  • Build and maintain automated tests for microservices, validating service interactions and system behaviour
  • Investigate failures from automated tests and production issues, and work with developers to identify root causes
  • Maintain documentation for test cases, performance benchmarks, and testing processes
  • Increase overall test coverage and reduce regressions across releases

What you will need to have:
  • 3-5 years of experience in an SDET or quality engineering role
  • Strong Java development skills, understanding applications developed with the Spring framework
  • SQL experience to query relational databases
  • Scripting knowledge (Python is preferred)
  • Hands-on experience with test automation frameworks such as Karate or equivalent
  • Experience with performance testing tools such as JMeter
  • Understanding of microservices architecture and distributed systems
  • Experience testing applications deployed on Kubernetes or similar container platforms
  • Strong debugging and analytical problem-solving skills
  • Experience working within Agile engineering teams
  • Bachelor's degree in Computer Science or a related discipline, or equivalent practical experience
  • 3-5 years of professional experience in software testing or quality engineering roles

What would be great to have:

  • Familiarity with CI/CD tooling and pipeline integration
  • Basic understanding of security testing principles
  • Knowledge of software development lifecycles and release processes
  • Formal certification in software testing or quality engineering
