    • Contribute to the test planning and own the execution for assigned features or product areas, ensuring timely and high-quality releases
    • Log, prioritize, and manage defects using tracking tools like JIRA
    • Analyse test results, generate quality metrics, and clearly communicate risks and issues
    • Mentor junior QA engineers and help drive automation best practices across teams

Required Skills & Experience

    • Strong coding skills in Java, Kotlin, or similar languages, with demonstrated experience building maintainable test automation code
    • 4-6 years of hands-on experience in test automation and manual QA roles, ideally in Agile environments
    • Proficient in using test automation frameworks and tools such as:
    • UI Testing: Selenium, Cypress, Appium
    • API Testing: REST Assured, Postman, SoapUI
    • BDD Tools: Cucumber, Serenity
    • Database Testing
    • Solid experience with CI/CD pipelines and tools (e.g., Jenkins, GitHub Actions)
    • Familiarity with cloud-native architectures and container technologies like Docker and Kubernetes
    • Experience testing in distributed systems and microservice architectures
    • Strong analytical and problem-solving abilities
    • Excellent communication and collaboration skills

Nice to Haves

    • Exposure to financial services, fintech, or trading system technologies
    • Experience leading 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
    • ISTQB/CSTE certification

What You'll Gain

    • Opportunities to contribute and shape the test strategy for key product components
    • The chance to help shape test frameworks and tooling direction
    • Opportunities to mentor junior team members and contribute to QA best practices
    • A fast-paced, collaborative team environment with modern DevOps and agile workflows
