  • Collaborate with developers, product managers, and DevOps engineers in Agile ceremonies to ensure test coverage aligns with business needs
  • 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

  • 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

  • A chance to work with a challenging product in the DLT domain
  • Opportunities to contribute and shape the test strategy for key product components
