseeing test strategy for medium-to-large projects or components.
- Familiarity with tools like XRAY, TestRail, Grafana, Kibana, or Prometheus for test management and observability.
- Understanding of performance, reliability, or security testing approaches.
What You'll Gain:
- Opportunities to contribute to and influence the test strategy for critical product components.
- The opportunity to help shape the direction of test frameworks and tooling.
- Chances to mentor junior team members and contribute to QA best practices.
- A dynamic and collaborative team environment with modern DevOps and agile workflows.
