This role focuses on ensuring the quality, reliability, and performance of billing systems within the Clover EMEA platform. As the billing domain expands across additional markets, strong automated testing and performance validation are required to maintain system stability and reduce production defects.

• Integrate automated tests into CI/CD pipelines to support continuous delivery

• Review test and automation code to ensure quality, maintainability, and consistency with best practices

• 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:

• Experience with additional automated testing frameworks or tooling

• 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
