In the Global Bank Team at SumUp we are building the infrastructure and core services needed to provide our merchants with a digital bank account that allows them to be successful at doing what they love. Our goal is to become the most popular banking partner for small merchants globally by offering a high-quality banking experience tailored to small business needs - effortless, simple and affordable.
As our global banking platform continues to grow, so does the feature-set we support and the technology estate upon which it’s built.
Therefore we are seeking Software Development Engineers in Test (SDET) to join our team. You’ll collaborate across the Global Bank team to improve software quality through automated testing practices. Shape our test strategy, build test packs, identify quality gaps, and integrate automated tests from mobile UI to data tier. Help us to accelerate delivery while maintaining a high quality bar.

• Integrate testing methodologies and practices within teams, fostering a culture of quality assurance.
• Write unit, automated component, contract, integration, and end-to-end tests.
• Provide end-to-end support for performance and load testing, including workload modeling, test execution and results analysis.
• Collaborate closely with software and DevOps engineers for seamless deployment and continuous integration.
• Utilize metrics to identify areas for improvement and guide engineers with actionable steps.
• Assist in maintaining test suites, build pipelines, and test data.

YOU’LL BE GREAT FOR THIS ROLE IF:

• You have programming experience in any language (e.g., Kotlin, Python, JS, Go, Elixir, Java, Ruby).
• You have mobile automation experience with coding.
• You have experience managing build pipelines, integrating tests, and working with Continuous Deployment.
