Descrição da vaga

Type: Onsite

Welcome to DKB AG….   

We’re excited to share that our hiring process is now led by Code Factory (CoFa), DKB’s sister tech company, bringing a more agile and collaborative approach to building our cross‑functional teams. While you’ll go through the hiring journey with CoFa, your employment will be with DKB, combining the stability of a leading bank with the speed and innovation of a tech‑driven environment. Join us to be part of a team where collaboration and impact come first.  

Your responsibilities:

• You work with developers and product teams to develop a suitable testing strategy for our backend systems and ensure sensible test coverage across different testing levels.
• You design, implement, and maintain automated tests for our APIs and microservices, ensuring that our test automation remains stable and maintainable as complexity grows.
• You decide which tests make sense at the unit, API/integration, or end‑to‑end level, and help avoid duplication between testing levels.
• You integrate automated tests into our CI/CD pipelines, analyze test results, and help identify errors and quality risks early in the development process.
• You analyze and debug failed and unstable tests, and continuously improve existing test frameworks and processes.
• You actively contribute to our quality engineering efforts, identify quality risks with the team, and decide where test automation adds real value.
• You work closely with developers, product owners, business teams, and other QA engineers, making quality a shared part of product development.

Following qualifications would be in line with our desired profile for this position:

• You have a completed degree in a STEM field, equivalent training, or relevant practical experience in software development or quality assurance.
• You have solid experience in test automation and can structure it to remain maintainable, reliable, and scalable over the long term.
• You have practical programming experience with Java and write readable, maintainable test code. Experience with Serenity BDD is a plus; alternatively, you’re willing to learn it.
• You’re familiar with testing APIs and microservices and have a good understanding of distributed backend systems and synchronous and asynchronous communication.
• You’re familiar with the fundamentals of event‑driven architectures; ideally, you’ve already worked with Apache Kafka or similar technologies.
• You have experience with CI/CD pipelines and understand how automated tests are integrated into the development and delivery process.
• To you, quality means more than running test cases: you identify risks, question existing test coverage, and contribute ideas to improve our testing strategy and automation.
• You work independently, in an organized and solution‑oriented way, and enjoy learning about new technologies and subject areas.
• You communicate technical and quality‑related topics confidently with different stakeholders and adapt the level of detail to your audience.
• Confident communication in German and English, ideally at B2 level or above

By the way: At our company, every person matters. We embrace fairness and diversity—no matter where you’re from, how old you are, or your sex, gender identity, sexual orientation, or religion, whether you have a disability or not—we genuinely look forward to every application!
